discussion of cumulative impacts ignores foreseeable impacts from probable future

projects; (b) finding of consistency with the Regional Transportation Plan is not

supported by substantial evidence; and (c) analysis of alternatives ignores a smart-growth

alternative.

3 To be abundantly clear, our holdings are necessarily limited to the facts of this

case, and in particular, M-GHG-1. Our decision is not intended to be, and should not be

construed as blanket prohibition on using carbon offsets—even those originating outside

of California—to mitigate GHG emissions under CEQA.

Similarly, our holding regarding the CAP's invalidity is a narrow one. The

judgment requiring the County to set aside and vacate its approval of the CAP is affirmed

because the CAP's greenhouse gas emission projections assume effective implementation

of M-GHG-1, and M-GHG-1 is itself unlawful under CEQA. Except to the extent that

(1) the CAP is impacted by its reliance on M-GHG-1; and (2) the CAP's inventory of

greenhouse gases is inconsistent with the SEIR (see part IX, post), the CAP is CEQA-

compliant.

This is the third time the County's attempt to adopt a viable climate action plan

and related CEQA documents has been before this court. In an attempt to avoid a fourth,

we further note that the CAP contains a GHG reduction measure (T-4.1) designed to

offset in-County GHG emissions. As explained post, T-4.1 significantly differs from

M-GHG-1 in several respects and, perhaps more importantly in indicating the types of

offset protocols that might pass muster, is unchallenged in this litigation.

FACTUAL BACKGROUND

A. Overview

This is a complex case, in part because of the size of the record (approximately

72,000 pages), and the extensive litigation history, which spans nearly a decade with two

4 prior opinions from this court.2 We begin with an overview of some of the key

documents in the case. Because acronyms are used throughout, a glossary is appended at

the end of this opinion.

1. GHG emission reduction

"Greenhouse gases absorb infrared radiation and trap the heat in the Earth's

atmosphere, rather than allowing the radiation to escape into space. . . . [¶] Fossil fuel

combustion is the source of the vast majority of the United States' [GHG] emissions. . . .

In 2010, California produced 452 million metric tons (MT) of CO2e.[3] The

transportation sector was the largest contributor to California's [GHG] emissions,

producing 38 percent of the state's total. . . ." (Irritated Residents, supra, 17 Cal.App.5th

at pp. 731-732.)

The Legislature has "emphatically established as state policy the achievement of a

substantial reduction in the emission of gases contributing to global warming." (Center

for Biological Diversity v. Department of Fish & Wildlife (2015) 62 Cal.4th 204, 215

(Center for Biological Diversity).) This policy is implemented in CEQA.

2 Sierra Club v. County of San Diego (2014) 231 Cal.App.4th 1152 (Sierra Club I) and Golden Door Properties, LLC v. County of San Diego (2018) 27 Cal.App.5th 892 (Golden Door).

3 The capacity of each GHG to retain heat varies. Emissions of GHGs are expressed as MTCO2e, which is the amount of carbon dioxide in metric tons that would have the same global warming potential as the emission of the particular GHG. (Association of Irritated Residents v. Kern County Bd. of Supervisors (2017) 17 Cal.App.5th 708, 731, fn. 6 (Irritated Residents).)

5 CEQA requires a lead agency to "make a good-faith effort, based to the extent

possible on scientific and factual data, to describe, calculate or estimate the amount of

[GHG] emissions resulting from a project." (Cal. Code Regs., tit. 14, § 15064.4, subd.

(a).)4 In determining the significance of a project's GHG emissions, CEQA directs the

lead agency to consider, among other things, the "extent to which the project complies

with regulations or requirements adopted to implement a statewide, regional, or local plan

for the reduction or mitigation of [GHG] emissions." (Guidelines, § 15064.4, subd.

(b)(3).)

The California Air Resources Board (CARB) is "the state agency charged with

monitoring and regulating sources of emissions of greenhouse gases that cause global

warming in order to reduce emissions of greenhouse gases." (Health & Saf. Code,5

§ 38510.) CARB has pursued several strategies for reducing GHG emissions, including a

cap-and-trade program. (Cal. Code Regs., tit. 17, §§ 95801-96022; Association of

Irritated Residents v. State Air Resources Bd. (2012) 206 Cal.App.4th 1487, 1498, fn. 6.)

2. Cap-and-trade

" 'Cap-and-trade is a market-based approach to reducing pollution. The "cap"

creates a limit on the total amount of emissions from a group of regulated sources, and

4 The CEQA Guidelines in title 14 of the California Code of Regulations, section 15000 et seq., are hereafter cited as Guidelines. We give them great weight "except where they are clearly unauthorized or erroneous." (Center for Biological Diversity, supra, 62 Cal.4th at p. 217, fn. 4.)

5 Undesignated statutory references are to the Health and Safety Code.

6 generally imposes no particular emissions limit on any one firm or source.' "

(Association of Irritated Residents v. State Air Resources Bd., supra, 206 Cal.App.4th at

p. 1498, fn. 6.) " 'The "trade" aspect of a cap-and-trade program creates an incentive for

businesses to seek out cost-effective reductions, while also encouraging rapid action to

reduce emissions quickly. Regulated entities receive allowances . . . representing the

right to emit a ton of greenhouse gas emissions. At specified intervals, regulated

businesses must surrender an allowance for each ton of GHG . . . they release. Over time,

the total amount of allowances available to all sources is reduced, meaning overall

emissions from those sources must be also reduced. If an individual source does not need

all of the allowances it has in a given period, it may "bank" those allowances to surrender

later or sell them to another registered party. The ability to sell allowances to other

businesses that need them creates a market price for pollution reductions and an incentive

for businesses to achieve the maximum reductions possible at the lowest cost.' " (Ibid.)

Thus, under cap-and-trade, GHG emitters may comply with the cap by purchasing

GHG reductions that others achieve, called offsets. Offset credits can be produced by a

variety of activities that reduce or eliminate GHG emissions or increase carbon

sequestration.6

Under cap-and-trade, offset projects must comply with rules and procedures—

called Compliance Offset Protocols (CARB Protocols), which CARB adopts and

6 Carbon emissions are sequestered, for example, by trees, which absorb carbon from the atmosphere.

7 administers through an Offset Project Registry (OPR). (Cal. Code Regs., tit. 17,

§§ 95973, subd. (a)(1); 95987, subd. (a).) OPRs facilitate "the listing, reporting, and

verification of offset projects developed using the [Protocols], and issue registry offset

credits."7 OPRs must be approved by CARB and "shall use [CARB Protocols] to

determine whether an offset project may be listed . . . for issuance of registry offset

credits." (Cal. Code Regs., tit. 17, §§ 95986; 95987, subd. (a).) Entities can use offsets

to fulfill only up to 8 percent of their compliance obligation. (Id., § 95854, subd. (b).)

GHG offsets "must be real, additional, quantifiable, permanent, verifiable, and

enforceable." (Cal. Code Regs., tit. 17, § 95802, subd. (a).) Numerous statutes and

regulations are designed to ensure these criteria are met. (Health & Saf. Code, § 38562;

Cal. Code Regs., tit. 17, § 95100 et seq.)

3. The broad contours of this case

This case involves the County's (1) CAP; (2) associated General Plan Amendment

to the County's 2011 General Plan Update (GPU); (3) a threshold of significance for

GHG emissions; and (4) Guidelines for Determining Climate Change—collectively the

7 (OPR [as of June 12, 2020] archived at ).

8 "Project." The County as lead agency prepared the Project's SEIR, which addresses GHG

impacts in the County's unincorporated areas and from County operations.8

The superior court determined that the CAP is inconsistent with the GPU and,

therefore, invalid. The court also determined that M-GHG-1 violates CEQA by

(1) requiring the purchase of out-of-County offsets without legally sufficient analysis;

and (2) unlawfully delegating and deferring feasibility findings. The superior court

further determined that the SEIR violates CEQA by inadequately analyzing

(a) cumulative GHG impacts; (b) impacts to "energy and environmental justice"; and

(c) "smart growth mitigation or alternatives for [General Plan Amendment projects]."

The court also determined that the County violated CEQA by failing to properly respond

to comments on the draft SEIR (DSEIR).

Documents discussed throughout this opinion, introduced here and explained in

more detail later, are:

(1) 2011 General Plan Update (GPU): A comprehensive, long- term plan for developing unincorporated areas of the County. Calls for reducing GHG emissions to meet state GHG targets, and requires preparation of a Climate Action Plan to achieve this reduction.

(2) 2011 Program Environmental Impact Report (PEIR): Analyzes environmental impacts from implementing the GPU. Requires a climate action plan be prepared.

10 B. The GPU

The unincorporated County contains 3,570 square miles and as shown in the map

post, is mostly undeveloped.

In 2011, the County updated its general plan, establishing "a blueprint for future

land development projects in the unincorporated County that meets community desires

and balances the environmental protection goals with the need for housing, agriculture,

infrastructure, and economic vitality."

The GPU contains principles guiding future growth that are intended to retain the

County's "rural character, economy, and unique communities, as well as minimizing the

environmental impacts of future development." To accomplish these goals, the GPU

"shifts growth capacity from the eastern backcountry areas to western communities" by

encouraging growth "in villages with 'compact land development patterns to minimize

intrusion into agricultural lands and open spaces; reduce travel distances to local services

11 and businesses, while also inducing community association, activity, and walking.' " The

GPU seeks to "develop lands and infrastructure more sustainably in the future."9

The GPU contains a "Vision Statement" and "Guiding Principles." These

"represent[] the basis by which all updated plan goals, policies, and implementation

programs are measured . . . ." Addressing GHG emissions, the Vision Statement

provides:

"[T]he Land Use Map provides a mix and density of land uses that will minimize automobile trips and their length, invigorate the economic health of our businesses, and promote association with our neighbors. These, coupled with increased access to transit, will reduce our air emissions, greenhouse gas emissions, energy consumption, [and] noise . . . ."

C. Climate Change Legislation

California's "landmark legislation addressing global climate change, the California

Global Warming Solutions Act of 2006," is commonly referred to as Assembly Bill

No. 32 (Assem. Bill No. 32). (Center for Biological Diversity, supra, 62 Cal.4th at

p. 215.) Assem. Bill No. 32 calls for reducing GHG emissions to 1990 levels by 2020.

(Ibid.)

In 2016, the Legislature enacted Senate Bill No. 32 (Sen. Bill No. 32), "which

adopts a goal of reducing [GHG] emissions by 40 percent below 1990 levels by the year

9 Sustainability means "simultaneously meeting our current economic, environmental, and community needs, while also ensuring that we are not jeopardizing the ability of future generations to meet their needs."

12 2030. This 40 percent reduction is widely acknowledged as a necessary interim target to

ensure that California meets its longer-range goal of reducing [GHG] emissions to

80 percent below 1990 levels by the year 2050." (Cleveland National Forest Foundation

v. San Diego Assn. of Governments (2017) 3 Cal.5th 497, 519 (Cleveland National).)10

These mandates are a key element of the GPU's goals and policies. GPU Goal

COS-20 (as originally adopted) provides for the "[r]eduction of local GHG emissions

contributing to climate change that meet or exceed requirements of the Global Warming

Solutions Act of 2006." Policy COS-20.1 likewise provides that the County shall

"[p]repare, maintain, and implement a climate action plan with a baseline inventory of

GHG emissions from all sources; GHG emissions reduction targets and deadlines, and

enforceable GHG emissions reduction measures."11

One of the GPU's guiding principles is that "land should be developed more

compactly, resulting in reduced automobile use and increased use of public transit,

10 Sierra Club's request for judicial notice of Executive Order No. B-30-15, pertaining to the 40 percent reduction target, is denied as irrelevant. (San Diegans for Open Government v. San Diego State University Research Foundation (2017) 13 Cal.App.5th 76, 90, fn. 8 (SDOG).)

11 As part of the Project, the County amended COS-20 and COS 20.1 in 2018. COS 20 as amended provides: "Reduction of community-wide (i.e., unincorporated County) and County Operations greenhouse gas emissions contributing to climate change that meet or exceed requirements of the Global Warming Solutions Act of 2006, as amended by [Sen. Bill No. 32] . . . ." As amended, COS-20.1 provides, "Prepare, maintain, and implement a Climate Action Plan for the reduction of community-wide (i.e., unincorporated County) and County Operations greenhouse gas emissions consistent with . . . Guidelines Section 15183.5."

13 walking, and bicycling. This will result in less consumption of gasoline, generation of

less air pollution and GHG emissions, the preservation of greater amounts of habitat and

agricultural lands, and the improvement of the lifestyles and health of community

residents." The GPU promotes reductions in vehicle trips, gasoline consumption, and

GHG emissions by containing 41 "mobility strategies."

D. The PEIR

The PEIR addresses the environmental impacts from implementing the GPU.12

The PEIR did not "speculate on the individual environmental impacts of specific future

development projects," but rather considered "build-out of the General Plan land use

designations up to forecasted population and housing unit totals."

Growth consistent with the GPU would create in-County GHG emissions.

Mitigation measures are necessary to achieve state GHG reduction targets. PEIR

mitigation measure CC-1.2 requires the County to prepare a climate action plan with

"comprehensive and enforceable GHG emissions reduction measures" to achieve

mandated GHG targets.

The County adopted the GPU and certified the PEIR in August 2011.

12 A program EIR considers " 'a series of actions that can be characterized as one large project and are related . . . .' " (Guidelines, §15168, subd. (a).) This allows the lead agency to consider "broad policy alternatives and program wide mitigation measures. . . ." (Cleveland National Forest Foundation v. San Diego Assn. of Governments (2017) 17 Cal.App.5th 413, 425 (Forest Foundation).)

14 E. The 2018 CAP

1. The CAP applies to projects that are consistent with GPU-allowed land use

Broadly speaking, there are two types of development projects in the County. One

type is a project proposing land use that is completely consistent with that allowed under

the General Plan. The other type is a project proposing intensity or density of land use

exceeding that allowed under the General Plan—that is, a project requiring a general plan

amendment.

"The scope of the CAP is to serve as mitigation to reduce GHG emissions

resulting from buildout of the 2011 GPU . . . ." In other words, to the extent a project is

consistent with land use allowed under the GPU, the project applicant must mitigate

GHG emissions with CAP GHG reduction measures.

2. The CAP's GHG inventory

The CAP establishes a baseline inventory of GHG emissions against which to

measure future reductions. The baseline consists of GHG emissions from activities

within the unincorporated County and from County operations as of 2014. Although

Assem. Bill No. 32 and Sen. Bill No. 32 use 1990 as a benchmark, 2014 is the most

recent year in which accurate information is available to inventory GHG emissions in the

unincorporated County. This inventory includes GHG emissions from projects requiring

a general plan amendment because of increased density or intensity of land use beyond

that allowed under the GPU (hereafter, such projects are referred to as GPAs), but only if

the GPA project was constructed as of 2014.

15 3. The CAP's GHG projections

The CAP also projects future GHG emissions for development consistent with

GPU allowed land use. These projections, based on current trends, population growth,

and known legislation, are called " 'business-as-usual' " projections. The projections

assume no additional local GHG reduction efforts and regulations will be undertaken, and

that population, housing, employment, and transportation will grow consistent with San

Diego Association of Governments (SANDAG) projections.

The CAP's GHG projections do not include GPA projects under review, but not

yet adopted by the County (hereafter referred to as in-process GPAs).13 However, the

projections include GHG emissions from GPA projects adopted between August 2011

(the date of the GPU) and August 2017 (the date the DSEIR was publicly released). The

projections also account for anticipated legislation that will reduce future emissions

without any additional County action. This includes, for example, anticipated increased

electric vehicle use.

The CAP's 2014 baseline and projected GHG emissions in MTCO2e are:

2014 Baseline 2020 Projection 2030 Projection 2050 Projection

3,211,505 3,018,671 2,824,049 2,991,507

13 Such projects are instead analyzed in the cumulative impact analysis in the SEIR, where M-GHG-1 applies.

16 4. GHG reduction targets and measures

To meet legislative GHG emission reduction targets, CARB recommends reducing

emissions to six MTCO2e per capita by year 2030 and to two MTCO2e per capita by

2050. This is equivalent to reducing 2014 emissions by 40 percent (by 2030) and 77

percent (by 2050). Therefore, to meet state targets, the County must reduce GHG

emissions to 1,926,903 MTCO2e by 2030 (40 percent below 2014 levels) and to 738,646

MTCO2e by 2050 (77 percent below 2014 levels).

The CAP contains 26 measures intended to meet these targets. "All [26] GHG

[r]eduction [m]easures in the CAP will be implemented within the unincorporated

County and from County operations . . . ." Likewise, all CAP GHG reduction measures

"will achieve GHG reductions locally (i.e., from County operations and within the

unincorporated County)."

The County "collaborated with over 50 stakeholder groups in the environmental,

business, and community sectors during a total of over 100 public events to gather input

to inform development of strategies and measures for the CAP. The primary determinant

for whether a measure was chosen was its GHG reduction potential and whether it would

help the County achieve its GHG reduction target in 2030. Measures were also assessed

for their applicability and effectiveness in the County's unique rural setting. . . . As

shown in the CAP, the selected measures are anticipated to meet state targets through

2030." All of the CAP's reduction measures "would need to be implemented . . . to meet

the reduction targets."

17 CAP measures include, for example, County acquisition of (1) open space, which

would reduce GHG emissions by preserving land that can otherwise be developed; and

(2) easements on agricultural land to extinguish future development potential. Under

another measure, the County will update 15 community plans by 2030, and an additional

four between 2031 and 2040 to incorporate a balanced approach to housing, jobs,

services, and infrastructure—including bike lane improvements, shared parking, and

community centers located in a core area. The CAP measures also include installing

electric vehicle charging stations, encouraging solar water heater installation, and

streamlining the permitting of solar energy production.

The CAP's GHG reduction measures may also produce "co-benefits"—"additional

jobs and economic development, cleaner air, fewer illnesses and disease, reduced energy

and water costs, or an overall improvement in the quality of life and public health."

5. CAP reduction measure T-4.1

Once implemented, the CAP's suite of measures may require adjustment to stay on

target. To provide needed flexibility, the CAP includes measure T-4.1, under which the

County may make "direct investments in local projects to offset carbon emissions."

"A direct investment project is created when a specific action is taken that reduces,

avoids, or sequesters GHG emissions." For example, the County could invest in a

weatherization project that reduces carbon emissions within the county while also

reducing residents' heating and cooling expenses. Other direct investment projects are

urban forest and urban tree planting.

18 Under T-4.1, the "County will not purchase carbon offset credits . . . but will . . .

track carbon offsets achieved through County direct investment projects" within the

unincorporated County. Emissions reductions occur, but unlike in cap-and-trade, offsets

are not traded as an independent commodity. The SEIR estimates that T-4.1 can achieve

176,614 MTCO2e reductions by 2030.

T-4.1 "would be implemented throughout the unincorporated County, where the

benefits of carbon sequestration and GHG emissions reductions would occur." Direct

investment projects must comply with (1) "established protocols that have been approved

by . . . CARB, the California Air Pollution Control Officers Association (CAPCOA), or

the San Diego County Air Pollution Control District"; (2) "that received 'public review

prior to adoption' "; and (3) the project must yield GHG reductions that are additional—

that is, beyond what will occur under business-as-usual operations and reductions not

otherwise mandated. "Adherence to the protocols ensures that the carbon reductions

generated by the project are real, permanent, quantifiable, verifiable, and enforceable."

An independent, qualified third-party must verify the GHG reduction achieved.14

6. CAP implementation and monitoring

The County will annually report the CAP's implementation, update the GHG

emissions inventory every two years, and every five years report findings from these

updates. "[I]f certain measures have proven successful, additional investment in those

measures may be made; or, conversely, if certain measures are proving to be more

14 Plaintiffs do not challenge T-4.1 or any other CAP GHG reduction measure.

19 difficult to achieve, then the County may redirect its efforts to other measures to achieve

overall GHG reduction targets."

7. Consistency with the CAP is the threshold of significance

CEQA requires public agencies to conduct an environmental review of

discretionary projects they approve and to prepare an EIR for any project that may have a

significant effect on the environment. (Pub. Resources Code, § 21151, subd. (a).) The

Guidelines encourage public agencies to develop "thresholds of significance" to assist in

determining whether a project's effect will be deemed significant. (Guidelines,

§ 15064.7.) " 'A threshold of significance is an identifiable quantitative, qualitative or

performance level of a particular environmental effect, non-compliance with which

means the effect will normally be determined to be significant by the agency and

compliance with which means the effect normally will be determined to be less than

significant.' " (California Building Industry Assn. v. Bay Area Air Quality Management

Dist. (2016) 2 Cal.App.5th 1067, 1072-1073.)

The Project's threshold of significance for GHG emissions is consistency with the

CAP:

"A proposed project would have a less than significant cumulatively considerable contribution to climate change impacts if it is found to be consistent with the County's Climate Action Plan; and, would normally have a cumulatively considerable contribution to climate change impacts if it is found to be inconsistent with the County's Climate Action Plan."

20 Details on how to achieve consistency with the CAP are in a separate document,

the Guidelines for Determining Significance, which also contains a checklist of CAP

GHG reduction measures, called the CAP Consistency Review Checklist (Checklist).

The Checklist implements a two-step process to determine consistency with the

CAP. The first step assesses whether a project is consistent with growth projections and

land use assumptions in the GPU. Those assumptions are the basis of the CAP's GHG

emissions projections.

Thus, if a project's land use is consistent with the GPU, then its GHG emissions

are already accounted for in the CAP's projections (because the projections assume

build-out under the GPU). In that event, the proposed project will achieve GHG

reduction targets by implementing CAP reduction measures.

In step two, the project applicant uses the Checklist to itemize and describe how

the project will implement applicable CAP GHG reduction measures.15 For example,

applicants for a residential development must indicate on the Checklist whether the

project will implement electric or alternatively-fueled water heating systems.

In-process GPAs that the County had not adopted by August 2017 are not included

in the CAP's GHG projections. Such projects achieve consistency with the CAP under

M-GHG-1, which we discuss next.

15 The CAP and Checklist also applies to projects requiring a land use and/or zoning amendment to the GPU, but which would result in an equivalent or less GHG-intensive project when compared to those allowed under the GPU.

21 E. The SEIR and M-GHG-1

1. The SEIR, in general

Twenty-one GPAs were in-process as of August 2017. The SEIR acknowledges

that in-process GPAs are reasonably foreseeable, could result in significant GHG impacts

and, therefore, are included in the SEIR's cumulative GHG impacts analysis. The SEIR

also recognizes that these and future GPAs are not accounted for in the CAP and may

impact the County's ability to meet CAP targets. To the extent in-process and future

GPAs would increase GHG emissions above projected CAP levels, their impact would be

significant (i.e., inconsistent with the CAP). The SEIR requires GPAs to use M-GHG-1

to mitigate GHG emissions to be within the threshold of significance, i.e., to not exceed

the CAP's GHG emission projections.

2. M-GHG-1, in general

M-GHG-1 "requires a project that increases density or intensity [of land use]

above what is allowed in the [GPU] to mitigate GHG emissions first through all feasible

onsite design features . . . ." Onsite design features may include "land use and design

features that reduce VMT [Vehicle Miles Traveled], promote transit oriented

development, promote street design policies that prioritize transit, biking, and walking,

and increase low carbon mobility choices, including improved access to viable and

22 affordable public transportation . . . ."16 If onsite design features are insufficient to fully

mitigate GHG emissions, then the project may use offsite mitigation, including in some

cases purchasing offset credits originating from projects anywhere in the world.17

Under M-GHG-1, the GPA project may mitigate GHG emissions under either of

two options: The first is called "No Net Increase." Under this option, "GPA project

applicants shall achieve no net increase in GHG emissions from additional density above

the 2011 GPU." For example, "if 400 residential units were allowed under the GPU and

a GPA proposes 500 residential units, the emissions for the 400 would be mitigated by

implementing CAP reduction measures, thereby reducing GHG impacts from the 400

units to below significance. GHG emissions for the 100 additional units must be

mitigated to zero through "onsite design features and mitigation measures and offsite

mitigation, including the purchase of carbon offset credits . . . ."

Option two is called "Net Zero." Under this option, GPA applicants shall reduce

all project GHG emissions to zero. Applicants shall first demonstrate compliance with

CAP measures before considering additional feasible onsite design features and

mitigation measures. Offsite mitigation, including purchase of carbon offset credits,

16 "Generally, vehicle miles traveled [VMT] is the most appropriate measure of transportation impacts. . . . VMT refers to the amount and distance of automobile travel attributable to a project." (Guidelines, § 15064.3, subd. (a).)

17 The text of M-GHG-1 is in Appendix 2 to this opinion.

23 would be allowed after all feasible onsite design features and mitigation measures have

been incorporated.

Common to both options is the goal to reduce to zero any increases in GHG

emissions over those projected in the CAP. If that occurs, CAP GHG emission forecasts

are unaffected by the GPA project. Accordingly, the GPA project would be consistent

with the CAP, and thus within the threshold of significance for GHG emissions.

F. CEQA Streamlining

To avoid repetition, wasted time, and unnecessary speculation, a lead agency may

"tier" environmental impact reports for a sequence of actions so that later EIRs

incorporate and build on the information in the previous CEQA document. (Pub.

Resources Code, §§ 21068.5; 21093, subd. (a).) Projects that are consistent with the

GPU and implement CAP GHG reduction measures may incorporate by reference the

CAP's cumulative GHG analysis. Conversely, projects that are consistent with the GPU

but do not implement CAP GHG reduction measures, as well as GPAs—will require a

project-level GHG analysis.

PROCEDURAL HISTORY18

A. Sierra Club Petition

After the County certified the SEIR, Sierra Club filed a petition for a writ of

mandate challenging the County's approval of the CAP, Significance Guidelines,

18 Procedural history predating the events described here is contained in Sierra Club I, supra, 231 Cal.App.4th at pp. 1156-1163 and Golden Door, supra, 27 Cal.App.5th at pp. 896-898.

24 threshold of significance for GHG emissions, and the SEIR. In the trial court, Sierra

Club asserted (1) the CAP and SEIR violated CEQA because M-GHG-1 allows

"in-County emissions from in-process and future GPAs to increase, provided there are

offsets purchased somewhere in the world, without demonstrating that such offsets will

be fully enforceable, verifiable, permanent, and additional"; (2) the County "gutted

Mitigation Measure CC-1.2 by establishing a target of "a mere 2 [percent] reduction in

emissions within the County from 2014 levels by 2020"; (3) the SEIR fails to analyze the

CAP's impact on the Regional Transportation Plan/Sustainable Communities Strategy

(RTP/SCS); (4) the County improperly failed to update its transportation modeling "using

data that included the recently approved GPAs, all reasonably expected GPAs, and the

approval of new residential development in far-flung rural areas"; (5) the SEIR failed to

analyze impacts from increased vehicle miles that would result from allowing "GPA

applicants to purchase GHG offsets"; (6) the SEIR fails to consider an alternative in

which "land use classifications and new GPA approvals" comport with and achieve

certain VMT reduction goals; (7) The SEIR fails to make good faith, reasoned responses

to public comments; (8) the SEIR fails to analyze environmental justice impacts; and

(9) the CAP and threshold of significance are inconsistent with the GPU.

B. Golden Door Petition and Consolidation

In a separate action, Golden Door sought injunctive and declaratory relief. Golden

Door alleged that it is the "owner and operator of an award-winning hospitality and

agricultural operation . . . situated on approximately 600 acres" in San Diego County.

Golden Door challenged the County's compliance with its General Plan and CEQA "to

25 the extent that the County has failed, in its newly adopted CAP, to adhere to requirements

to achieve 'reduction of community-wide (i.e., unincorporated County) and County

Operations greenhouse gas emissions' and other legal requirements."

In the trial court, Golden Door primarily asserted that the County violated CEQA

(and acted inconsistently with the GPU) by adopting a "program for carbon offset credits

('offsets') that would allow in-process and future ['GPAs'] to increase [GHGs] within the

County, in exchange for the purchase of offsets applicable to elsewhere in the

world . . . ." Golden Door asserted that the County "did not even attempt to quantify the

GHGs from the known, in-process GPAs, even though the 2018 CAP Project clearly

intended the offset program to apply to all GPAs." Golden Door also asserted that the

County improperly delegated and deferred feasibility findings in M-GHG-1 and failed to

adequately analyze: (1) VMT and other impacts resulting from implementing M-GHG-1;

(2) cumulative GHG impacts; (3) energy and environmental justice; and (4) smart growth

mitigation or alternatives for GPAs. Like Sierra Club, Golden Door also claimed that the

County failed to adequately respond to comments.

By stipulation, the trial court consolidated these two cases, along with a third

(Sierra Club v. County of San Diego, No. 37-2012-00101054-CU-TT-CTL) that had been

stayed.

After hearing, the trial court granted an (amended) peremptory writ of mandate,

ordering the County to set aside its approvals of the CAP, Guidelines for Determining

Significance, Checklist, certification of the SEIR, and "all attendant approvals in reliance

thereon . . . ." The trial court also entered a permanent injunction, providing: "During

26 review of [GHG] emissions impacts of development proposals on unincorporated County

lands under CEQA, including in the review of such impacts prior to the issuance of any

permits or entitlements for any General Plan amendment projects approved after

February 14, 2018, the County . . . shall not rely on Mitigation Measure M-GHG-1 . . . ."

Subsequently, the court entered a "final judgment" that also declared "that the February

2018 Climate Action Plan and the certification of the Final SEIR to the 2011 General

Plan Update Program EIR are legally inadequate and may not be used to provide the

basis for CEQA review of GHG impacts of development proposals in the unincorporated

County."

C. Appeals and Consolidation

The County filed a notice of appeal in the consolidated cases from "all judgments

and orders" including the writ of mandate and the permanent injunction. This court

consolidated the three appeals.

DISCUSSION

I.

THE CAP IS NOT INCONSISTENT WITH THE GPU

A. The Trial Court's Ruling

In the trial court, Plaintiffs asserted that the CAP is inconsistent with the GPU

because (1) M-GHG-1 is "part and parcel" of the CAP; and (2) the GPU requires

reducing in-County emissions; however, M-GHG-1 allows purchasing carbon offsets

"anywhere in the world." Noting the "paucity of offsets available within the County,"

27 Sierra Club asserted, "offsets are all but certain to come from outside the County," thus

violating a prime directive in the GPU.

The superior court agreed with Plaintiffs, stating, "[T]he County's General Plan

has consistently . . . stated it required in-County GHG reductions. However, M-GHG-1,

which is expressly incorporated into the 2018 CAP . . . allows essentially unlimited

increases in GHG within the County. In this respect, applicants proposing projects in the

County can meet their GHG mitigation requirements by purchasing offsets from

anywhere in the world . . . ."

The County contends the court erred because (1) M-GHG-1 is not a mitigation

measure of the CAP. Rather, M-GHG-1 is a mitigation measure in the SEIR and only

applies to GPAs; (2) the CAP is, therefore, not inconsistent with the GPU; and (3) GPAs

using M-GHG-1 would mitigate GHG emissions to be within CAP projections and,

therefore, be consistent with the GPU. We agree with the first and second points, and

find it unnecessary to consider the third in this context.

B. The Consistency Requirement

Land use decisions must be consistent with the policies expressed in a general

plan. (Citizens of Goleta Valley v. Board of Supervisors (1990) 52 Cal.3d 553, 570

(Citizens of Goleta Valley).) This doctrine is " 'the linchpin of California's land use and

development laws; it is the principle which infused the concept of planned growth with

the force of law.' " (Corona-Norco Unified School Dist. v. City of Corona (1993) 17

Cal.App.4th, 994.) However, " 'it is nearly, if not absolutely, impossible for a project to

be in perfect conformity with each and every policy set forth in the applicable plan. . . .

28 It is enough that the proposed project will be compatible with the objectives, policies,

general land uses and programs specified in the applicable plan.' " (Save Our Heritage

Organisation v. City of San Diego (2015) 237 Cal.App.4th 163, 186.)

C. The Standard of Review

Our role is the same as that of the trial court. (Naraghi Lakes Neighborhood

Preservation Assn. v. City of Modesto (2016) 1 Cal.App.5th 9, 19.) Review "is highly

deferential to the local agency, 'recognizing that "the body which adopted the general

plan policies in its legislative capacity has unique competence to interpret those policies

when applying them in its adjudicatory capacity. [Citations.] Because policies in a

general plan reflect a range of competing interests, the governmental agency must be

allowed to weigh and balance the plan's policies when applying them, and it has broad

discretion to construe its policies in light of the plan's purposes. [Citations.] A reviewing

court's role 'is simply to decide whether the [governing body] officials considered the

applicable policies and the extent to which the proposed project conforms with those

policies.' [Citation.]" [Citation.]' " (Friends of Lagoon Valley v. City of Vacaville (2007)

154 Cal.App.4th 807, 816.) "It is, emphatically, not the role of the courts to

micromanage these development decisions." (Sequoyah Hills Homeowners Assn. v. City

of Oakland (1993) 23 Cal.App.4th 704, 719 (Sequoyah Hills), italics omitted.)

D. The CAP is Not Inconsistent with the GPU

The CAP's GHG reduction measures apply only to the extent development is

consistent with land use allowed under the GPU. In such cases, the project's emissions

have already been accounted for in the CAP's projections. By incorporating the CAP's

29 GHG mitigation measures, a project will reduce its GHG emissions to levels consistent

with state GHG reduction targets.

In contrast, M-GHG-1 applies only to "in-process and future" GPAs—that is,

development involving density or intensity of land use above that allowed under the

GPU. To the extent such projects exceed CAP emission projections, their emissions are

not included in the CAP and, therefore, must be mitigated to zero to keep the County on

track to meet state targets. M-GHG-1 is intended to be that mitigation program. The

CAP explains this, stating:

"With incorporation of Mitigation Measure GHG-1, GPAs listed in the cumulative impact discussion of the Draft SEIR and all future GPAs that propose increased density/intensity above what is allowed in the General Plan will comply with the CAP and, therefore, will not interfere with the County's 2020 and 2030 GHG reduction targets or 2050 goal. General Plan Amendments would, therefore, comply with the threshold of significance, which is consistency with the CAP."

Thus, although the CAP refers to M-GHG-1, M-GHG-1 is not one of the CAP's

GHG reduction measures. Rather, the 26 local measures, none of which involve

purchasing carbon offsets outside the County—are the heart of the CAP. If the analysis

were to stop here, we would conclude that the CAP is fully consistent with the GPU

because the CAP analyzes GHG emissions resulting from buildout under the GPU.

Moreover, all of the CAP's GHG reduction measures will be implemented locally, thus

reducing GHG emissions in the County, which is also fully consistent with the GPU.

However, the CAP is not entirely independent from M-GHG-1. The CAP projects

future GHG emissions in the County. Those projections exclude emissions from

30 in-process GPAs and future GPAs. The CAP's projections exclude these foreseeable

GHG emissions on the assumption that such projects will mitigate their GHG emissions

to zero (or net zero) under M-GHG-1. The CAP states:

"General Plan Amendment projects currently in process . . . have not been included in the 2014 GHG . . . projections. . . . GPAs have the potential to result in a significant cumulative impact and also impact the ability of the County to meet its targets and goal. However, Mitigation Measure GHG-1 is provided to reduce the cumulative impact to less than significant. In addition, [M-GHG-1] would be required for all future GPAs . . . ."

As noted ante, M-GHG-1 allows mitigating in-County GHG emissions with offset

credits originating outside the County—even in another country. However, the GPU

expresses fundamental principles "designed to protect the County's unique and diverse

natural resources and maintain the character of its rural and semi-rural communities. It

reflects an environmentally sustainable approach to planning that balances the need for

adequate infrastructure, housing, and economic vitality, while maintaining and preserving

each unique community within the County, agricultural areas, and extensive open space."

(Italics added.) The GPU emphasizes local policies to reduce local GHG emissions:

"The General Plan takes steps to address the challenging issue of climate change by reducing GHG emissions, retaining and enhancing natural areas, improving energy efficiency, reducing waste, recycling, and managing water use. The General Plan will reduce GHG emissions primarily through minimizing vehicle trips and approving land use patterns that support increased density in areas where there is infrastructure to support it, increased opportunities for transit, pedestrians, and bicycles, and through green building and land development conservation initiatives. Policies also address adaptation to climate change, such as continued wildfire management and protection, monitoring flood hazards, and regional collaboration on biological preservation, water use and supply, and other areas of concern."

31 To the extent GPAs emit GHG in the County, but mitigate those impacts by

reducing emissions elsewhere, the CAP's projection of future GHG emission levels is not

entirely consistent with the GPU's focus on reducing in-County GHG emissions.19 The

issue, therefore, is whether this is enough to invalidate the CAP as being inconsistent

with the GPU.

A project need not conform perfectly to every general plan policy to be consistent

with the general plan. (Families Unafraid to Uphold Rural etc. County v. Board of

Supervisors (1998) 62 Cal.App.4th 1332, 1341.) The rule of general plan consistency is

that the project "must be 'compatible with the objectives, policies, general land uses, and

programs specified in' " the general plan. (Sequoyah Hills, supra, 23 Cal.App.4th at

pp. 717-718.) "[C]ourts accord great deference to a local governmental agency's

determination of consistency with its own general plan, recognizing that 'the body which

adopted the general plan policies in its legislative capacity has unique competence to

interpret those policies when applying them in its adjudicatory capacity. [Citations.]

Because policies in a general plan reflect a range of competing interests, the

governmental agency must be allowed to weigh and balance the plan's policies when

applying them, and it has broad discretion to construe its policies in light of the plan's

purposes. [Citations.] A reviewing court's role 'is simply to decide whether the [agency]

officials considered the applicable policies and the extent to which the proposed project

19 See post, section II (F) for additional discussion of the impact of M-GHG-1 on the

CAP.

32 conforms with those policies.' " (San Franciscans Upholding the Downtown Plan v. City

& County of San Francisco (2002) 102 Cal.App.4th 656, 677-678.)

Here, GPU policies must also be construed in light of science. "[T]he global

scope of climate change and the fact that carbon dioxide and other greenhouse gases,

once released into the atmosphere, are not contained in the local area of their emission

means that the impacts to be evaluated are also global rather than local." (Center for

Biological Diversity, supra, 62 Cal.4th at pp. 219-220.) Thus, reducing or eliminating

GHG emissions anywhere is a benefit.

Although the CAP is not perfectly in tune with the GPU, and in light of the highly

deferential standard of review, we conclude the court erred in determining that the CAP

is inconsistent with GPU policies. A "guiding principle" in the GPU is to "reduce

greenhouse gas emissions that contribute to climate change." The GPU recognizes that

the "sources, impacts, and solutions to climate changes are complex." The GPU contains

a policy to "reduce GHG emissions primarily through minimizing vehicle trips and

approving [sustainable] land use patterns . . . ." (Italics added.) The GPU provides that

the "primary opportunities to reduce air quality pollutants and GHG emissions are in the

urbanized areas of the County where there are land use patterns that can best support the

increased use of transit and pedestrian activities . . . ." (Italics added.)

Plaintiffs' argument that the CAP is inconsistent with these goals would require

replacing "primarily" with "exclusively." Moreover, the CAP is consistent with the GPU

by providing measures to reduce VMT, recognizing that such measures are necessary to

achieve the 2030 target. "[P]roposed transportation measures in the CAP focus on

33 reducing VMT through improved design of development, infrastructure improvements,

travel demand management programs, parking code revisions, and alternative fuel use."

"Several GHG reduction measures focus on reducing the number and length of single-

occupancy vehicle trips (measures T-1.1, T-1.2, and T-1.3) and expanding alternative

transportation opportunities (measures T-2.1, T-2.2, T-2.3, and T-2.4)." CAP measure

T-2.1 reduces VMT by improving roadway segments, intersections, and bikeways to

encourage pedestrian and cyclist trips. Another reduces VMT by encouraging alternative

work schedules and telecommuting.

Additionally, the GPU provides that the CAP shall contain a "baseline inventory"

of GHG emissions from all sources, GHG emissions reduction targets and deadlines, and

enforceable GHG emissions reduction measures. The CAP complies by containing

(1) a baseline inventory, (2) GHG reduction targets and deadlines, and 26 GHG reduction

measures.

The GPU also contains a policy to reduce in-County and County operations GHG

emissions to meet legislative targets. The CAP is consistent with this goal by adopting

per capita reductions suggested by CARB to meet 2030 and 2050 targets.

To support a contrary result, Plaintiffs cite Spring Valley Lake Assn. v. City of

Victorville (2016) 248 Cal.App.4th 91. There, a city's general plan required all new

commercial development to generate electricity onsite to the maximum extent feasible.

(Id. at p. 98.) The EIR for a proposed Walmart stated the project would be solar ready,

and should a determination be made in the future that photovoltaic panels can deliver

power there at a reasonable cost, Walmart and the city would negotiate adding solar

34 energy-generating facilities to the project. (Ibid.) On appeal, this court affirmed the trial

court's finding that the project was not consistent with the general plan because the city

"effectively found there was no extent to which it would be feasible to require the project

to generate electricity onsite" and "there is no evidence in the record to support such a

finding." (Id. at pp. 99-100.) In contrast here, however, the SEIR's finding that

implementing the CAP would not be inconsistent with the 2011 GPU is supported by

substantial evidence.

E. It is Unnecessary to Decide Whether M-GHG-1 Projects Are Consistent with the GPU

In a related argument, Plaintiffs contend that GPAs using M-GHG-1 will be

inconsistent with the GPU because M-GHG-1 allows in-County emissions to be

mitigated with out-of-County offsets. It is unnecessary to decide this issue. As explained

post, M-GHG-1 is not CEQA-compliant. Because M-GHG-1 fails on these grounds, it is

unnecessary to decide whether M-GHG-1 is invalid for other reasons. (See Communities

for a Better Environment v. City of Richmond (2010) 184 Cal.App.4th 70, 101-102 (CBE)

[appellate court not required to address additional alleged defects that may be addressed

in a completely different and more comprehensive manner upon subsequent CEQA

review following remand].)

35

II.

M-GHG-1 VIOLATES CEQA

A. The Trial Court's Ruling

The superior court determined that M-GHG-1 violates CEQA by (1) "allow[ing]

the use of offsets purchased anywhere on the planet, with no limit on geographic scope or

duration (and no temporal or cumulative limit)"; (2) containing an "illusory" geographic

priority because only one offset project exists in the County; and (3) requiring offsets be

purchased from CARB-approved registries is "not remotely similar to the CARB

program." Elaborating, the trial court noted that cap-and-trade offsets are generally

limited to those occurring in the United States and may only be used to meet up to

8 percent of a participant's annual compliance obligations. However, M-GHG-1 has

neither limitation. The court also stated there is no evidence that out-of-County offsets

will be enforceable, verifiable, and of sufficient duration. The court further determined

that M-GHG-1 lacks "standards or criteria" for achieving the Director's " 'satisfaction' "

and for determining whether a registry is sufficiently "reputable" to substitute for the

identified registries.

B. CEQA Overview

" 'The foremost principle under CEQA is that the Legislature intended the act "to

be interpreted in such manner as to afford the fullest possible protection to the

environment within the reasonable scope of the statutory language.' " [Citations.] 'With

narrow exceptions, CEQA requires an EIR whenever a public agency proposes to

approve or to carry out a project that may have a significant effect on the environment.

36 [Citations.]' The basic purpose of an EIR is to 'provide public agencies and the public in

general with detailed information about the effect [that] a proposed project is likely to

have on the environment; to list ways in which the significant effects of such a project

might be minimized; and to indicate alternatives to such a project.' [Citations.] 'Because

the EIR must be certified or rejected by public officials, it is a document of

accountability. If CEQA is scrupulously followed, the public will know the basis on

which its responsible officials either approve or reject environmentally significant action,

and the public, being duly informed, can respond accordingly to action with which it

disagrees.' [Citation.] The EIR "protects not only the environment but also informed

self-government.' " (Sierra Club v. County of Fresno (2018) 6 Cal.5th 502, 511-512

(Sierra Club).) " ' "The EIR is the heart of CEQA," and the integrity of the process is

dependent on the adequacy of the EIR.' " (Rialto Citizens for Responsible Growth v. City

of Rialto (2012) 208 Cal.App.4th 899, 924.)

C. The Standard of Review

The parties disagree about the applicable standard of review. The County

contends the CEQA issues are reviewed for abuse of agency discretion, and that the

substantial evidence standard governs review of the County's "factual findings,

conclusions, and determinations." However, citing primarily Sierra Club, supra, 6

Cal.5th 502, Plaintiffs contend "[d]e novo is the correct standard of review" for the

CEQA claims.

The applicable standard of review is more nuanced. "[T]he appellate court

reviews the agency's action, not the trial court's decision; in that sense appellate judicial

37 review under CEQA is de novo." (Vineyard Area Citizens for Responsible Growth, Inc.

v. City of Rancho Cordova (2007) 40 Cal.4th 412, 427.)

The County's determinations as lead agency are reviewed for abuse of discretion.

(Sierra Club, supra, 6 Cal.5th at p. 512.) " '[A]n agency may abuse its discretion under

CEQA either by failing to proceed in the manner CEQA provides or by reaching factual

conclusions unsupported by substantial evidence.' " (Banning Ranch Conservancy v. City

of Newport Beach (2017) 2 Cal.5th 918, 935 (Banning Ranch).)

And within this abuse of discretion standard, review varies depending on the issue

involved. " 'While we determine de novo whether the agency has employed the correct

procedures, "scrupulously enforc[ing] all legislatively mandated CEQA requirements"

[citation], we accord greater deference to the agency's substantive factual conclusions. In

reviewing for substantial evidence, the reviewing court "may not set aside an agency's

approval of an EIR on the ground that an opposite conclusion would have been equally or

more reasonable," for, on factual questions, our task "is not to weigh conflicting evidence

and determine who has the better argument." ' " (Sierra Club, supra, 6 Cal.5th at p. 512.)

In Sierra Club, the California Supreme Court summarized these principles as

follows: (1) An agency has considerable discretion in deciding the manner of discussing

potentially significant effects in an EIR. (2) However, a reviewing court must determine

whether that discussion comports with an EIR's intended function. (3) This review is not

solely a matter of discerning whether there is substantial evidence to support the agency's

factual conclusions. (Sierra Club, supra, 6 Cal.5th at pp. 515-516.) For example, there

are " 'instances where the agency's discussion of significant project impacts may

38 implicate a factual question that makes substantial evidence review appropriate,' such as

an agency's decision to use a particular methodology. [Citation.] 'But whether a

description of an environmental impact is insufficient because it lacks analysis or omits

the magnitude of the impact is not a substantial evidence question.' [Citation.] Where

the ultimate inquiry is whether an EIR omits material necessary to reasoned

decisionmaking and informed public participation, the inquiry is predominantly legal and,

'[a]s such, it is generally subject to independent review.' " (Chico Advocates for a

Responsible Economy v. City of Chico (2019) 40 Cal.App.5th 839, 846-847.)

"The ultimate inquiry . . . is whether the EIR includes enough detail 'to enable

those who did not participate in its preparation to understand and to consider

meaningfully the issues raised by the proposed project.' " (Sierra Club, supra, 6 Cal.5th

at p. 516.) "Generally, that inquiry is a mixed question of law and fact subject to de novo

review, but to the extent factual questions . . . predominate, a substantial evidence

standard of review will apply." (South of Market Community Action Network v. City and

County of San Francisco (2019) 33 Cal.App.5th 321, 330-331 (South of Market).) " 'A

prejudicial abuse of discretion occurs if the failure to include relevant information

precludes informed decisionmaking and informed public participation, thereby thwarting

the statutory goals of the EIR process.' " (Id. at p. 331.)

With these principles in mind, we turn to the CEQA issues.

39 D. M-GHG-1 Violates CEQA Because Its Performance Standard is Unenforceable

1. Introduction

A mitigation measure is a change that would reduce or minimize the project's

significant adverse environmental impact. (No Slo Transit, Inc. v. City of Long Beach

(1987) 197 Cal.App.3d 241, 256.) " 'Mitigating conditions are not mere expressions of

hope.' " (Sierra Club I, supra, 231 Cal.App.4th at p. 1167.) They must be enforceable

through permit conditions, agreements, or other legally-binding instruments. (Pub.

Resources Code, § 21081.6, subd. (b); Guidelines, § 15126.4, subd. (a)(2).)

Mitigation measures for GHG emissions may include "[o]ffsite measures,

including offsets that are not otherwise required." (Guidelines, § 15126.4, subd. (c)(3).)

The parties agree that offsets "can be a valuable GHG mitigation strategy" if "[p]roperly

restricted" with "verified offsets." However, as the superior court remarked, "the devil is

in the details."

Under section 38562, subdivision (d)(1) and (2), cap-and-trade offset credits may

be issued only if the emission reduction achieved is "real, permanent, quantifiable,

verifiable, enforceable, and additional to any GHG emission reduction otherwise required

by law or regulation, and any other GHG emission reduction that otherwise would

occur."

" 'Real' means . . . that GHG reductions . . . result from a demonstrable action or

set of actions, and are quantified using appropriate, accurate, and conservative

methodologies that account for all GHG emissions sources, GHG sinks, and GHG

40 reservoirs within the offset project boundary and account for uncertainty and the potential

for activity-shifting leakage and market-shifting leakage."20 (Cal. Code Regs., tit. 17,

§ 95802.) " 'Permanent' means . . . that GHG reductions . . . are not reversible, or when

GHG reductions . . . may be reversible, that mechanisms are in place to replace any

reversed GHG emission reductions . . . to ensure that all credited reductions endure for at

least 100 years." (Ibid.) " 'Quantifiable' means . . . the ability to accurately measure and

calculate GHG reductions . . . relative to a project baseline in a reliable and replicable

manner for all GHG emission sources . . . ." (Ibid.) " 'Verifiable' means that an Offset

Project Data Report assertion is well documented and transparent such that it lends itself

to an objective review by an accredited verification body." (Ibid.) " 'Additional'

means . . . greenhouse gas emission reductions or removals that exceed any greenhouse

gas reduction or removals otherwise required by law, regulation or legally binding

mandate, and that exceed any greenhouse gas reductions or removals that would

otherwise occur in a conservative business-as-usual scenario." (Cal. Code Regs., tit. 17,

§ 95802.)

20 GHG sink means "a physical unit or process that removes a GHG from the atmosphere." (Cal. Code Regs., tit. 17, § 95802.) GHG reservoir means "a physical unit or component of the biosphere, geosphere, or hydrosphere with the capability to store, accumulate, or release a GHG removed from the atmosphere by a GHG sink or a GHG captured from a GHG emission source." (Ibid.) Leakage is an unintended increase in GHG emissions caused by a project. " 'Market-shifting leakage,' in the context of an offset project, means increased GHG emissions or decreased GHG removals outside an offset project's boundary due to the effects of an offset project on an established market for goods or services." (Id., § 95102.)

41 The text of M-GHG-1 incorporates section 38562, subdivision (d)(1) by reference

by stating, "Carbon offset credits must be purchased through [certain named registries or

through] . . . any other reputable registry or entity that issues carbon offsets consistent

with . . . section 38562(d)(1) . . . ."21 Moreover, to demonstrate that M-GHG-1 is

CEQA-compliant, the County invites comparison between M-GHG-1 and CARB-issued

offset credits under cap-and-trade. Although conceding at oral argument that there are

"some differences" between cap-and-trade offset credits and offset credits under

M-GHG-1, the County contends cap-and-trade and M-GHG-1 are "substantially similar."

Specifically, the County asserts that M-GHG-1 will be "effective and enforceable"

because M-GHG-1 requires offsets to be purchased from registries that "meet the

stringent requirements of . . . section 38562, subdivision (d)(1)."

Accordingly, we compare and contrast the "stringent requirements" in M-GHG-1

with those governing CARB offset credits under cap-and-trade.

2. Cap-and-trade offset protocols

The value of any offset depends on whether GHG emission reduction has

occurred. "[U]nlike the produce at the farmer's market, we can't examine the [GHG

offset] product to determine its value. Not only are emission reductions invisible, they

actually didn't happen. So to have confidence in their value, we need a reliable and

accurate picture of what would have happened, as well as what actually happened."

21 The County asserts that CEQA does not "import Health and Safety Code standards for Assem. Bill No. 32 . . ." It is unnecessary to address that issue because M-GHG-1 self-imposes these requirements.

42 (California Air Pollution Control Officers Association, Quantifying Greenhouse Gas

Mitigation Measures (2010), p. 22 (CAPCOA Quantifying), italics in original.)

"Protocols are the formalized procedures for accounting for credits that ensure the

credits are an accurate and reliable representation of emission reductions that actually

occurred." (CAPCOA Quantifying, supra, at p. 22.) Protocols " 'qualify and quantify

GHG destruction, ongoing GHG reductions or GHG removal enhancements achieved by

an offset project.' " (Our Children's Earth Foundation v. State Air Resources Bd. (2015)

234 Cal.App.4th 870, 879 (Our Children's).)

Under cap-and-trade, an offset project must use a CARB-approved "Compliance

Offset Protocol" (CARB Protocol). (Cal. Code Regs., tit. 17, § 95973, subd. (a)(1).)

CARB Protocols are designed to "ensure that the reductions are quantified accurately,

represent real GHG emissions reduction, and are not double-counted within the system."

More specifically, a CARB Protocol must:

"(1) Accurately determine the extent to which GHG emission reductions and GHG removal enhancements are achieved by the offset project type;

"(2) Establish data collection and monitoring procedures relevant to the type of GHG emissions sources, GHG sinks, and GHG reservoirs for that offset project type[];

"(3) Establish a project baseline that reflects a conservative estimate of business-as-usual performance or practices for the offset project type;

"(4) Account for activity-shifting leakage and market-shifting leakage for the offset project type, unless the Compliance Offset Protocol stipulates eligibility conditions for use of the Compliance Offset Protocol that eliminate the risk of activity-shifting and/or market-shifting leakage;

43 "(5) Account for any uncertainty in quantification factors for the offset project type;

"(6) Ensure GHG emission reductions and GHG removal enhancements are permanent;

"(7) Include a mechanism to ensure permanence of GHG removal enhancements for sequestration offset project types;

"(8) Establish the length of the crediting period pursuant to [California Code of Regulations, title 17,] section 95972[, subdivision] (b) for the relevant offset project type; and

"(9) Establish the eligibility and additionality of projects using standard criteria, and quantify GHG reductions and GHG removal enhancements using standardized baseline assumptions, emission factors, and monitoring methods." (Cal. Code Regs., tit. 17, § 95972.)

A CARB Protocol must also specify the project's geographic boundary.

Generally, that boundary must be within the United States or its territories. (Cal. Code

Regs., tit. 17, § 95972, subd. (c).)22 Also, the project must employ procedures specified

in the CARB Protocol "for monitoring measurements and project performance . . . ." (Id.,

§ 95976, subd. (a).)

There are currently six CARB Protocols. (Cal. Code Regs., tit. 17, § 95975,

subd. (e).) Each is from a distinct economic sector outside the coverage of cap-and-trade.

(Ibid.) For example, the livestock protocol authorizes offset credits for projects that

reduce methane emissions. (Our Children's, supra, 234 Cal.App.4th at p. 880.)

22 In this respect, the County's assertion at oral argument that cap-and-trade has no "geographic preferences" is incorrect.

44 Cap-and-trade offsets must also be additional. This means that the offset project

must "exceed any [GHG] reduction or removals otherwise required by law, regulation, or

legally binding mandate." The offset must also exceed what would have otherwise

occurred "in a conservative business-as-usual scenario." (Health & Saf. Code, § 38562,

subd. (d)(1) & (2); Cal. Code. Regs., tit. 17, § 95802, subd. (a)(4).)23 For example, the

ozone depleting substances protocol excludes destruction of such substances by the

United States government because such " 'is common practice and considered business-

as-usual. . . .' " (Our Children's, supra, 234 Cal.App.4th at p. 881.)

A CARB Protocol must " '[e]stablish [] the eligibility and additionality of projects

using standard criteria, and quantif[y] GHG reductions and GHG removal enhancements

using standardized baseline assumptions, emission factors, and monitoring methods.'

[Citation.] Furthermore, a specific project may qualify for an offset credit only by

meeting both the additionality requirements set forth in the regulation and any

additionality requirements in the applicable [CARB] [P]rotocol." (Our Children's, supra,

234 Cal.App.4th at p. 878.)

23 " 'Conservative' means . . . utilizing project baseline assumptions, emission factors, and methodologies that are more likely than not to understate net GHG reductions or GHG removal enhancements for an offset project to address uncertainties affecting the calculation or measurement of GHG reductions or GHG removal enhancements." (Cal. Code Regs., tit. 17, § 95802, subd. (a)(77).) " 'Business-as-Usual Scenario' means the set of conditions reasonably expected to occur within the offset project boundary in the absence of the financial incentives provided by offset credits, taking into account all current laws and regulations, as well as current economic and technological trends.' " (Id., subd. (a)(43).)

45 CARB Protocols are regulatory documents. Therefore, CARB must "provide

public notice of and opportunity for public comment prior to approving any [CARB]

Protocols . . . ." (Cal. Code Regs., tit. 17, § 95971, subd. (a).)

After issuing offset credits, CARB may invalidate them if newly discovered

information shows the Protocol was noncompliant. (Cal. Code Regs., tit. 17, § 95985,

subd. (c).)

Offset projects in foreign countries present additional concerns. "With domestic

offsets, the offset developer and capped source purchaser are within [CARB's]

jurisdiction. Regulations have been adopted that assure that if an offset is false, fails or

otherwise is inadequate that [CARB] can take enforcement action.' [CARB] can rely

upon existing monitoring, inspections and other tools that an enforcement agency has

available to it. An international offset in a developing country is inevitably dependent

upon the host country or third parties to validate the activities giving rise to the offset.

Corruption at any stage in the development of the offset, from the initial reporting to the

verification and monitoring will undermine the offset." (Alan Ramo, The California

Offset Game: Who Wins and Who Loses, 20 Hastings W.-Nw. J. Envt'l L. & Pol'y 109,

147 (2014) (Ramo Offset).)

California's cap-and-trade program includes several additional requirements for

out-of-state and foreign offsets. This process is called "linkage." (Gov. Code, § 12894,

subd. (e).)

Before linking with another jurisdiction's offset program, CARB must notify the

Governor, who has 45 days in which to consider advice from the Attorney General, and

46 make (or decline to make) the following findings that are submitted to the Legislature:

(1) The other jurisdiction's GHG emissions program must be "equivalent to or stricter

than" California's program; (2) California must retain the ability to enforce Assem. Bill

No. 32 requirements against any entity subject to regulation under those statutes, and

against any entity located within the other jurisdiction to the maximum extent permitted

under the United States and California Constitutions; (3) the other jurisdiction must have

equivalent or stricter enforcement powers; and (4) the proposed linkage does not impose

any liability on California. (Gov. Code, § 12894, subds. (f) & (g).)24

3. Registries

An Offset Project Registry (Registry) is "an entity that . . . is approved by [C]ARB

that lists offset projects, collects Offset Project Data Reports, facilitates verification of

Offset Project Data Reports, and issues registry offset credits for projects being

implemented using a CARB Protocol." (Cal. Code Regs., tit. 17, § 95802.) However, to

obtain a CARB offset credit, it is not enough for a Registry to issue credit. CARB alone

determines whether a registry offset qualifies as a compliance instrument. (Id., §§ 95802

[defining registry offset credit], 95981.1 [process for issuing CARB offset credits].)

4. M-GHG-1 is not equivalent to cap-and-trade offsets

The County contends that M-GHG-1 is "substantially similar" to the offset

program authorized under cap-and-trade. Specifically, the County asserts that like offsets

24 Sierra Club's request for judicial notice of CARB's website discussing linkage is denied as irrelevant. (SDOG, supra, 13 Cal.App.5th at p. 90, fn. 8.)

47 under cap-and-trade, M-GHG-1 requires offsets "be purchased from a registry approved

by [C]ARB or one that meets section 38562[, subdivision (d)(1)]." The County argues

that this is a "sufficient safeguard[]" to "ensure credits purchased pursuant to M-GHG-1

are real, permanent, verifiable, and enforceable."

However, M-GHG-1 is materially different from Assem. Bill No. 32 compliant

cap-and-trade offsets in several key respects. Under M-GHG-1, offsets must be

purchased through "(i) a CARB-approved registry, such as the Climate Action Reserve,

the American Carbon Registry, and the Verified Carbon Standard, (ii) any registry

approved by CARB to act as a registry under the state's cap-and-trade program,

(iii) through the CAPCOA GHG Rx and SDAPCD, or (iv) if no registry is in existence as

identified . . . above, then any other reputable registry or entity that issues carbon offsets

consistent with . . . section 38562 [subdivision] (d)(1), to the satisfaction of the

Director . . . ."25 At oral argument, the County explained that it is "through the use of

those registries that the protocol gets applied." But M-GHG-1 says nothing about the

protocols that the identified registries must implement. Therefore, implicit in the

County's argument is that if the registry administering the offset is CARB-approved, then

for that reason alone, necessarily the GHG emissions reduction protocol administered by

that agency is also Assem. Bill No. 32 compliant, thereby ensuring the validity of the

offset credit claimed. However, this assumption is incorrect.

25 CAPCOA GHG Rx is the California Air Pollution Control Officers Association Greenhouse Gas Reduction Exchange. APCD is the Air Pollution Control District.

48 Unlike M-GHG-1, under cap-and-trade, it is not enough that the registry be

CARB-approved. Equally important, the protocol itself must be CARB-approved. (Cal.

Code Regs., tit. 17, § 95970, subd. (a)(1) & (2).)26 This distinction is significant because

some offset protocols administered by CARB-approved registries are not Assem. Bill No.

32 compliant. Indeed, CARB has stated that offset protocols developed by CARB-

approved registries (including registries named in M-GHG-1) do not by that fact alone

meet the offset criteria in Assem. Bill No. 32:

"Voluntary offset programs such as the American Carbon Registry, Climate Action Reserve, Verified Carbon Standard, and others may submit protocols to [C]ARB for review. However, regardless of how the voluntary protocols are developed, [C]ARB staff must determine whether the voluntary protocol should be developed for use in the Cap-and-Trade Program and if so, to conduct its own rulemaking process under the Administrative Procedure Act. . . . This process ensures that any voluntary protocol . . . demonstrates the resulting reductions meet the offset criteria in [Assem. Bill No. 32] . . . .

"Protocols developed by the voluntary programs are not Compliance Offset Protocols as they are not developed through a rulemaking process, may not meet the [Assem. Bill No. 32] and Cap- and-Trade Regulation criteria, and were not approved by [CARB]." (Italics added.)

Furthermore, before approving a protocol, CARB subjects the proposed offset

protocol to public notice, a comment period, and a public hearing. (Cal. Code Regs.,

tit. 17, §§ 95970, subd. (a)(2), 95971, subd. (a).) CARB also requires that emission

reductions for offset credit be from sources not already covered by cap-and-trade. For

26 "A registry offset credit must . . . [r]esult from the use of a Compliance Offset Protocol . . . ." (Cal. Code Regs., tit. 17, § 95970, subd. (a)(2).)

49 example, CARB would not approve an offset protocol for installing solar panels because

electricity generation is already covered under cap-and-trade.

The CARB Protocols are the heart of cap-and-trade offsets—but the word

"protocol" is not even mentioned in M-GHG-1. Contrary to the County's contention,

M-GHG-1 is not equivalent to cap-and-trade offset programs because M-GHG-1 does not

require the protocol itself to be consistent with CARB requirements under title 17, section

95972, subdivision (a)(1)-(9) of the California Code of Regulations, quoted ante. For

example, CARB will not approve a protocol unless its GHG reductions are permanent.

(Id., § 95970, subd. (a)(1).) If the project is to sequester carbon (e.g., planting trees), the

protocol must ensure that the GHG will not be released for 100 years. M-GHG-1 is

deficient because it has no such safeguards.

Under cap-and-trade, legislative safeguards seek to ensure that out-of-state offsets

reflect genuine GHG reductions. For example, CARB may approve out-of-state offsets

only if the Governor makes findings to ensure the linked jurisdiction's offsets are

genuine, verifiable, and enforceable under law that is at least as strict and enforceable as

is California law. (Gov. Code, § 12894, subd. (f).) However, M-GHG-1 has no such

restrictions. The only M-GHG-1 limit on mitigating with international offsets is the

Director's unilateral decision that offsets are not feasibly available within (1) the

unincorporated county; (2) the County; (3) California; and (4) the United States. The

fundamental problem, unaddressed by M-GHG-1, is that the County has no enforcement

authority in another state, much less in a foreign country. M-GHG-1 does not require a

50 finding that an out-of-state offset site has laws at least as strict as California's with respect

to ensuring the validity of offsets.

At oral argument, the County asserted that the "registries" would be the County's

enforcement mechanism to ensure the validity of offsets originating in foreign countries.

This argument fails, however, because it is premised on the assumption that the registry's

protocol is Assem. Bill No. 32 compliant—and as explained ante, M-GHG-1 does not

require use of an Assem. Bill No. 32 compliant protocol.

Moreover, nothing other than the Director's determination of feasibility limits a

GPA applicant from obtaining up to 100 percent of its GHG emission reductions through

M-GHG-1 offsets. This includes offset projects occurring anywhere in the world. In

sharp contrast, cap-and-trade offsets cannot exceed 8 percent of an entity's entire

compliance obligation. (Cal. Code Regs., tit. 17, § 95854, subd. (b).)27

The relative ease with which GPAs might obtain offset credits originating in

foreign countries under M-GHG-1 is particularly concerning because "[i]n a developing

country where one relies upon records that may not exist, and testing technology that may

be inadequate or fraudulent, it can be difficult if not impossible" to verify GHG

reductions. (Ramo Offset, supra, 20 Hastings W.-Nw. J. Envt'l L. & Pol'y at p. 121.)

"Beyond these challenges is the issue of what would have happened anyway. A

developing country is so named because it is economically underdeveloped and is

27 We express no opinion on whether 8 percent is also the CEQA limit. That issue is not before us.

51 hopefully making economic and social progress. In that climate, how does one

distinguish between an emission reduction that would have happened anyway and one

that is happening only or in part because of the encouragement of the offset program and

the potential to sell a credit for a profit?" (Ibid.) "Corruption also presents

challenges . . . . [As of 2011], [t]here [were] . . . carbon reduction projects either certified

or under development in Ethiopia, Nicaragua, the Philippines, Kenya, and Venezuela.

Yet, Transparency International's Global Corruption Report 2009 rates Ethiopia as the

126th most corrupt country out of 180 countries, Nicaragua as the 134th, the Philippines

as the 141st, Kenya as the 147th, and Venezuela as the 158th." (Brian Joseph McFarland,

Carbon Reduction Projects and the Concept of Additionality (2011) 11 Sustainable Dev.

L. & Pol'y 15, 16 (McFarland), fn. omitted.)

There is another significant deficiency in M-GHG-1. Under cap-and-trade, GHG

emission reductions must be additional "to any greenhouse gas emission reduction

otherwise required by law or regulation, and any other greenhouse gas emission reduction

that otherwise would occur." (§ 38562, subd. (d)(2).) "Additionality is an important

requirement because if non-additional (i.e., 'business-as-usual') projects are eligible for

carbon [offset] . . . then the net amount of greenhouse gas emissions will continue to

increase and the environmental integrity of carbon reduction projects will be called into

question." (McFarland, supra, 11 Sustainable Dev. L. & Pol'y at p. 15.) For example,

CARB will not approve a protocol that "includes technology or GHG abatement practices

that are already widely used." Moreover, "[t]o assess if a specific GHG mitigation

method may have 'otherwise occurred,' " CARB will determine "if that method is

52 common practice in the geographic area in which the proposed [CARB Protocol] is

applicable."

Although additionality is "a critical component of any environmental market" it is

"often seen as expensive [and] onerous. . . ." (Karen Bennett, Additionality: The Next

Step for Ecosystem Service Markets (2010) 20 Duke Envt'l. L. & Pol'y F. 417, 419.)

Perhaps this explains why M-GHG-1 seemingly goes out of its way to not require

additionality.

Under M-GHG-1, the Director may approve offsets issued by any "reputable

registry or entity that issues carbon offsets consistent with . . . section 38562[,

subdivision] (d)(1)." The County asserts this reference to section 38562 ensures that

offset protocols administered under M-GHG-1 will be substantially similar to Assem. Bill

No. 32 compliant offsets. However, subdivision (d)(1) of section 38562 does not require

that offsets be additional. Additionality is required under the next subdivision [(d)(2)] in

section 38562, which provides in part:

"Any regulation adopted by [CARB] . . . shall ensure all of the following: [¶] . . . [¶] (2) . . . the reduction is in addition to any greenhouse gas emission reduction otherwise required by law or regulation, and any other greenhouse gas emission reduction that otherwise would occur." (§ 38562, subd. (d)(2).)

Although M-GHG-1 cites subdivision (d)(1) of section 38562, it is silent with

respect to subdivision (d)(2). And there is nothing else in M-GHG-1's text that requires

53 additionality.28 At oral argument, when asked to identify the language in M-GHG-1 that

requires "additionality," the County's lawyer cited a portion of the SEIR that states, "One

carbon offset credit represents the past reduction or sequestration of one metric ton of

carbon dioxide equivalent that is 'not otherwise required' (CEQA Guidelines section

15126.4 [subdivision] (c)(3))." (Italics added.) Later, however, counsel correctly

conceded that "not otherwise required" is not in the text of M-GHG-1. Rather, it is in a

prefatory section of the SEIR about greenhouse gas emissions, prior to the text of

M-GHG-1 itself.

In comments to the DSEIR, Golden Door's attorneys called the County's attention

to these problems. In response, the County did not claim that additionality was not

required. Rather, the County asserted that M-GHG-1 offsets would be additional by

"adher[ing] to the applicable protocol, as detailed in SEIR Appendix B." In its reply

brief, the County makes the same assertion, stating: "Appendix B to the SEIR contains

nearly 3,000 pages of offset protocols that the registries listed in M-GHG-1 use to ensure

that offsets meet rigorous standards showing they are . . . additional, and verifiable . . . ."

The problem with this argument is that Appendix B itself states that it does not

apply to M-GHG-1. Rather, Appendix B applies to CAP reduction measure T.-4.1.

Appendix B is entitled "Range of Direct Investment Protocols." (Italics added.) The

28 In its reply brief, the County glosses over this deficiency by asserting that under M-GHG-1, "a registry must meet the requirement of . . . section § [sic] 38562 . . . ." However, the text of M-GHG-1 invokes only subdivision (d)(1) of that statute, not subdivision (d)(2).

54 direct investment program is GHG reduction measure T-4.1 in the CAP. As explained

ante, under T-4.1, the County may invest in projects in the County that reduce or

eliminate in-County GHG emissions. The SEIR explains, "Appendix B of this Draft

SEIR provides a range of protocols that may be applied to County direct investment

projects to implement GHG Reduction Measure T-4.1." Elsewhere in its response to

comments, the County similarly states, "Appendix B provides support for the County's

local direct investment projects through CARB-approved protocols. . . . Appendix B

applies only to how the County will ensure tracking and enforceability of GHG Reduction

Measure T-4.1." (Italics added.) In response to another comment, the County added,

"The performance-based protocols listed in CAP SEIR Appendix B will be used to

develop project-level detail for implementing GHG Reduction Measure T-4.1 . . . ." At

oral argument, the County had no response to this point.

Thus, although nothing appears to preclude a GPA project from using an

Appendix B protocol as part of its M-GHG-1 mitigation—nothing in M-GHG-1 requires

it. By insisting that M-GHG-1 requires additionality because it requires GPAs to use

Appendix B protocols, the County actually highlights one of M-GHG-1's most significant

flaws—offset credits under M-GHG-1 need not be additional.29

29 In this litigation, Plaintiffs have not challenged any of the Appendix B protocols. Therefore, for future reference they are: CAPCOA GHG Rx protocols: (a) Biomass Waste for Energy Project (2013); (b) Coastal Wetland Creation Version 1.0 (2016); (c) Compost Additions to Grazed Grasslands (2014); (d) Forestry Protocol #1 (2013); (e) Forestry Protocol # 2 (2013);

55 5. The County's arguments that M-GHG-1 is enforceable lack merit

The County also contends that M-GHG-1 is effective and enforceable because it

"perfectly conforms" to a "discussion draft" on carbon offsets prepared by the Governor's

Office of Planning and Research (OPR). However, this document is not part of the

record and we deny the County's judicial notice request. (Moore v. City of Los Angeles

(2007) 156 Cal.App.4th 373, 386 [review of administrative proceeding is limited to

matters contained within the administrative record].)

In any event, the OPR document on its face states it is a "draft" containing "initial

thoughts." To the extent the document has any probative value, it states that offsets are a

"permissible way to mitigate climate change impacts under CEQA." Plaintiffs do not

challenge that point. The issue is whether M-GHG-1 does so in a CEQA-compliant

manner, which the OPR document does not address.

(f) Forestry Protocol #3 (2013); (g) Revised Livestock Projects (2014); (h) U.S. Livestock version 4.0 (2017); (i) Organic Waste Digestion (2017); (j) Weatherization of Single Family and Multi-Family Buildings (2016); (k) Wetland Implementation and Rice Cultivation in the Sacramento-San Joaquin Delta, San Francisco Estuary and the Coast of California Version 1.0 (2016); Climate Action Reserve protocols: (a) Coal Mine Methane Version 1.1; (b) Forest Version 4.0 (2017); (c) Grassland Version 2.0 (2017); (d) Landfill Version 4.0 (2011); (e) U.S. Livestock Version 4.0; (f) Nitric Acid Production Version 2.1; (g) Nitrogen Management Version 1.1; (h) Organic Waste Composting Version 1.1; (i) Urban Forest Management Version 1.0 (2014); (j) Urban Tree Planting Version 2.0 (2014); (k) U.S. Ozone Depleting Substances Version 2.0; CARB protocols: (a) U.S. Forest Projects (2015); (b) Livestock Projects Capturing and Destroying Methane from Manure Management Systems (2014); (c) Mine Methane Capture Projects Capturing and Destroying Methane From U.S. Coal and Trona Mines (2014); (d) Ozone Depleting Substances Projects Destruction of U.S. Ozone Depleting Substances Banks (2014) ; (e) Urban Forest Projects (2011). 56 The County also contends that the Newhall Ranch Resource Management and

Development Plan (Newhall) is an "example of the type of project that helps the state

achieve its emission reduction goals." The County claims that the Newhall plan relies on

carbon offsets "from anywhere in the world for approximately 50 percent of its GHG

emission reductions . . . ." The County concludes, therefore, that statewide emissions

reductions "can be accomplished by reductions that occur out-of-state."

However, comparing M-GHG-1 to Newhall's GHG mitigation measures serves

only to demonstrate M-GHG-1's severe deficiencies. In Newhall, GHG mitigation

measures included requirements that (1) homes, commercial buildings, and public

facilities create as much energy as is used by implementing energy-efficient design and

renewable energy generation, such as solar panels; (2) every home (up to 21,500) be

equipped with an electric vehicle charging station; (3) 2,000 onsite charging stations be

installed in commercial and community areas; (4) subsidies for electric vehicle purchases

be provided; (4) electric school bus and neighborhood electric vehicle programs, transit

subsidies, tech-enabled mobility features, bike-share and car-share programs be provided;

and (5) energy efficient upgrades for schools and public buildings in disadvantaged

communities be constructed. M-GHG-1 contains none of these measures.

Moreover, Newhall's GHG mitigation identified "Direct Reduction Activities" that

"are prototypical" of GHG reduction measures the developer would implement. These

included (1) conservation of forest land to sequester GHG emissions; (2) funding clean

burning cook stoves for underprivileged households in foreign countries (more than three

billion people globally depend on burning wood fuels in archaic stone fires; a single clean

57 cook stove can save about two MTCO2e per year); and (3) programs for methane capture.

M-GHG-1 identifies no specific GHG offset protocols to be implemented.

Further, "to ensure environmental integrity," the Newhall GHG mitigation plan

required that any reduction or elimination be additional. It also defined additional using

both a legal requirement test and a performance test.30 As already explained, the text of

M-GHG-1 does not require additionality.

Moreover, the County is incorrect in claiming that Newhall's GHG mitigation plan

allowed carbon offsets "anywhere in the world for approximately 50 percent of its GHG

emission reductions." Actually, in Newhall at least 68 percent of project GHG emissions

reductions were required to be achieved in California. Moreover, at least 80 percent were

required to be achieved in the United States. In Newhall, even the possibility of 20

percent international offsets was reduced by requiring the developer to continue seeking

reasonable opportunities to obtain domestic offsets. M-GHG-1 has no similar limits on

international offsets.

And finally, in Newhall if the lead agency determines within 90 days that offsets

are noncompliant with performance standards, permitting ceases until that agency

30 The legal-requirement test requires that the activity "shall not be required for GHG reduction by applicable law (i.e., statute, ordinance or regulation) in effect at the time of the initiation" of the activity. The performance test requires that the activity "shall reduce GHG emissions below the applicable common industry practice for GHG reductions as in effect at the time" the activity is initiated. The performance test for a particular activity "shall be set in a protocol by an [a]pproved [r]egistry through analysis of standard practices and technology deployment in the applicable industry sector."

58 determines the standards have been met. Once again, M-GHG-1 has no safeguards for

after-acquired information invalidating a previously issued offset.

For the first time in its reply brief, the County also contends that M-GHG-1

reductions would be "additional" because the County "would not permit a project

applicant to mitigate . . . with out-of-County offsets until the applicant has exhausted the

project's onsite and in-County options. By not raising this in its opening brief, the

County has forfeited the point. (Doe v. California Dept. of Justice (2009) 173

Cal.App.4th 1095, 1115 (Doe) [" ' "Obvious considerations of fairness in argument

demand that the appellant present all of his points in the opening brief. To withhold a

point until the closing brief would deprive the respondent of his opportunity to answer it

or require the effort and delay of an additional brief by permission." ' "].) Moreover,

even if we were to consider this argument, it fails because it is based on a fundamental

misunderstanding. Additionality is not a geographic limitation, but rather considers

whether the offset would have otherwise occurred.

Again for the first time in its reply, citing Our Children's, supra, 234 Cal.App.4th

at page 882, the County contends that GHG emission reductions under M-GHG-1 are

additional because they "would be additional to other legislatively-mandated reductions

as assured by compliance with [s]ection 38562." This point is also forfeited. (Doe,

supra, 173 Cal.App.4th at p. 1115.) Moreover, as explained ante, M-GHG-1 does not

invoke subdivision (d)(2) of section 38562. The offset program analyzed in Our

Children's does. (Our Children's, at p. 877.)

59 E. M-GHG-1 Violates CEQA By Improperly Deferring Mitigation

Under M-GHG-1, the Director determines whether to approve offset credits. That

decision is based on two determinations. First, the registry or issuing entity must be

CARB-approved or "reputable" and issue offsets consistent with section 38562,

subdivision (d)(1). Second, the offsets must not be "available" and/or not "financially

feasible" in a location closer to the County as listed in the geographical hierarchy.

Plaintiffs contend that M-GHG-1 violates CEQA by improperly delegating and deferring

mitigation to these future determinations. We agree.

"Formulation of mitigation measures shall not be deferred until some future time."

(Guidelines, § 15126.4, subd. (a)(1)(B).) However, the specific details of a mitigation

measure . . . may be developed after project approval when it is impractical or infeasible

to include those details during the project's environmental review provided that the

agency (1) commits itself to the mitigation, (2) adopts specific performance standards the

mitigation will achieve, and (3) identifies the type(s) of potential action(s) that can

feasibly achieve that performance standard and that will considered, analyzed, and

potentially incorporated in the mitigation measure." (Ibid.; see also Forest Foundation,

supra, 17 Cal.App.5th at pp. 442-443.) Where an EIR improperly defers mitigation, the

approving agency abuses its discretion by failing to proceed as required by law. (CBE,

supra, 184 Cal.App.4th at pp. 89-90.)

Citing Oakland Heritage Alliance v. City of Oakland (2011) 195 Cal.App.4th 884

(Oakland Heritage), the County contends that M-GHG-1 is "similar to mitigation

measures upheld by courts that require plans or purchasing of offsets subject to review

60 and approval by an agency official." In Oakland Heritage, the appellate court upheld a

mitigation measure deferring site-specific earthquake mitigation measures. However, the

EIR in Oakland Heritage required the developer to submit a design level investigation for

each parcel that would "be in accordance with applicable City ordinances and policies

and consistent with the most recent version of the California Building Code, which

requires structural design that can accommodate ground accelerations expected from

known active faults." (Id. at p. 889.) The EIR also required that the design level

investigation would be reviewed by a structural engineer, a registered geotechnical

engineer, and submitted to "the City Building Services Division . . . 'to ensure compliance

with the applicable requirements of the geotechnical investigation as well as other

applicable code requirements.' " (Id. at p. 894.) The EIR further contained "an extensive

discussion of the mandates of various state and [c]ity laws bearing upon seismic safety,

including the Seismic Hazards Mapping Act [citation], the Building Code . . ., and

various City ordinances." (Id. at p. 892.) The EIR concluded that " '[c]onsidering the

rigorous investigation process required under the engineering standard of care,

compliance with state laws and local ordinances, and regulatory agency technical

reviews, the mitigation measures . . . will reduce the risk of seismic hazards and ensure

that impacts associated with development [of the] . . . Project area would remain less than

significant.' " (Id. at p. 910.)

Oakland Heritage concluded that the EIR sufficiently addressed potential

environmental impacts associated with seismicity. The court noted that the EIR

"discussed the statutes and regulations aimed at increasing seismic safety." (Oakland

61 Heritage, supra, 195 Cal.App.4th at p. 907.) The EIR also "discussed the responsibilities

of the engineers and building officials and the processes to ensure that site investigations,

grading, and construction are completed in accordance with the laws designed to protect

the public and property from the effects of earthquake shaking and ground failure." (Id.

at pp. 908-909.)

Contrary to the County's assertions, the mitigation measure in Oakland Heritage

is materially distinguishable from M-GHG-1. In Oakland Heritage, the delegation to

staff was based on objective statutory standards. In contrast here, M-GHG-1 provides

only a generalized goal of no increase or net zero GHG emissions, and then allows the

Director to determine whether any particular offset program is acceptable based on

unidentified and subjective criteria.

Deferred mitigation violates CEQA if it lacks performance standards to ensure the

mitigation goal will be achieved. For example, in CBE, supra, 184 Cal.App.4th 70, the

appellate court struck down deferred mitigation for GHG emissions reduction because the

mitigation measure "merely propose[d] a generalized goal of no net increase in

greenhouse gas emissions and then set[] out a handful of cursorily described mitigation

measures for future consideration that might serve to mitigate the 898,000 metric tons of

emissions resulting from the Project." (Id. at p. 93.) The mitigation measures were

undefined, and "[t]he only criteria for 'success' of the ultimate mitigation plan" was "the

subjective judgment of the City Council, which presumably will make its decision

outside of any public process a year after the Project has been approved." (Ibid.) The

mitigation plan in CBE violated CEQA because it "offered no assurance that the plan for

62 how the [p]roject's greenhouse gas emissions would be mitigated to a net-zero standard

was both feasible and efficacious . . . ." (Id. at p. 95.)

M-GHG-1 violates CEQA in much the same ways as did the deferred mitigation

plan addressed in CBE. As there, M-GHG-1 sets a generalized goal—no net increase or

net-zero GHG emissions. And also like CBE, achieving that goal depends on

implementing unspecified and undefined offset protocols, occurring in unspecified

locations (including foreign countries), the specifics of which are deferred to those

meeting one person's subjective satisfaction.

Endangered Habitats League, Inc. v. County of Orange (2005) 131 Cal.App.4th

777 (Endangered Habitats) is another instructive example of improper deferred

mitigation. There, the EIR required an acoustical report to demonstrate structures were

designed to meet noise standards "satisfactory to the manager of the county's building

permit division." (Id. at pp. 793-794.) The Court of Appeal held this violated CEQA

because it "does no more than . . . allow approval by a county department without setting

any standards." (Id. at p. 794.)

Like the improper deferred mitigation plans in CBE and Endangered Habitats, M-

GHG-1 contains no objective standards for determining whether any particular offset

project is "available" and "financially feasible" in one location or another. Without any

objective and measurable standard for what "feasible" onsite reductions consist of,

M-GHG-1 provides no reasonable assurance that any onsite GHG reduction will actually

occur.

63 This concern is not merely theoretical. The County has approved GPAs using

GHG mitigation measures similar to M-GHG-1 that will use a staggering amount of

offsite carbon credits. For example, the County-approved Newland Sierra project

planned to mitigate 82 percent of its GHG emissions with offsite offsets.31

Especially troubling is that M-GHG-1 contains no objective standards for the

Director to apply in determining whether offsets originating in foreign countries are real,

permanent, verifiable, enforceable, and additional. As one commentator notes, the

ordinary challenges in establishing that a domestic offset protocol meets these standards

are magnified in foreign countries:

"The main motivation in encouraging offsets in developing countries is the enhancement of forests. The question becomes, what is the business-as-usual scenario in a situation when deforestation, the destruction of forests, is business as usual? If a lowering of the rate of deforestation is considered an emissions reduction, all that means is less trees are being cut down. This is a far cry from the [C]ARB's domestic Urban Forest Protocol using a performance standard of a net gain in trees. Until there is actually an increase in trees, the ability to remove carbon continues to decline and yet offsets can be rewarded." (Ramo Offset, supra, 20 Hastings W.-Nw. J Envt'l L. & Pol'y at p. 149.)

The administrative record in this case echoes some of these same concerns,

stating, "The complexity of the offset program . . . is certain to result in some inaccuracy,

and potentially in fraud. These uncertainties are one of the reasons that CARB limits the

use of offsets in the Cap-and-Trade program to no more than 8 [percent] of the total."

31 In March 2020, a majority of the electorate voted to repeal the Board of Supervisors' amendment of the General Plan associated with the Newland Sierra project.

64 However, under M-GHG-1, the Director's findings of unavailability and feasibility could

allow a GPA applicant to offset all project GHG emissions through credits originating in

foreign countries.

M-GHG-1 also entrusts to the "satisfaction of the Director" whether the proposed

offset registry is "reputable" and the protocol being implemented by the registry is

"consistent" with section 38562, subdivision (d)(1)—that is, whether the projected GHG

reductions are "real, permanent, verifiable and enforceable." However, M-GHG-1 has no

objective criteria for making such findings.32 In contrast, to ensure that GHG reductions

are real, CARB requires the reduction be "a direct reduction within a confined project

boundary." Thus, "[r]ecycling activities would not be eligible for offset credit as the

recycling activities do not have a direct GHG reduction at the recycling facility. . . ."

M-GHG-1 contains no similar standards. To ensure permanency, CARB requires there

be "no opportunity for a reversal of the avoided emissions." This is implemented, for

example, in CARB's forestry protocol, which requires sequestering carbon "for at least

100 years." But M-GHG-1 lacks any permanency criteria. To ensure emissions

reductions are additional, CARB will not approve a protocol "for a project type that

32 At oral argument, the County asserted that objective criteria guides the Director's discretion under M-GHG-1 because there must be "sufficient credits"—i.e., an amount of carbon offsets to result in a GPA project having zero GHG emissions above the CAP. It is undoubtedly true that determining the amount of GHG reductions needed to obtain net zero is objective because it is a mathematical calculation. However, this begs the question whether the calculated GHG emissions reduction will actually be obtained. That is determined by the validity of the protocol being implemented, and M-GHG-1 does not require Assem. Bill No. 32 compliant protocols.

65 includes technology or GHG abatement practices that are already widely used."

However, M-GHG-1 contains no such objective criteria.

It is true that M-GHG-1 establishes a goal of no net increase above the CAP's

GHG emission projections. However, courts have invalidated deferred mitigation

measures having similar generalized goals that lack performance standards. (CBE, supra,

184 Cal.App.4th at p. 93 [no "net increase" in GHG emissions]; Gray v. County of

Madera (2008) 167 Cal.App.4th 1099, 1118-1119 (Gray) [mitigation measure aimed at

restoring water supplies governed only by generalized goal, not specific performance

criteria]; San Joaquin Raptor Rescue Center v. County of Merced (2007) 149 Cal.App.4th

645, 670 [measures intended to protect vernal pools relied on generalized goal and lacked

specific performance criteria or standards].)

In defending M-GHG-1, the County asserts that CEQA permits shifting the

responsibility to perform a mitigation measure to agency staff's discretion. The County

contends the discretion given the Director under M-GHG-1 is similar to mitigation

upheld in California Clean Energy Committee v. City of Woodland (2014) 225

Cal.App.4th 173 (California Clean), Mount Shasta Bioregional Ecology Center v. County

of Siskiyou (2012) 210 Cal.App.4th 184 (Mount Shasta), and Gray, supra, 167

Cal.App.4th 1099. However, these cases do not support the County's claims.

In California Clean, a city certified an EIR for a 234-acre shopping center. A

mitigation measure required the developer to submit a market study and urban decay

analysis for approval by the city's community development department (Department).

(California Clean, supra, 225 Cal.App.4th at p. 193.) The appellate court held that the

66 mitigation measure properly delegated review and approval authority to the Department.

However, the court held the measure violated CEQA by failing to specify actions

required to alleviate urban decay. (Id. at pp. 193-195.) Similarly here, there is nothing

inherently unlawful under CEQA by delegating M-GHG-1 determinations to the

Director. The problem is that M-GHG-1 contains no objective criteria for exercising that

discretion to ensure that the GHG emissions reduction goals are actually met.

In Mount Shasta, plaintiffs challenged an EIR for a project expanding an existing

manufacturing facility. (Mount Shasta, supra, 210 Cal.App.4th at p. 190.) The Court of

Appeal upheld noise mitigation measures that required postoperation acoustical testing if

noise exceeded the level of significance (an increase of at least 3.0 dBA and an overall

noise level above the applicable city or County standard). (Id. at p. 208.) However,

unlike Mount Shasta, here M-GHG-1 contains no objective standard to govern the

Director's discretion. Feasible means "capable of being accomplished in a successful

manner within a reasonable period of time, taking into account economic, environmental,

legal, social, and technological factors." (Guidelines, § 15364.) M-GHG-1 contains no

objective criteria for the Director to apply in making these factual determinations.

M-GHG-1's lack of objective standards is well illustrated by comparing it to the

mitigation measure in Sierra Club, supra, 6 Cal.5th 502. That case involved an EIR for a

planned community of 2,500 homes. (Id. at p. 508.) A mitigation measure provided that

HVAC units would be equipped with a catalyst if "reasonably available and economically

feasible." (Id. at p. 525.) The Supreme Court held that mitigation measure passed CEQA

muster because the EIR objectively defined "economically feasible" to mean costing less

67 than 10 percent of the base HVAC cost. (Ibid.) In contrast here, M-GHG-1 contains no

objective standard of feasibility.

The County's reliance on Gray, supra, 167 Cal.App.4th 1099 is also untenable.

There, to mitigate night light impacts, the EIR required that exterior lighting shall be

designed and maintained "such that glare and reflections are contained within the

boundaries of the parcel, and shall be hooded and directed downward and away from

adjoining properties and public rights-of-way." (Id. at p. 1126.) The measure also

prohibited blinking and flashing lights and provided that all light fixtures "shall be

appropriate to the use they are serving in scale, intensity, and height." (Ibid.) The

measure stated, "[A]ll exterior lighting will be designed, installed and operated as

required by the Planning Director." (Ibid.) The Court of Appeal upheld the measure

because the agency had committed itself to "specific performance standards"—that

lighting be hooded and directed away from adjacent properties and towards the project

site. (Id. at p. 1127.) M-GHG-1 is materially different because mitigation measures are

based on the Director's private and subjective discretionary determinations.

In a related argument, citing Sacramentans for Fair Planning v. City of

Sacramento (2019) 37 Cal.App.5th 698 (Sacramentans), the County also asserts that the

Director's discretion under M-GHG-1 is "no greater" than the discretion afforded to the

staff member in that case to determine that a housing project provided "a significant

community benefit." However, the discretionary issue in Sacramentans was whether the

68 city's approval resulted from an unconstitutional delegation of legislative authority. (Id.

at p. 716.) The case does not involve deferred mitigation.33

The County also defends M-GHG-1's lack of objective standards by emphasizing

that scientific knowledge in this area is constantly evolving. We agree that an agency

should be encouraged to adopt flexible mitigation measures that can adapt as better

technology becomes available (unless those changes increase the project's significant

impacts). (See Sierra Club, supra, 6 Cal.5th at p. 524.) However, "the novelty of

greenhouse gas mitigation measures is one of the most important reasons 'that mitigation

measures timely be set forth, that environmental information be complete and relevant,

and that environmental decisions be made in an accountable arena." (CBE, supra, 184

Cal.App.4th at p. 96.) Although "foreseeing the unforeseeable is not possible, an agency

must use its best efforts to find out and disclose all that it reasonably can." (Ibid.)

The County's reliance on California Native Plant Society v. City of Rancho

Cordova (2009) 172 Cal.App.4th 603 (Native Plant) is also unpersuasive. There, a

project significantly impacted vernal pool habitat. (Id. at p. 610.) Mitigation measures

included acquiring offsite habitat. (Id. at p. 612.) Project opponents asserted that the

agency improperly deferred mitigation by failing to specify where offsite vernal pools

might be acquired. (Ibid.) The Court of Appeal rejected that contention because the

33 The CEQA issues in Sacramentans were whether (1) the regional transportation and emissions reduction plan were inadequate; and (2) the impact analysis improperly tiered to prior environmental impact reports. (Sacramentans, supra, 37 Cal.App.5th at p. 718.) 69 mitigation measure included objective criteria—replacement habitat in a specified ratio

(2:1) to the habitat lost from the project. (Id. at pp. 621-622.) The case is inapposite

because M-GHG-1 lacks objective criteria to ensure mitigation is effective.

Citing Gentry v. City of Murrieta (1995) 36 Cal.App.4th 1359, the County also

contends that "courts have upheld mitigation measures such as M-GHG-1 where a

building official . . . must review and approve a plan or proposed implementation of a

mitigation measure, essentially performing a mitigation monitoring function." However,

this argument misses the target. The CEQA defect in M-GHG-1 is not that it allows one

person—the Director—to make discretionary decisions. The problem is M-GHG-1 lacks

objective criteria to ensure the Director's exercise of that discretion will result in GHG

reduction that is real, permanent, quantifiable, verifiable, enforceable, and additional.

Unlike M-GHG-1, the mitigation measure in Gentry was "subject to a host of specific

performance criteria imposed by various ordinances, codes, and standards, as well as

other mitigation conditions." (Id. at p. 1395.)

F. The Effect of M-GHG-1's Invalidity on the CAP

After determining that M-GHG-1 was invalid under CEQA, the superior court also

held the CAP was invalid because it "expressly incorporated" M-GHG-1 by reference.

As explained ante, we read the CAP differently because M-GHG-1 is not a CAP GHG

emission reduction measure for GPU-consistent projects, but rather is a mitigation

measure for GPAs in the SEIR. Nevertheless, we too conclude that the CAP is tainted by

M-GHG-1, albeit on somewhat different grounds.

70 The CAP contains in-County GHG projections for 2020, 2030, and 2050. Those

projections perform important CEQA functions by (1) informing the public of the total

GHG emissions to be expected if the CAP is implemented; and (2) determining the extent

to which a GPU-consistent project must eliminate or reduce GHG emissions to be within

the threshold of significance.

These projections exclude forecasted GHG emissions from future GPAs and

in-process GPAs that the County had not adopted by August 2017. The CAP excludes

these on the assumption that in-process and future GPAs will mitigate GHG emissions

above the CAP to zero under M-GHG-1. Because M-GHG-1 is invalid, there is no

factual basis for that assumption. Accordingly, to this extent the CAP's finding that

in-process and future GPAs would not result in significant GHG impacts is not supported

by substantial evidence.

G. The SEIR Discloses M-GHG-1's 30-Year Shelf Life

Golden Door contends that the CAP and SEIR are misleading because they do not

disclose that M-GHG-1 requires offsets for only 30 years, after which "any purported

GHG reductions from offset credits vanish, and the County's ability to meet GHG targets

worsens significantly." However, the SEIR states, "M-GHG-1 . . . requires GPAs that

increase density or intensity above the 2011 GPU to offset additional (Option 1) or all

(Option 2) GHG emissions for a 30-year period." The SEIR also explains that a 30-year

71 project life is "consistent with the 30-year project lifetime frame used by the South Coast

Air Quality Management District's GHG guidance (SCAQMD 2008)."

III.

CUMULATIVE IMPACTS

A. Additional Background

The SEIR identifies 21 GPAs. These include Newland Sierra (2,135 dwelling

units), Otay 250 (up to 3,158 dwelling units), and Otay Ranch Village 14 (1,119 dwelling

units).34

The SEIR acknowledges that these in-process GPAs "are reasonably foreseeable

[and] have sufficient detail and plans to understand the changes in land use conditions

that are proposed . . . ." The SEIR also acknowledges that these GPAs are "probable

future projects that when combined with the [P]roject, could result in a cumulatively

considerable effect." The SEIR addresses cumulative GHG impacts from these GPAs by

requiring them to mitigate under M-GHG-1. The issue here is whether CEQA requires

analysis of cumulative impacts from in-process GPAs other than, and in addition to, their

projected GHG emissions.

Although conceding that "[t]he SEIR properly finds that GPAs are reasonably

foreseeable," the County claims no additional cumulative impacts analysis is required

because (1) "the parameters of those projects remained highly speculative"; and (2) the

34 Sierra Club's request for judicial notice of the County's plans for review and approval of the Otay Ranch Village 14 GPA, and that project's draft EIR is denied as irrelevant. (SDOG, supra, 13 Cal.App.5th at p. 90, fn. 8.)

72 County did not know whether the in-process GPAs would rely on carbon offsets, "and if

so, whether that reliance would . . . result in other impacts such as air quality, noise,

energy, or transportation . . . ." For the first time in its reply brief, the County further

contends that even if in-process GPAs would "vastly increase GHG emissions, energy

impacts, and air emissions through unaccounted VMT increases," there is no harm

because "[t]he CAP would reduce GHG emissions and related air quality and energy

impacts compared to conditions without the CAP."35

B. Cumulative Impacts and the Standard of Review

A cumulative impact is one "created as a result of the combination of the project

evaluated in the EIR together with other projects causing related impacts". (Guidelines,

§ 15130, subd. (a)(1).) "The cumulative impact from several projects is the change in the

environment which results from the incremental impact of the project when added to

other closely related past, present, and reasonably foreseeable probable future projects."

(Id., § 15355, subd. (b).)

Environmental impacts of probable future projects must be analyzed because

"consideration of the effects of a project or projects as if no others existed would

encourage the piecemeal approval of several projects that, taken together, could

35 Also for the first time in its reply brief, the County claims that the SEIR analyzed air quality emissions from "reasonably foreseeable" GPAs "based on their location and proposed mix of uses . . . ." However, by not raising these arguments in its opening brief, the County has forfeited them. (Doe, supra, 173 Cal.App.4th at p. 1115.) Applying forfeiture is especially appropriate because in the opening brief, the County took a contrary position, asserting that no cumulative impact analysis beyond GHG emissions was required.

73 overwhelm the natural environment and disastrously overburden the man-made

infrastructure and vital community services. This would effectively defeat CEQA's

mandate to review the actual effect of the projects upon the environment." (Las Virgenes

Homeowners Fed'n v. County of L. A. (1986) 177 Cal.App.3d 300, 306.) The agency

must interpret this requirement to " 'afford the fullest possible protection of the

environment.' " (Friends of the Eel River v. Sonoma County Water Agency (2003) 108

Cal.App.4th 859, 868 (Eel River).)

An EIR must analyze cumulative impacts of a project when the project's

incremental effect is cumulatively considerable. (Guidelines, § 15130, subd. (a);

Bakersfield Citizens for Local Control v. City of Bakersfield (2004) 124 Cal.App.4th

1184, 1214 (Bakersfield Citizens).) Moreover, if a mitigation measure would itself create

new significant environmental impacts, these too must be discussed, "though in less

detail than required for those caused by the project itself." (Forest Foundation, supra,

17 Cal.App.5th at p. 432.)

Even where, as here, a program EIR is involved, "[t]he fact more precise

information may be available during the next tier of environmental review does not

excuse [the agency] from providing what information it reasonably can now. [Citation.]

Moreover, if known impacts are not analyzed and addressed in a program EIR, they may

potentially escape analysis in a later-tier EIR." (Forest Foundation, supra, 17

Cal.App.5th at p. 440.) "If, on the other hand, the cumulative impact is insignificant or if

the project's incremental contribution to the impact is not cumulatively considerable, the

lead agency is not required to conduct a full cumulative impacts analysis, but the EIR

74 must include a brief explanation of the basis for the agency's finding(s)." (San Francisco

Baykeeper, Inc. v. State Lands Com. (2015) 242 Cal.App.4th 202, 222 (SF Baykeeper).)

" 'We review an agency's decision regarding the inclusion of information in the

cumulative impacts analysis under an abuse of discretion standard. "The primary

determination is whether it was reasonable and practical to include the projects and

whether, without their inclusion, the severity and significance of the cumulative impacts

were reflected adequately." ' " (Rodeo Citizens Assn. v. County of Contra Costa (2018)

22 Cal.App.5th 214, 231 (Rodeo Citizens).)

C. The SEIR's Cumulative Impacts Analysis Fails Because It Does Not Address Impacts by GPAs Mitigating GHG Emissions under M-GHG-1

When conducting a cumulative impacts analysis, an agency must include closely

related projects that are currently under environmental review. This is because once

review is begun, a significant investment of time, money, and planning has probably

occurred. Thus, once an EIR is initiated, the project is probable rather than merely

possible. (Eel River, supra, 108 Cal.App.4th at p. 870.)

For example, in San Franciscans for Reasonable Growth v. City & County of San

Francisco (1984) 151 Cal.App.3d 61 (SFRG), the agency considered a proposal to

construct high-rise downtown office buildings. (Id. at p. 67.) As part of its cumulative

impacts analysis, the agency considered the amount of new office space that would be

added to the area by other approved projects. (Id. at p. 68.) Project opponents asserted

that the agency violated CEQA by failing to consider projects then under environmental

review. (Id. p. 74.) The Court of Appeal agreed, stating, "Because projects under

75 environmental review . . . could easily have been ascertained by the [agency] from its

own records, there was no practical or reasonable barrier to their disclosure and inclusion

in the analyses. . . . The only reason we can infer for the [agency's] failure to consider

and analyze this group of projects was that it was more expedient to ignore them." (Ibid.)

Elaborating, the appellate court stated:

"First, experience and common sense indicate that projects which are under review are ['reasonably] foreseeable probable future projects. . . .' Ordinarily an office building project that is awaiting environmental approval has reached a stage of development where the developer, financial institutions, and contractors almost certainly view its construction to be a very real probability, and not without reason. Such a view is doubtless shared by those performing the environmental review and preparing the EIR.

"Second, we find it illogical that an EIR should carefully evaluate the direct impacts of one project which is 'under environmental review,' but completely ignore the cumulative impacts of that project's siblings in the same category. Nothing makes the EIR's subject project more 'probable' or 'foreseeable' than any of the other projects under review, just as nothing makes them less so." (SFRG, supra, 151 Cal.App.3d at p. 75.)

Here, the 21 in-process GPAs, if constructed, would collectively add nearly

14,000 dwelling units in the unincorporated County. The EIRs for just five of these

disclose they will collectively produce 139,485 MTCO2e in construction-related GHG

emissions alone.36 However, the SEIR does not analyze these cumulative impacts—

except by stating that in-process GPAs will mitigate to zero above the CAP under

M-GHG-1.

36 One hundred thirty nine thousand four hundred eighty five MTCO2e is equivalent to about one year of GHG emissions from 30,000 combustion engine cars.

76 These in-process GPAs are closely related projects currently under environmental

review. They are closely related because the CAP and SEIR address GHG emissions

reduction in the unincorporated County and from County operations, and the GPAs will

create GHG emissions in this same geographic area. These GPAs are in the process of

environmental review by the County as lead agency. Accordingly, the SEIR should have

considered whether these GPAs (listed in Table 1-3 of the SEIR) would create

cumulatively considerable impacts in addition to GHG impacts in combination with the

Project.37 As Golden Door correctly notes, cumulative impacts from adding 14,000

dwellings and related infrastructure in projects utilizing M-GHG-1 (and, therefore, using

offsite carbon offsets to mitigate their in-County GHG emissions) would likely include

impacts to air quality, energy, and vehicle miles traveled, among others. "The absence of

this analysis makes the [S]EIR an inadequate informational document." (Eel River,

supra, 108 Cal.App.4th at p. 872.)

The County contends that analyzing cumulative impacts (in addition to GHG

impacts) from in-process GPAs requires an inappropriate level of detail for the SEIR.

However, the detail required for a cumulative impact analysis is based on reasonableness

and practicality. (Rodeo Citizens, supra, 22 Cal.App.5th at p. 231.) In this case, the

SEIR admits that the in-process GPAs are "reasonably foreseeable [and] have sufficient

detail and plans to understand the changes in land use conditions that are proposed."

37 SEIR Table 1-3 contains "the complete list of GPAs" that were under County review as of August 2017.

77 Despite knowing that (1) these probable GPAs would add some 14,000 homes, and

(2) these projects would implement M-GHG-1 by using offsite carbon offsets—the

County did not analyze any of their cumulative impacts apart from GHG emissions

(which the SEIR concluded would be mitigated to zero above the CAP.) The problem

here is not a lack of detail about a cumulative impact considered; the CEQA defect is the

failure to analyze any such cumulative impact at all.

The County does not explain how the GPAs could be probable and foreseeable

enough to create cumulatively considerable GHG impacts, but not probable and

foreseeable enough to create, for example, vehicle miles traveled impacts from projects

expected to add 14,000 new homes to the backcountry. Of course, if a potential

cumulative impact is insignificant, the lead agency is not required to conduct "a full

cumulative impacts analysis," but must explain the basis for the finding of insignificance.

(SF Baykeeper, supra, 242 Cal.App.4th at p. 222.) However, the SEIR also fails to

engage in that analysis.

The County also defends its failure to analyze these cumulative impacts by

asserting, "CEQA does not require the SEIR to speculate about whether the County

would approve pending project applications or the conditions imposed should the County

approve them." Citing Sacramento Old City Assn. v. City Council (1991) 229

Cal.App.3d 1011 (Sacramento Old City) and Environmental Council of Sacramento v.

City of Sacramento (2006) 142 Cal.App.4th 1018 (Environmental Council of

Sacramento), the County asserts that "[e]ven though applications for GPAs

existed . . . the parameters of those projects remained highly speculative." The County

78 claims it did not know of changes that might be made "during the public process, whether

the future and proposed projects would rely on carbon offsets, and if so, whether that

reliance would . . . result in other impacts such as air quality, noise, energy, or

transportation." The County repeated this at oral argument, noting that after the County

certified the SEIR, the general plan amendment for one of the in-process GPAs was set

aside by referendum.

However, the SEIR itself contradicts the claim that the GPAs were too speculative.

Table 1-3 of the SEIR contains a list of "past, present, and probable future projects that

when combined with the [P]roject could result in a cumulatively considerable effect."

(Italics added.) Moreover, the County's reliance on Sacramento Old City and

Environmental Council of Sacramento for the opposite conclusion is unavailing. In both

cases, the future projects were not then in any stage of development. In Sacramento Old

City, plaintiffs challenged an EIR for a project expanding a convention center and

constructing an office tower. (Sacramento Old City, supra, 229 Cal.App.3d at p. 1016.)

Among other things, the EIR determined that an additional 2,621 parking spaces would

be needed. (Id. at p. 1020.) Plaintiffs argued that mitigation measures to accommodate

the 2,600 parking space deficit would include constructing new downtown parking lots,

erecting a large parking garage, or shuttling hundreds of people from outlying parking

areas—all of which in themselves would create substantial cumulative environmental

impacts that must be analyzed in the EIR, but were not. (Id. at p. 1030.) The Court of

Appeal rejected that contention, stating, " 'prophecy' is not required in an EIR" and "[n]or

79 do we require discussion in the EIR of specific future action that is merely contemplated

or a gleam in the planner's eye." (Id. at p. 1031.)

Environmental Council involved a habitat conservation plan and implementation

agreement for protecting hawks and snakes in a 53,537 acre basin. (Environmental

Council of Sacramento, supra, 142 Cal.App.4th at p. 1023.) The conservation plan

established a program to minimize and mitigate the expected loss of habitat and

incidental killing of covered species that could result from authorized urban development

of 17,500 acres. (Id. at p. 1025.) Subsequently, the city and county adopted a

memorandum of understanding (MOU) outlining an approach for future agreements

regarding land use in the basin. (Id. at pp. 1029-1030.) The MOU did not approve

development nor involve any specific development proposals. (Id. at p. 1030.) No funds

were committed under the MOU, and the MOU did not change any existing land use

requirements but rather contemplated further discretionary approvals and environmental

review. (Ibid.) A federal court described the MOU as "tentative" and stated that

development under the MOU "was not reasonably certain to occur . . . ." (Ibid.) The

plaintiffs in Environmental Council asserted that CEQA required the agencies to consider

cumulative impacts from the MOU. (Id. at pp. 1028-1029.) The Court of Appeal

rejected that argument because the MOU involved "unspecified and uncertain

development that might be approved in the future" and "[f]ar too little is known about the

scope, the location, or the types of projects that might be proposed in the future . . . ."

(Id. at p. 1032.)

80 In sharp contrast here, the in-process GPAs were well beyond the initial planning

stages. The County knew the scope, location, types of projects being proposed and, in

some cases, even specific amounts of GHG emissions that would be mitigated with offset

credits originating out of County. In the superior court, the County filed a declaration by

one of its planning managers, who authenticated excerpts from the Lake Jennings

Marketplace EIR. That EIR requires the applicant to purchase 2,708 MTCO2e in offset

credits before the first grading permit is issued and another 71,880 MTCO2e of credits

before the first certificate of occupancy is issued. In the same declaration, the planning

manager also authenticated EIR excerpts of five other in-process GPAs with similar GHG

mitigation measures. As summarized in the table post, these in-process GPAs will

mitigate GHG emissions by purchasing listed amounts of offset credits, almost certainly

originating outside the County:

Project EIR date Offset Provision Summary Newland Sierra38 Draft EIR circulated Requires carbon offsets for June 2017. approximately 82 percent of its GHG emissions. Allows international offsets. Warner Ranch Draft EIR circulated Requires purchasing 2,413 MTCO2e December 2016. in annual carbon offsets. Harmony Grove Draft EIR in April Requires 4,411 MTCO2e in offset Village South 2017, revised in credits before issuance of the first February 2018. grading permit and thereafter 5,222 annually; allows international offsets.

38 The administrative record contains public communications stating that the Newland Sierra project includes a GPA that would add over 2,100 homes in an area zoned for only 99 homes in the GPU and is six miles from the nearest public transit center.

81 Valiano Final EIR published in Requires offset credits up to 6,123 February 2018. MTCO2e to mitigate construction- related GHG emissions and 4,493 annually for operational GHG emissions. Otay 250 Final EIR published in Even with onsite mitigation, the March 2018. project will result in 37,554 MTCO2e that may be mitigated with offsets, including internationally.

As lead agency, the County had access to these EIRs and, therefore, was not

required to speculate about their contents. The County knew or reasonably should have

known that these GPAs would almost certainly be purchasing out-of-County credits to

offset in-County GHG emissions. Accordingly, the SEIR was required to consider

whether these GPAs and others like them would lead to significant cumulative impacts in

combination with the Project.

In a related argument, the County urges that cumulative impact analysis should be

deferred until project-specific environmental review of each of the GPAs. However, in

Forest Foundation, this court rejected a similar argument, stating: " 'Designating an EIR

as a program EIR . . . does not by itself decrease the level of analysis otherwise required

in the EIR. [I]n considering a challenge to a program EIR, 'it is unconstructive to ask

whether the EIR provided "project-level" as opposed to "program-level" detail and

analysis. Instead, we focus on whether the EIR provided "decisionmakers with sufficient

analysis to intelligently consider the environmental consequences of [the] project.' "

(Forest Foundation, supra, 17 Cal.App.5th at p. 426.)

82 In sum, the SEIR's cumulative impact analysis is inadequate because it fails to

address reasonably known cumulatively considerable impacts from probable GPAs

utilizing M-GHG-1 to mitigate GHG emissions by purchasing out-of-County offsets.39

IV.

THE SEIR'S FINDING OF CONSISTENCY WITH THE REGIONAL TRANSPORTATION

PLAN IS NOT SUPPORTED BY SUBSTANTIAL EVIDENCE

A. Senate Bill No. 375—Background

In 2008, the Legislature enacted the Sustainable Communities and Climate

Protection Act (Stats. 2008, ch. 728, § 1; Stats. 2009, ch. 354, § 5), commonly known as

Senate Bill No. 375 (Sen. Bill No. 375), to reduce GHG emissions through improved land

use and transportation planning. Sen. Bill No. 375's findings and legislative declarations,

quoted in part below, emphasize the necessity for changed land use patterns and

improved transportation to meet Assem. Bill No. 32 goals:

"(a) The transportation sector contributes over 40 percent of the greenhouse gas emissions in the State of California; automobiles and light trucks alone contribute almost 30 percent. The transportation sector is the single largest contributor of greenhouse gases of any sector. [¶] . . . [¶]

"(c) Greenhouse gas emissions from automobiles and light trucks can be substantially reduced by new vehicle technology and by the increased use of low carbon fuel. However, even taking these measures into account, it will be necessary to achieve significant additional greenhouse gas reductions from changed land use patterns and improved transportation. Without improved land use and transportation policy, California will not be able to achieve the

39 Our analysis assumes without deciding that the GHG mitigation measure(s) in EIRs for these in-process GPAs is/are lawful. Those projects are not before us and we express no opinion on that issue. Under Sen. Bill No. 375, CARB must develop region-by-region emission

reduction targets for automobiles and light trucks for 2020 and 2035. (Gov. Code,

§ 65080, subd. (b)(2)(A).) "The targets set by CARB for the San Diego region, using a

2005 baseline, require a 7 percent per capita reduction in greenhouse gas emissions by

2020 and a 13 percent per capita reduction by 2035." (Cleveland National, supra, 3

Cal.5th at p. 506.)

Metropolitan planning organizations (MPOs) are also involved in implementing

Sen. Bill No. 375. MPOs are federally required organizations comprised of

representatives of local government, transportation agencies, and state officials.

(23 U.S.C. § 134.) The San Diego Association of Governments (SANDAG) is the MPO

for the San Diego region.

Under Sen. Bill No. 375, each MPO must draft and adopt a Sustainable

Communities Strategy (SCS) as part of its regional transportation plan (RTP). (Gov.

Code, § 65080, subd. (b)(2)(B).) CARB reviews and either approves or rejects each SCS.

(Id., subd. (b)(2)(J)(ii).)

An SCS establishes how planned land uses and transportation projects will achieve

CARB's GHG reduction targets. These include "a forecasted development pattern for the

region, which, when integrated with the transportation network, and other transportation

measures and policies, will reduce the greenhouse gas emissions from automobiles and

light trucks to achieve, if there is a feasible way to do so, the greenhouse gas emission

84 reduction targets approved by [CARB] . . . ." (Gov. Code, § 65080, subd. (b)(2)(B)(vii).)

An SCS must also (1) assess how to provide housing for all income levels of the regional

population, projected eight years into the future; and (2) identify a transportation network

to service the region's transportation needs. (Id., subd. (b)(2)(B)(iii) & (iv).)

"The reductions mandated by [Sen. Bill No. 375] may be achieved through a

variety of means, including 'smart growth' planning to maximize building densities at

locations served by public transit and to locate residences near needed services and

shopping to reduce automobile dependency.[40] Other means include shifting

investment toward mass transit, changing transportation pricing, and encouraging car

sharing, walking, and biking." (Cleveland National, supra, 3 Cal.5th at p. 506.)

Because the RTP must be internally consistent, the housing needs analysis and the

reductions in GHG emissions must work together to achieve the stated goals. (Gov.

Code, § 65080, subd. (b) ["The [RTP] shall be an internally consistent document"].)

However, the SCS is not the equivalent of a general plan. The SCS does not directly

require local government to take particular actions in planning, regulating, and permitting

land development. (Gov. Code, § 65080, subd. (b)(2)(K) ["Nothing in a[n SCS] shall be

interpreted as superseding the exercise of the land use authority of cities and counties

within the region."].)

40 Smart growth means "compact, efficient, and environmentally sensitive pattern of development that focuses future growth away from rural areas and closer to existing and planned job centers and public facilities, while preserving open space and making more efficient use of existing urban infrastructure."

85 Sen. Bill No. 375 requires the California Transportation Commission to establish

guidelines for an MPO to use in developing an RTP. (Gov. Code, § 14522.1, subd.

(a)(1).) These guidelines must take VMT into account:

"(b) The guidelines shall . . . account for all of the following:

"(1) The relationship between land use density and household vehicle ownership and vehicle miles traveled in a way that is consistent with statistical research.

"(2) The impact of enhanced transit service levels on household vehicle ownership and vehicle miles traveled." (Gov. Code, § 14522.1, subd. (b)(1) & (2).)

However, under Sen. Bill No. 375, a combination of factors and methodologies

may be used to achieve GHG reduction targets. Each percentage reduction in GHG

emissions assigned to a particular MPO does not require that same percentage reduction

in VMT. (Gov. Code, § 65080, subd. (b)(2)(A)(i).)

B. SANDAG's Regional Plan

As part of its mandate under Sen. Bill No. 375, SANDAG's target is to reduce the

region's per capita GHG emissions from cars and light trucks by 7 percent by 2020 (when

compared with a 2005 baseline), and 13 percent by 2035. To achieve these goals,

SANDAG developed an SCS as part of its RTP (Regional Plan).

The Regional Plan is organized around five strategies: (1) focus housing and job

growth in urbanized areas where there is existing and planned transportation

infrastructure, including transit; (2) preserve sensitive habitat, open space, cultural

resources, and farmland; (3) establish a transportation network that reduces GHG

86 emissions; (4) address housing needs of all economic segments of the population; and

(5) implement the regional plan through incentives and collaboration.

1. Housing

The Regional Plan states, "Land use decisions made at the local level can impact

nearly all sources of emissions . . . . Development guided by smart growth principles—

remember: more compact communities, less suburban sprawl—brings people closer to

more destinations. It also encourages alternative travel choices, such as public transit,

carpooling, walking and biking, which cut greenhouse gas emissions and other forms of

pollution."

The Regional Plan notes that "[d]uring the last 15 years, our jurisdictions have

changed their land use plans significantly, resulting in development patterns that

concentrate future growth in urbanized areas, reduce sprawl, and preserve more land for

open space and natural habitats." SANDAG states these were "seismic shifts" in thinking

about how to grow. The Regional Plan concludes that the "long-term plans for our local

cities and the County of San Diego now call for focusing new growth in the urbanized

areas of the western portion of our region where more people already live." By designing

communities that better integrate land use and transportation, the Regional Plan seeks to

"create more opportunities for developing a wider variety of travel choices beyond the

car . . . ."

SANDAG forecasts that the San Diego region will continue to grow more

sustainably. "More compact and efficient communities, paired with a greater variety of

transportation options and less sprawl, will result in preserved open space and habitat,

87 and a more efficient use of water and energy." New housing should be located "in urban

communities close to jobs and transit."

"While the western areas will grow over time through more compact communities,

more land in the eastern two-thirds of the region will be preserved as open space." The

Regional Plan encourages local jurisdictions in the region "to continue to embrace smart

growth and sustainable development" because "new growth and development in the most

urbanized areas of the region is a key strategy toward sustainability."

Sen. Bill No. 375 requires that areas be identified within the region sufficient to

house the region's entire population over the course of the planning period. The Regional

Plan forecasts needing 325,000 additional homes. The Regional Plan states that "[n]ew

housing should be located in urban communities close to jobs and transit." SANDAG

projects that 82 percent of homes to be built by 2050 will be attached multifamily units

mostly located where the greatest investments in public transit are being made.

Approximately 55 percent of the region will be preserved as open space and parks,

habitat, or farmland.

2. Transportation

The "heart" of the Regional Plan is an SCS that "charts a course toward lower

GHG emissions related to cars and light trucks, and proposes other measures to make the

San Diego region more environmentally sustainable." The SCS focuses on transportation

because "about a third of GHG emissions generated in this nation come from that sector

alone." Transportation is also the largest source of GHG emissions in the region. In

2012, passenger cars and light trucks comprised 37 percent of the region's GHG

88 inventory. Although the transportation sector is responsible for the greatest GHG

reductions (nearly 30 percent of the total), most of those reductions will come from

higher fuel efficiency vehicles (18 percent) and a more diverse fuel mix (low carbon fuel

standards) (9 percent). Statewide regional transportation plans are responsible for less

than three percent of the GHG reductions.

SANDAG states that its Regional Plan will exceed its CARB targets

"[b]y . . . using land in ways that make developments more compact, conserving open

space, and investing in a transportation system that provides people with alternatives to

driving alone." "Reducing the number of miles that people travel in their cars is an

important goal." "Fuel efficiency improvements and alternatives also comprise a major

part of" planned GHG emission reductions from the transportation sector.

The Regional Plan states that it will exceed CARB's goals, resulting in a 15

percent per capita reduction in emissions by 2020, and a 21 percent per capita reduction

by 2035—"far more than what the state mandates require . . . ." Approximately half of

the reductions would result from "investment in transit projects and their operations,

managed lanes, active transportation projects" and measures "that support . . . working

from home or telecommuting." "About one-quarter of the reductions are estimated from

changing land use and population characteristics, while another quarter are projected

from increases in the cost of driving . . . ."

89 C. The SEIR's Discussion of Consistency with Sen. Bill No. 375

1. The CAP

The SEIR states that the Project is consistent with the Regional Plan and with Sen.

Bill No. 375. With respect to the CAP, the SEIR states that GHG reduction measure

T.2.1 would "implement traffic calming measures," and measure T.2.2 would require

private employers to adopt a transportation demand management program.41 Measure

T-2.3 reduces County employee VMT by 20 percent by 2030. Parking restrictions in

measure T-2.4 reduce VMT by 10 percent by 2030. The SEIR concludes that

"[a]dditional supporting efforts for the built environment and transportation category" in

the CAP "would also encourage efforts to support the goals and policies of Sen. Bill

No. 375 and the [Regional Transportation Plan]/SCS." The CAP's numerous GHG

reduction measures will contribute 13 percent of GHG reductions needed to meet the

2030 target and 8 percent of the GHG reductions estimated for 2050. These include

41 Measure T-2.1 seeks to reduce VMT by making pedestrian and bicycle trips "a more comfortable and safer experience when traveling along public roads. Specific improvements may include marked crosswalks, countdown signal timers, speed humps, and protected bikeways. Measure T-2.2 states it will reduce emissions from commute VMT in new nonresidential development by 15 percent by 2030 by amending the County Code to include a Transportation Demand Management Ordinance requiring measures such as telecommuting, car sharing, vanpools, carpools, shuttle service, bicycle parking facilities, and transit subsidies. 90 (1) reducing VMT by acquiring open space, agricultural easements, and updating

community plans; (2) using alternative fuels in County projects and installing electric

vehicle charging stations; and (3) establishing a local direct investment program.

Summarizing its strategy to reduce VMT, the CAP states:

"The county's largest unincorporated communities are located in the western areas of the county, with access to water, sewer, roads, schools, and other public facilities. Focusing new development in and around existing unincorporated communities allows the County to maximize existing infrastructure . . . .

"This strategy focuses on preserving open space and agricultural lands, and focusing density in the county villages. Conservation efforts will avoid GHG emissions from transportation and energy use associated with conveyance of water and solid waste service. Reductions in Vehicle Miles Traveled (VMT) resulting from this strategy will also improve air quality through reduced vehicle emissions and contribute to public health improvements by creating opportunity for active transportation choices."42

The SEIR also concludes that the CAP is consistent with the Regional Plan's VMT

projections. The SEIR explains this is because the County provided SANDAG land use

forecasts based on the GPU. SANDAG, in turn, used these forecasts to make VMT

projections that achieve Sen. Bill No. 375 targets. The CAP uses these same VMT

forecasts for the GHG reduction measures. The SEIR concludes that the CAP's GHG

inventory is consistent with SANDAG's VMT projections, since both are based on

projected build-out under land uses allowed under the GPU.

42 "Active transportation choices" includes any method of travel that is human powered, such as walking and bicycling.

91 The SEIR acknowledges the "disproportionality" between the percentage of GHG

emissions attributable to the transportation sector (45 percent) and the lower percentage

of GHG emissions reductions attributable to CAP GHG reduction measures (13 percent).

The SEIR explains that disparity is the unavoidable result of the unincorporated county's

"low-density development" and "intervening distance between land uses."

2. M-GHG-1

The SEIR acknowledges that "several comments question how . . .

M-GHG-1 . . . addresses the consistency of future projects proposing a [GPA] with Sen.

Bill No. 375." The SEIR states that such projects "have the potential to result in a

significant cumulative GHG impact because they may adversely affect the ability of the

CAP to meet its targets and goal . . . ." Nevertheless, the SEIR explains that M-GHG-1 is

consistent with Sen. Bill No. 375 and the Regional Plan because (1) it is the GPA

applicant's responsibility (not the County's) to determine how the GPA affects VMT

projections and the region's ability to meet Sen. Bill No. 375 targets; and (2) it would be

"speculative" to "presuppose approval of future and proposed GPA projects, including the

GHG emissions and VMT from these future projects. The SEIR concludes, therefore,

that "M-GHG-1 would ensure that GPAs are mitigating their emissions such that they

would not conflict with the Regional Plan and Sen. Bill No. 375 targets . . . ."

D. The Plaintiffs' and the Amicus Attorney General's Contentions

Plaintiffs contend that "[t]he CAP, via M-GHG-1, creates a 'pathway' for future

GPAs to mitigate their emissions through the purchase of out-of-county carbon offsets, in

direct contradiction of Sen. Bill No. 375's instruction to reduce emissions from land use

92 development and transportation patterns." In a related argument, Plaintiffs assert that

"the SEIR does not fully address how facilitating sprawl development and increased

VMTs by authorizing out-of-County offsets would be consistent with the [Regional

Plan]."

Appearing as amicus curiae, the Attorney General amplifies these arguments,

noting that one of the GPAs, Harmony Grove Village South, will increase VMT by 11.5

million miles annually.43 Like Plaintiffs, the Attorney General asserts that the SEIR fails

as an informative document because "the SEIR does not even acknowledge that

[M-GHG-1] will foreseeably result in increased VMT, let alone provide a complete

analysis of its consistency with the SANDAG Plan."

E. The Consistency Finding is Not Supported by Substantial Evidence

1. Introduction

The SEIR concludes that M-GHG-1 is consistent with the Regional Plan and Sen.

Bill No. 375 targets, stating: "[I]ncorporation of M-GHG-1 would ensure that GPAs are

mitigating their emissions such that they would not conflict with the Regional Plan and

Sen. Bill No. 375 targets . . . ." Plaintiffs challenge this finding, asserting it is not

supported by substantial evidence and that as a result, the SEIR fails as an informational

document. We agree.

43 The Attorney General filed an amicus curiae brief under California Rules of Court, rule 8.200(c)(7).

93 An EIR must "discuss any inconsistencies between the proposed project

and . . . regional plans" including "regional transportation plans." (Guidelines, § 15125,

subd. (d).) This determination must be supported by substantial evidence. (See Oakland

Heritage, supra, 195 Cal.App.4th at p. 898.) "In reviewing the record for substantial

evidence, we presume the agency's findings are correct and resolve all conflicts and

reasonable doubts in favor of the findings." (Citizens for Positive Growth &

Preservation v. City of Sacramento (2019) 43 Cal.App.5th 609, 629.) Substantial

evidence in a CEQA case is "enough relevant information and reasonable inferences from

this information that a fair argument can be made to support a conclusion, even though

other conclusions might also be reached. . . . Substantial evidence shall include facts,

reasonable assumptions predicated upon facts, and expert opinion supported by facts."

(Guidelines, § 15384, subds. (a) & (b).)

2. The SEIR's consistency finding is not supported by substantial evidence

a. Improper analysis of GPAs

The SEIR's consistency finding is flawed because it makes unwarranted

conclusions about GHG impacts from GPAs. For example, the SEIR states that projected

GHG emissions from GPAs would be consistent with the Regional Plan because "the

County provided SANDAG land use forecasts based on the GPU, which SANDAG then

incorporated into the adopted Regional Plan" to create VMT projections that "align with

the 2011 GPU." The defect in this analysis is that by definition, land uses allowed under

the GPU do not include GPAs (which increase density or intensity of use beyond that

94 allowed under the GPU). Thus, if VMT projections are based on GPU land uses (as the

County claims), then necessarily those projections exclude VMT from in-process GPAs.

The County makes a similar error in contending that CAP GHG reduction

measures will reduce VMT as contemplated in the Regional Plan. The CAP's GHG

emission forecasts are based on land use allowed under the GPU only and assume that in-

process and future GPAs will mitigate GHG emissions to zero above CAP projections

under M-GHG-1. Therefore, the fact that the CAP itself is consistent with VMT

reductions in the SCS does not support a finding that VMT impacts by in-process and

future GPAs will be consistent with the Regional Plan.

b. The County's GPA arguments are misleading

Not only does the County make unwarranted conclusions about GHG impacts

from GPAs, but when the County does address VMT impacts from GPAs, its arguments

are misleading. For example, the County contends that the "SEIR also includes projected

GHG emissions from [GPAs] approved through the time of the draft SEIR and

reasonably foreseeable [GPAs] . . . which captured in broad strokes the GHG from VMT

associated with these cumulative projects." However, the CAP's GHG projections

include emissions only from those GPAs that the County had adopted between August

2011 and August 2017. In other words, those GHG projections exclude emissions from

the 21 in-process GPAs. The County's assertion that the SEIR includes GHG emissions

from "reasonably foreseeable" GPAs is true only if "reasonably foreseeable" excludes in-

process GPAs. Yet in its opening brief, the County concedes that in-process GPAs are

"reasonably foreseeable."

95 In a related argument, the County states that GPU policies designed to reduce

VMT also apply to GPAs. However, this too is misleading. Measures to reduce GHG

emissions for projects with land use consistent with the GPU are found in the CAP. To

the extent GPAs increase density or intensity of land use beyond that allowed under the

GPU, those projects do not mitigate GHG emissions under the CAP, but rather under

M-GHG-1. Indeed, in arguing that the CAP is consistent with the GPU, the County

insisted on this very point—that "GPAs are not part of the project emissions of the CAP

because they are part of the cumulative impact analysis in the SEIR." Therefore, the

County's assertion—that GPU policies designed to reduce VMT also apply to GPAs—is

true only to the limited extent that the GPA project's proposed land use is consistent with

the GPU.

The County also contends substantial evidence supports the SEIR's consistency

finding because "future General Plan amendments are not part of the Project . . . ."

However, the CAP is part of the Project—and the CAP's GHG emission projections

assume that in-process and future GPAs will implement M-GHG-1 to mitigate GHG

emissions to zero above CAP GHG targets.

c. The consistency finding is properly considered

Last, the County makes several arguments in an attempt to remove the entire issue

of consistency with the Regional Plan from the case.

First, the County contends Plaintiffs' argument improperly "conflate[s] VMTs with

GHG emissions." However, "Generally, vehicle miles traveled is the most appropriate

measure of transportation impacts." (Guidelines, §15064.3, subd. (a).) At oral argument,

96 the County also asserted that VMT is "just coming into play." However, VMT has often

been used in California's regulation of air quality and GHG impacts:

"California legislation related to air pollution began to refer to vehicle miles traveled measurements of traffic flows in the context of travel demand management in the 1990s. In 1988, enactment of [Assem. Bill No. 4420] (Sher) directed the California Energy Commission to study the potential impacts of global climate change on the state, including its transportation system.[] The Energy Commission's 1991 report, Global Climate Change: Potential Impacts and Policy Recommendation, suggested a broad range of policies and strategies for reducing greenhouse gases.[] The eighth of the Energy Commission's recommended strategies was 'Reducing vehicle miles traveled in personal vehicles, through promoting improved and expanded transportation alternatives, vehicle miles traveled fees, and other highway use fees. . . .' After publication of the California Energy Commission's 1991 report, reducing vehicle miles traveled was widely considered to be a potential regulatory means for greenhouse gas emission reduction." (Dorothy J. Glancy, Vehicle Miles Traveled and Sustainable Communities, 46 McGeorge L. Rev. 23, 52-53 (2014).)

The County next contends that the SCS "does not require VMT reductions." But

this assertion distorts the record. The Regional Plan states: "Reducing the number of

miles that people travel in their cars is an important goal for our Regional Plan" and that

"[l]and use decisions made at the local level can impact nearly all sources of emissions—

for better and for worse. Development guided by smart growth principles—remember:

more compact communities, less suburban sprawl—brings people closer to more

destinations. It also encourages alternative travel choices, such as public transit,

carpooling, walking and biking, which cut greenhouse gas emissions and other forms of

pollution."

97 The County further contends it is SANDAG's obligation to make the Regional

Plan consistent with the GPU, and not the SEIR's obligation to explain any

inconsistencies with the Regional Plan. This argument is untenable. Guidelines section

15125, subdivision (d) states that an EIR "shall discuss any inconsistencies between the

proposed project and applicable . . . regional plans."

Last, citing Environmental Council of Sacramento v. County of Sacramento (2020)

45 Cal.App.5th 1020 (Environmental Council of Sacramento), the County asserts that

CEQA does not require analysis of consistency with a sustainable communities strategy.

In that case, the plaintiff challenged an EIR for failing to address whether it was

consistent with the Sacramento Area Council of Government's (SACOG) metropolitan

transportation plans/sustainable communities strategy (MTP/SCS). The Court of Appeal

rejected that argument because plaintiff failed to (1) exhaust administrative remedies; and

(2) "cite any evidence that a project must be evaluated under CEQA for consistency with

an SCS." (Environmental Council of Sacramento, at p. 1037.) In contrast here, Plaintiffs

exhausted administrative remedies. The SEIR acknowledges that "[m]any comments"

expressed concern that proposed GHG reduction measures would not meet VMT

reduction targets established by SANDAG's RTP/SCS. Moreover, unlike Environmental

Council of Sacramento, here the SEIR does address consistency between the CAP and the

RTP/SCS.

Moreover, we disagree with the dicta in Environmental Council of Sacramento,

supra, 45 Cal.App.5th at page 1037 that CEQA does not require this consistency

analysis. Sen. Bill No. 375 requires regional planning agencies to include a sustainable

98 communities strategy in their regional transportation plans. (Gov. Code, § 65080,

subd.(b)(2)(B).) As noted, Guidelines section 15125, subdivision (d) provides that an

EIR "shall discuss any inconsistencies between the proposed project and . . . regional

plans. Such regional plans include . . . regional transportation plans." Accordingly,

CEQA requires analysis of "any inconsistencies" between the Project and the Regional

Plan.

d. The impact of CARB's 2017 Scoping Plan

The Regional Plan states, "Reducing the number of miles that people travel in

their cars is an important goal for our Regional Plan." One of the five Regional Plan

"building blocks" is implementing "measures designed to reduce the number of miles

people travel in their vehicles." The Regional Plan consistently emphasizes the necessity

for "[d]evelopment guided by smart growth principles . . . more compact communities,

less suburban sprawl" to reduce GHG emissions to Sen. Bill No. 375 targets. Thus, the

County's failure to analyze and disclose VMT impacts caused by GPAs threatens

achieving state-mandated GHG emission reduction targets.

The seriousness of this deficiency is underscored by the 2017 CARB Scoping

Plan, which is the state's blueprint for meeting GHG emission reduction targets. (Center

for Biological Diversity, supra, 62 Cal.4th at p. 220.) The Scoping Plan recognizes that

in the past, "development patterns have led to sprawling suburban neighborhoods, a vast

highway system, growth in automobile ownership, and under-prioritization of

infrastructure for public transit and active transportation." The Scoping Plan states,

"VMT reductions are necessary to achieve the 2030 target and must be part of any

99 strategy evaluated in this Plan." (Italics added.) The Scoping Plan emphasizes that

"California must reduce demand for driving" and "lower-VMT future development

patterns are essential to achieving public health, equity, economic, and conservation

goals."

"Local land use decisions play a particularly critical role in reducing GHG emissions associated with the transportation sector . . . .

"While the State can do more to accelerate and incentivize these local decisions, local actions that reduce VMT are also necessary to meet transportation sector-specific goals and achieve the 2030 target under [Sen. Bill No. 32.] Through developing the Scoping Plan, CARB staff is more convinced than ever that, in addition to achieving GHG reductions from cleaner fuels and vehicles, California must also reduce VMT." (Italics added.)

VMT reduction is an integral part of California's strategy to reach 2030 and 2050

GHG emission reduction targets. However, M-GHG-1 would potentially allow GPAs to

mitigate 100 percent of their in-County GHG emissions by purchasing out-of-County

(including international) originating offsets. In so doing, M-GHG-1 is inconsistent with

the Regional Plan because it ignores whether GPAs are located consistent with smart

growth policies.

e. Failure to fulfill informational role

" '[A]n EIR is required to provide the information needed to alert the public and

the decision makers of the significant problems a project would create and to discuss

currently feasible mitigation measures.' [Citation.] To fulfill the EIR's informational

role, the discussion of the mitigation measures must contain facts and analysis, not bare

conclusions and opinions. [Citation.] The level of detail CEQA requires in the EIR's

100 discussion of facts and analysis of the mitigation measures depends on 'whether the EIR

includes enough detail "to enable those who did not participate in its preparation to

understand and to consider meaningfully the issues raised by the proposed project.' "

(King & Gardiner Farms, LLC v. County of Kern (2020) 45 Cal.App.5th 814, 869.)

The SEIR fails to comply with these informational standards. For example, at one

place the SEIR claims no VMT analysis is even necessary because "M-GHG-1 would

ensure that GPAs are mitigating their emissions such that they would not conflict with the

Regional Plan and Sen. Bill No. 375 targets on this issue." This explanation—that it is

unnecessary to consider whether GPAs using M-GHG-1 will increase VMTs because

GPAs will use M-GHG-1—is meaningless.

In a response to a comment, the SEIR also states it is too "speculative" to

presuppose approval of future and proposed GPA projects, including the GHG emissions

and VMT from these future projects. But this argument is untenable because, as noted

ante in the cumulative impacts discussion, many of the in-process GPAs were well into

the planning process, and yet the SEIR does not analyze or discuss VMT impacts of any

of them. (See Banning Ranch, supra, 2 Cal.5th at pp. 938-939.) "[T]here was no

practical or reasonable barrier to [the] disclosure and inclusion" of projects currently

under an agency's own environmental review." (SFRG, supra, 151 Cal.App.3d at p. 74.)

Even if more precise information may be available during project-specific review, the

County must still provide reasonably obtainable information, or explain (supported by

substantial evidence) why it cannot do so. "[I]f known impacts are not analyzed and

101 addressed in a program EIR, they may potentially escape analysis in a later-tier EIR."

(Forest Foundation, supra, 17 Cal.App.5th at p. 440.)

V.

THE SEIR FAILED TO ANALYZE A REASONABLE RANGE OF ALTERNATIVES

A. Background

An EIR "shall describe a range of reasonable alternatives to the project . . . which

would feasibly attain most of the basic objectives of the project but would avoid or

substantially lessen any of the significant effects of the project, and evaluate the

comparative merits of the alternatives. An EIR need not consider every conceivable

alternative to a project. Rather, it must consider a reasonable range of potentially feasible

alternatives that will foster informed decisionmaking and public participation."

(Guidelines, § 15126.6, subd. (a).)

The SEIR analyzed four project alternatives:

1. A no-project alternative, which assumed the CAP, GPA, GHG thresholds, and Guidelines for Significance would not be implemented;

2. An "enhanced direct investment" alternative, in which the County would pursue the direct investment reduction measure (T-4.1) to a greater degree than currently proposed in the CAP, and without a renewable energy target;

3. A 100 percent renewable energy alternative that would implement the CAP with increased reliance on renewable energy to meet GHG reduction targets;

4. An alternative that would increase the solid waste diversion rate from 75 percent to 80 percent by 2030.

102 Although the CAP recognizes that on-road transportation is the largest source of

GHG emissions in the County (45 percent of the GHG inventory), no alternative

addresses VMT or transportation-related GHG emissions. Plaintiffs contend that the

County violated CEQA by failing to consider smart-growth alternatives aimed at

reducing VMT. As explained post, we agree.

B. The SEIR's Discussion of Project Alternatives is Deficient

The "core of an EIR is the mitigation and alternatives sections." (Citizens of

Goleta Valley, supra, 52 Cal.3d at p. 564.) An agency may not approve a project that

will have significant environmental impacts if there are feasible alternatives that would

substantially lessen those effects. (Pub. Resources Code, § 21002; Guidelines, §§ 15002,

subd. (a)(3), 15021, subd. (a)(2).)

" ' "There is no ironclad rule governing the nature or scope of the alternatives to be

discussed other than the rule of reason." [Citation.] The rule of reason "requires the EIR

to set forth only those alternatives necessary to permit a reasoned choice" and to

"examine in detail only the ones that the lead agency determines could feasibly attain

most of the basic objectives of the project." [Citation.] An EIR does not have to consider

alternatives "whose effect cannot be reasonably ascertained and whose implementation is

remote and speculative." ' [Citation.] A court will uphold the selection of project

alternatives unless the challenger demonstrates ' "that the alternatives are manifestly

unreasonable and that they do not contribute to a reasonable range of alternatives." ' "

(Forest Foundation, supra, 17 Cal.App.5th at p. 436.)

103 Examining alternatives begins with project objectives because it is these objectives

that a proposed alternative must be designed to meet. (San Franciscans for Livable

Neighborhoods v. City and County of San Francisco (2018) 26 Cal.App.5th 596, 632.)

The SEIR identifies these Project objectives:

1. Reduce community and County operations GHG emissions to meet 2020 and 2030 reduction targets, and provide a mechanism to meet the County's 2050 goal;

2. Identify GHG reduction strategies and measures that reduce GHG emissions from activities in the unincorporated areas;

3. Update the General Plan and GPU to incorporate and reflect the GHG reduction targets, strategies, and measures for the reduction of GHG emissions because of buildout of the General Plan;

4. Prepare a County baseline GHG emissions inventory, and analyze the potential growth of these emissions over time; and

5. Establish a comprehensive approach to reduce County GHG emissions by incorporating feasible and effective GHG emission reduction measures.

This court's decision in Forest Foundation, supra, 17 Cal.App.5th 413 is closely

on point and compels the conclusion that the SEIR's alternatives section violates CEQA.

Forest Foundation involved a program EIR for SANDAG's 2011 RTP/SCS (called the

2050 Regional Transportation Plan).44 (Forest Foundation, at pp. 421, 425.) That EIR

analyzed GHG emissions impacts for years 2020, 2035, and 2050. (Id. at p. 430.) The

44 The 2050 RTP/SCS was adopted in 2011 and included a sustainable communities strategy with transportation choices designed to reduce GHGs and meet state targets set following passage of Sen. Bill No. 375. SANDAG updated the 2050 RTP four years later, naming it the 2015 Regional Plan.

104 EIR analyzed seven project alternatives, none of which involved reducing VMT. (Id. at

pp. 435-436.) This court held that omitting "an alternative which could significantly

reduce total vehicle miles traveled is inexplicable given SANDAG's acknowledgement in

its Climate Action Strategy that the state's efforts to reduce greenhouse gas emissions

from on road transportation will not succeed if the amount of driving, or vehicle miles

traveled, is not significantly reduced." (Id. at p. 436.) The court noted that the Climate

Action Strategy explained that lowering VMT can be accomplished through improved

land use and transportation planning. (Ibid.) The Climate Action Strategy recommended

increased funding and system investments for public transit, increased service on existing

routes, and infrastructure upgrades. (Id. at pp. 436-437.) We concluded, "Given these

recommendations, their purpose, and their source, it is reasonable to expect at least one

project alternative to have been focused primarily on significantly reducing vehicle trips."

(Id. at p. 437.)

Like the Climate Action Plan discussed in Forest Foundation, supra, 17

Cal.App.5th 413, here too SANDAG states the "heart" of the RTP/SCS is to lower GHG

emissions "related to cars and light trucks" because "about a third of GHG emissions

generation" are attributable to "that sector alone." The 2015 RTP/SCS states, "Reducing

the number of miles that people travel in their cars is an important goal for our Regional

Plan." The Scoping Plan states, "VMT reductions are necessary . . . and must be part of

any strategy . . . ." CARB likewise states, "local actions that reduce VMT are also

necessary to meet transportation sector-specific goals and achieve the 2030 target under

Sen. Bill No. 32. . . . California must also reduce VMT." Indeed, CARB states, "It is

105 important that VMT reducing strategies are implemented early because more time is

necessary to achieve the full climate, health, social, equity, and economic benefits from

these strategies." Thus, CARB recommends that agencies "prioritize onsite design

features that reduce emissions, especially from VMT . . . within the project's region. . . ."

In light of this consistently clear mandate to reduce VMT to help achieve target

GHG emission reductions, it is reasonable to expect at least one project alternative in the

SEIR to have been focused primarily on significantly reducing VMT.45 (Forest

Foundation, supra, 17 Cal.App.5th at p. 437.) The SEIR's failure to do so is prejudicial

because it precludes informed public participation and decisionmaking. (Ibid.)

Citing In re Bay-Delta Programmatic Environmental Impact Report Coordinated

Proceedings (2008) 43 Cal.4th 1143 (Bay-Delta), the County contends that implementing

a smart-growth alternative would be inconsistent with project objectives, one of which is

to reduce GHG emissions from buildout of the General Plan, not an amended General

Plan. Bay-Delta involved a project to restore the Bay-Delta's ecological health and

improve management of Bay-Delta water for the various beneficial uses that depend on

it. (Id. at pp. 1151-1152.) The Supreme Court held the failure to examine a program

alternative requiring reduced water exports from the Bay-Delta was not an abuse of

45 In its response to the Attorney General's amicus brief, the County contends Forest Foundation is distinguishable because that case concerned SANDAG's plan to reduce GHG emissions from cars and light duty trucks. However, that reads Forest Foundation too narrowly. As here, the RTP in Forest Foundation also included a SCS designed to promote "a more sustainable future by integrating land use, housing, and transportation planning to create a more sustainable, walkable, transit-oriented, compact development patterns and communities . . . ." (Forest Foundation, supra, 17 Cal.App.5th at p. 429.)

106 discretion because that alternative would not achieve the objective of water supply

reliability. (Id. at pp. 1163-1166.) In other words, an agency need not discuss

alternatives that cannot achieve the project's underlying purpose. (Id. at p. 1165.)

Here, Project objectives include (1) "[r]educe community and County operations

GHG emissions . . . and provide a mechanism to meet the County's projected 2050 goal";

(2) "[i]dentify GHG reduction strategies and measures that reduce GHG emissions from

activities in the unincorporated areas"; (3) "[p]repare a County baselines GHG emissions

inventory, which includes community and County operations emissions, and analyze the

potential growth of these emissions over time"; and (4) establish a comprehensive

approach to reduce County GHG emissions by incorporating feasible and effective GHG

emission reduction measures." Bay-Delta is materially distinguishable because here, a

smart growth alternative is consistent with achieving Project objectives.

Moreover, it is impossible to take M-GHG-1 (and, therefore, GPAs) completely

out of the CAP. As noted ante, the CAP achieves GHG reduction targets only by

excluding from its projections in-process GPA GHG emissions above the CAP—on the

assumption that GPAs will mitigate to zero-above-the-CAP under M-GHG-1. As a

result, a project alternative based on reducing GHG emissions by implementing smart

growth policies affecting GPAs is broadly consistent with CAP objectives.

Further, the GPU "includes specific goals and policies aimed at reducing GHG

emissions including growing in a compact and efficient manner, using energy more

efficiently, harnessing renewable energy to power buildings, improving waste recycling,

and improving access to sustainable transportation." The CAP, which is based on

107 buildout under the GPU, recognizes that "[g]iven that the largest source of emissions in

the unincorporated county is the On-Road Transportation sector, the CAP proposes

several measures . . . to reduce the number and length of vehicle trips." Thus, there is no

conflict among (1) buildout under the GPU, (2) the CAP, and (3) an alternative that

would encourage smart growth and associated reduced VMT.

At oral argument, the County also asserted that the CAP is "not a land use plan,

but an emissions reduction plan" and, therefore, project alternatives should also be

focused on emission reduction, not land development as in a smart growth plan. This

argument is untenable, however, because the County overstates the purported distinction

between land use and GHG emissions. GHG emission reduction targeted by Assem. Bill

No. 32 and other legislation is concerned with human activities contributing to climate

change. To state the obvious, the amount of GHG emissions from agricultural land and

open space will be vastly different if that same land contains 14,000 homes, roads, and

infrastructure. Land use often drives GHG emission levels. Therefore, a smart growth

land use alternative is reasonably related to GHG emission reduction.

Also at oral argument, the County asserted that VMT reduction "was considered,"

noting that the "first two" CAP GHG reduction measures involve reducing VMT.

Counsel concluded, "When you're reducing VMT, you are offsetting an impact of a

proposed project . . . we have a plan that is already an emissions reduction plan and it

already includes VMT." However, on-road transportation accounts for 45 percent of the

County's greenhouse gas inventory (as of 2014) and produced 1,456,060 MTCO2e. Yet

the two CAP reduction measures counsel referenced are expected to collectively reduce

108 2030 GHG emissions by 8,101 MTCO2e, or less than 1 percent of the on-road

transportation sector's contribution. Therefore, contrary to the County's contention, VMT

reduction in the CAP is not tantamount to a smart growth project alternative.

Finally, although this argument is not entirely clear, the County also contends its

failure to include an alternative aimed at reducing VMT was compelled by this court's

decision in Sierra Club I, supra, 231 Cal.App.4th 1152. This argument is untenable.

Sierra Club I required the County to prepare the SEIR; however, we did not address the

CEQA-required content of the alternatives section in it.

VI.

THE COUNTY ADEQUATELY RESPONDED TO COMMENTS ON THE DEIR

A. Legal Principles

Guidelines section 15088, subdivision (a) requires the agency to prepare a written

response to "comments on environmental issues" from persons who reviewed the draft

EIR. For "significant environmental issues raised" in such comments, the agency must

"describe the disposition" of such issues (for example, revisions to the proposed project)

in a "good faith, reasoned analysis in response." (Guidelines, § 15088, subd. (c).)

"Conclusory statements unsupported by factual information will not suffice." (Ibid.)

However, "the level of detail contained in the response . . . may correspond to the level of

detail provided in the comment." (Ibid.) A response may be sufficient if it refers to parts

of the draft EIR that analyzes the environmental impacts raised by the comment. (City of

Irvine v. County of Orange (2015) 238 Cal.App.4th 526, 550 (City of Irvine).) "A

109 general comment can be adequately met with a general response" and "[r]esponses need

not be exhaustive." (Ibid.)

B. Comments, Responses, and Analysis

There are several hundred comments on the draft SEIR. The superior court

singled out three as having inadequate responses. The County's opening brief challenges

only these three rulings, and there is no cross-appeal challenging the adequacy of any

other responses to comments. We discuss each of these three rulings next.

Comment O-21-4: Sempra Services Corporation commented that the CAP focuses

too little attention on reducing GHG emissions from the transportation sector.

Response to Comment O-21-4: The County responded by stating, "Please see

Master Response 9 and 6." Master Response 6 states in part, "Several comments assert

that the County underutilizes opportunities to reduce emissions in the transportation

sector, comparing the contribution of emissions from the transportation sector (45

[percent]) to [the] proportion of overall reductions from the Built Environment and

Transportation category (13 [percent]). . . . [¶] The County acknowledges the

disproportionality. . . . However . . . the nature of the unincorporated county is low-

density development that is not conducive to non-driving trips. . . . In addition the

County has limited jurisdiction in controlling transportation emissions apart from land

use and infrastructure planning. . . . While the nature of trips will likely continue to be

personal vehicle based, the fuel source and emissions factors of those trips can be

modified by switching to renewable sources including electricity. . . . In an effort to be

responsive to these comments, the County has added Measure T-3.5 to install 2,040 Level

110 2 electric vehicle charging stations through public-private partnerships at priority

locations in the unincorporated county by 2030. Electrifying VMT allows for the use of

cleaner and renewable energy to power vehicles, and reduces GHG emissions associated

with gasoline-powered internal combustion engines. Investment in a larger charging

network than currently exists is needed to encourage EV use and achieve additional GHG

reductions beyond State goals."

Analysis of Response to Comment O-21-4: The response is adequate because it

directly addresses the question, explains the disparity between GHG emissions reduction

measures in transportation and electricity sectors, and describes revisions to the proposed

project (adding measure T-3.5) to address the objection. (Guidelines, § 15088, subd. (c).)

In ruling otherwise, the trial court erred by ignoring Master Response 6.

Comment O-22-19: The Sierra Club commented that the SEIR should include a

mitigation measure "of installing a car-parking system" that gives County employees

"more choice over how they spend their wages, while significantly reducing the

frequency of the choice of arriving at work in a single-occupancy vehicle."

Response to Comment O-22-19: The County determined that unbundling the cost

of parking from salaries would be infeasible because County employees work in diverse

locations where parking is either free and plentiful or expensive and rare. Calculating a

fair unbundled charge applicable to all County employees would be "virtually impossible

under these varied conditions." The response also explained that "to institute such a

policy would affect County employees' Terms and Conditions of Employment, which

would require negotiation and agreement for each of the County's nine labor unions . . . .

111 The majority of the County's employees are currently covered by collective bargaining

agreements, which are not open for negotiations until 2022. In addition, unbundling the

cost of parking would require both elimination of subsidies paid to some classes of

employees who park in paid lots, and charging employees who park for free in lots

owned by the County. This would potentially affect employee income. . . . [¶]

Additionally a policy to unbundle the cost of parking would need to be adopted for all

County facilities to ensure equal opportunities, benefits, and access for County

employees. However, this may have a disproportionate impact on employees that work

at facilities in more rural areas of the County, where there is no or limited public

transportation alternatives available."

Analysis of Response to Comment O-22-19: This response is adequate because it

explains why the lead agency's position disagrees with the recommendations and

objection raised in the comment. (Guidelines, § 15088, subd. (c).) The response contains

factual assertions (e.g., free or subsidized parking already provided; majority of County

employees under a collective bargaining agreement; unbundling parking would affect

employee compensation) and analysis based on those facts. The trial court erred in

determining that this response was too conclusory.

Comment L-4-3: SANDAG commented, "Please continue to take into

consideration consistency with guiding plans for the region. . . .

SANDAG . . . encourages smart, sustainable growth and reinforces principles set forth in

SANDAG's Regional Plan."

112 Response to Comment -L4-3: In response, the County stated, "Section 2.10.4.2 of

the Draft SEIR evaluated the CAP's consistency with guiding plans for the region."

Analysis of Response to Comment L-4-3: SANDAG's comment that the County

"take into consideration" consistency with regional guiding plans is simply an exhortation

to comply with law. No response was necessary.

VII.

ISSUES INVOLVING EXHAUSTION OF ADMINISTRIVE REMEDIES

"Exhaustion of administrative remedies is a jurisdictional prerequisite to

maintenance of a CEQA action." (Bakersfield Citizens, supra, 124 Cal.App.4th at

p. 1199.) " 'That requirement is satisfied if "the alleged grounds for noncompliance with

[CEQA] were presented . . . by any person during the public comment period provided by

[CEQA] or prior to the close of the public hearing on the project before the issuance of

the notice of determination." ' " (City of Long Beach v. City of Los Angeles (2018)

19 Cal.App.5th 465, 474.) " ' "To advance the exhaustion doctrine's purpose '[t]he ''exact

issue" must have been presented to the administrative agency. . . ." (Forest Foundation,

supra, 17 Cal.App.5th at p. 446.) The issue raised administratively must be

' "sufficiently specific" ' so that the agency has the opportunity to evaluate and

respond . . . ." (Ibid.)

A. The Challenge to the SEIR's Alternatives Analysis was Exhausted

The County contends that Plaintiffs did not adequately exhaust remedies with

respect to the SEIR's alternative projects analysis. However, a February 2018 letter from

Golden Door's attorneys to the County Board of Supervisors states in part, "The County

113 should also study a mitigation measure or alternative to limit General Plan Amendments

to areas identified by SANDAG as 'smart growth' areas . . . . [I]t is vital to locate

unplanned residential development in smart growth areas near transit and jobs. Changing

land use patterns must favor smart growth over sprawl to be consistent with the

RTP/SCS." (Italics added.) Raising similar issues, a January 2018 letter from Sierra

Club's attorneys to the San Diego Planning Commission cites Forest Foundation, supra,

17 Cal.App.5th 431 and states, " 'The omission of an alternative which could significantly

reduce total vehicle miles traveled is inexplicable given SANDAG's

acknowledgements . . . that the state's efforts to reduce greenhouse gas emissions from

on-road transportation will not succeed if the amount of driving, or vehicle miles

traveled, is not reduced.' "

The purpose of requiring exhaustion is to afford an agency an opportunity to

address contentions and possibly render litigation unnecessary. Here, that policy was

fulfilled when Plaintiffs urged the County to consider an "alternative" to limit GPAs to

"smart growth areas near transit and jobs" to be "consistent with the RTP/SCS."

Plaintiffs' attorneys even cited one of the leading cases supporting their position. This is

far from the perfunctory "skeleton showing" the County claims. Rather, Plaintiffs

reasonably alerted the County to consider whether the SEIR violated CEQA by failing to

analyze a smart-growth alternative aimed at reducing VMT.

B. Environmental Justice

Government Code section 65302 identifies required "elements" in a general plan.

These include, among others, housing, conservation, open space, and noise. Effective in

114 2017, the Legislature amended this statute to require "[a]n environmental justice

element . . . that identifies disadvantaged communities within the area covered by the

general plan . . . ." (Gov. Code, § 65302, subd. (h)(1) [Stats. 2016, ch. 587 (Sen. Bill

No. 1000), § 1.5].) The environmental justice element shall, among other things,

"[i]dentify objectives and policies to reduce the unique or compounded health risks in

disadvantaged communities by means that include, but are not limited to, the reduction of

pollution exposure, including the improvement of air quality . . . ." (Gov. Code, § 65302,

subd. (h)(1)(A).)

Addressing similar concerns, the California Environmental Protection Agency is

required to "[c]onduct its programs, policies, and activities that substantially affect

human health or the environment in a manner that ensures the fair treatment of people of

all races, cultures, and income levels, including minority populations and low-income

populations of the state." (Pub. Resources Code, § 71110, subd. (a).) And under Assem.

Bill No. 32, CARB "shall ensure that the greenhouse gas emission reduction rules,

regulations, programs, mechanisms, and incentives under its jurisdiction, where

applicable and to the extent feasible, direct public and private investment toward the most

disadvantaged communities in California . . . ." (Health & Safe. Code, § 38565.)

1. The SEIR

In the superior court, Plaintiffs asserted that the SEIR does not adequately evaluate

"impacts on environmental justice." The superior court agreed, ruling that the SEIR

"failed to address environmental justice" by making "no attempt to disclose the increased

health damage that could occur to the more vulnerable County residents (children, the ill,

115 and disadvantaged communities) from the project 'increasing nonattainment criteria

pollutants' . . . , or from not requiring GHG offsets to be obtained in-County."

In its opening brief, the County challenges this ruling—but only in a footnote

under a heading entitled, "Petitioners Did Not Exhaust on Two Claims, Which Are

Waived." That footnote states: "CEQA does not require environmental justice analysis."

In support, the County cites Public Resources Code section 21083.1 (courts "shall not

interpret this division or the state guidelines . . . in a manner which imposes procedural or

substantive requirements beyond those explicitly stated in this division or in the state

guidelines") and Berkeley Hillside Preservation v. City of Berkeley (2015) 60 Cal.4th

1086, 1107, which states, "[T]he purpose of this statute was to 'limit judicial expansion of

CEQA requirements.' " The footnote also asserts that "any unique adverse health burden

from application of M-GHG-1 on disadvantaged communities would be too speculative

to analyze as discussed in Section C.1, supra."

On review of a CEQA action, our role is generally the same as the trial court.

(State Water Resources Control Bd. Cases (2006) 136 Cal.App.4th 674, 836 (Water

Resources).) However, that means "only that we would not be bound by, or be required

to show any deference to, the trial court's conclusion" on the environmental justice issue.

(Ibid.) It does not mean that the County, as the appellant aggrieved by the trial court's

determination, is entitled to seek reversal by relegating an issue to argument in a footnote.

"Even when our review on appeal 'is de novo, it is limited to issues which have been

adequately raised and supported in [the appellant's opening] brief. [Citations.] Issues not

raised in an appellant's brief are deemed waived or abandoned.' " (Ibid.) To succeed

116 here, the County must first establish error. And even in a CEQA case, " '[t]he most

fundamental rule of appellate review is that an appealed judgment or order is presumed to

be correct.' [Citation.] It is the appellant who bears the burden of overcoming that

presumption.' " (Ibid., italics omitted.)

The County has forfeited this argument. (Hall v. Department of Motor Vehicles

(2018) 26 Cal.App.5th 182, 193 [argument in footnote forfeited]; Sabi v. Sterling (2010)

183 Cal.App.4th 916, 947 ["Footnotes are not the appropriate vehicle for stating

contentions on appeal."]; Holden v. City of San Diego (2019) 43 Cal.App.5th 404, 419-

420 [same, collecting cases].) Indeed, the County's challenge to the trial court's

environmental justice ruling is also forfeited because it is under a heading in the brief

challenging only administrative exhaustion. (Provost v. Regents of University of

California (2011) 201 Cal.App.4th 1289, 1294 ["we do not consider all of the loose and

disparate arguments that are not clearly set out in a heading and supported by reasoned

legal argument"].) These well settled rules of appellate practice are not mere

technicalities. They ensure that opposing parties are fairly apprised of contentions so as

to afford a full and fair opportunity to respond.

Although we have discretion to overlook this forfeiture, prudential concerns

militate against doing so here. Whether CEQA may in some circumstances require an

environmental justice analysis is at least reasonably arguable. (See generally, Alan

Ramo, Environmental Justice as an Essential Tool in Environmental Review Statutes: A

New Look at Federal Policies and Civil Rights Protections and California's Recent

Initiatives, 19 Hastings W.-N.W. J. Envt'l. L. & Policy 41, 42 (2013) [noting that "[t]he

117 California Attorney General's recent litigation involving . . . global warming emissions[]

affecting minority communities has sparked renewed interest in the relationship between

environmental review laws and the doctrine of environmental justice."].) However, the

County's brief lacks analysis from which our consideration of that issue could even

begin.46

2. Amendment to the General Plan

In the superior court, Golden Door asserted that when the County amended GPU

policy COS-20 and goal COS 20.1 in 2018, this triggered "a separate requirement" under

Government Code section 65302 to adopt an environmental justice element in the general

plan. The County contends Plaintiffs are precluded from making this assertion because it

was not first made "during the administrative process."

Assuming without deciding that the exhaustion doctrine applies to this non-CEQA

issue, it is unnecessary to consider it because Plaintiffs have abandoned the point in the

trial court. We have searched the trial court's 17-page single-spaced minute order and are

unable to find any ruling on Plaintiffs' claim that the amendments to COS 20 and COS

20.1 triggered the County's obligation to add an environmental justice element to the

general plan. In ruling on a complex case such as this one, many things may be

overlooked that would readily have been corrected had attention been called to them.

46 Except to the extent that this opinion has law-of-the-case and/or claim or issue preclusion effect, we do not express any opinion on whether CEQA requires environmental justice review.

118 Where the court neither rules nor reserves its ruling for later, the party pressing the point

must make some effort to have the court actually rule. "If the point is not pressed and is

forgotten, [the party] may be deemed to have waived or abandoned it . . . ." (People v.

Braxton (2004) 34 Cal.4th 798, 813.)47

C. Geographic Scope

Guidelines section 15130, subdivision (b)(3) provides that an EIR's cumulative

impacts analysis "should define the geographic scope of the area affected by the

cumulative effect and provide a reasonable explanation for the geographic limitation

used." Here, the SEIR states that the "cumulative impact analysis study area for GHG

emissions" is the "entire unincorporated county and County local government

operations." (Italics added.) The SEIR additionally states, "the issue of global climate

change is inherently a cumulative issue" and, therefore, the geographical scope of the

cumulative GHG analysis is global.

The superior court ruled that the SEIR violates CEQA by using "a geographic

scope that was inconsistent and alternated between a 'Countywide' geographic scope of

cumulative GHGs and a 'global' geographic scope." The court also determined that "the

issue of inconsistent geographic areas" was "exhausted."

47 Therefore, it is unnecessary to consider the County's argument that even if Government Code section 65302 required adding an environmental justice element to the General Plan, one was not required because "there were no disadvantaged communities in the unincorporated County" when the County prepared the SEIR. This disposition also renders moot the County's request for judicial notice of General Plan 2017 Guidelines published by the Office of Planning and Research.

119 The County contends this claim was never presented during administrative

proceedings. Plaintiffs do not address this issue in their appellate briefs.48 However, in

the trial court Golden Door asserted it raised the point in letters dated (1) January 16,

2018, expressing "concern[] about the CAP's mitigation measure for cumulative GHG

impacts caused by General Plan Amendment projects"; (2) February 8, 2018, raising

numerous objections to M-GHG-1; (3) February 13, 2018, objecting to various aspects of

M-GHG-1; and (4) September 25, 2017, asserting that the CAP must provide assurances

that the offset projects will achieve projected reductions.

To advance the exhaustion doctrine's purpose "[t]he 'exact issue' must have been

presented to the administrative agency . . . ." [Citation.] While ' "less specificity is

required to preserve an issue for appeal in an administrative proceeding than in a judicial

proceeding" ' . . . 'generalized environmental comments at public hearings,'

'relatively . . . bland and general references to environmental matters' [citation] or

'isolated and unelaborated comment[s]' [citation] will not suffice.' " (Sierra Club v. City

of Orange (2008) 163 Cal.App.4th 523, 535-536.) Here, the cited letters contain general

criticisms of and objections to M-GHG-1. But none states that the DSEIR violates

CEQA by having an inconsistent geographical scope. Accordingly, the trial court erred

in determining this issue was exhausted. Necessarily, therefore, the court should not have

48 We nevertheless consider the point because a respondent's failure to address an issue raised in the opening brief is not a concession. (Griffin v. The Haunted Hotel, Inc. (2015) 242 Cal.App.4th 490, 505.)

120 reached the merits. Accordingly, the ruling that the SEIR's cumulative GHG impacts

discussion contains an inconsistent and flawed geographical scope must also be reversed.

VIII.

ENERGY ISSUE RULING FORFEITED

The trial court ruled that the County "failed to analyze potential energy impacts

that may result from GPAs and strategies to reduce energy impacts on such project sites"

and also "failed to evaluate the reasonably foreseeable impacts on energy usage in

allowing increased VMTs in exchange for GHG reduction through offsets." In a footnote

in its brief, Golden Door contends the County has forfeited this issue on appeal by failing

to address it in the opening brief. The County asserts that Golden Door itself has

forfeited the waiver argument by making it only in a footnote.

Since the trial court's judgment is presumed correct, it is the appellant's burden to

establish error. (Water Resources, supra, 136 Cal.App.4th at p. 836.) The County's

failure to address the energy impacts ruling in its opening brief compels the conclusion

the trial court's ruling on that point must be affirmed.49

49 Golden Door also asserts (again, in a footnote) that the County did not raise any issue in its opening brief that M-GHG-1 is or is not mandatory. We agree with the County that it is unclear what Golden Door claims to be forfeited and, therefore, do not consider the point further.

IX.

INCONSISTENCY BETWEEN THE CAP AND SEIR

The SEIR must explain project impacts in a manner "reasonably calculated to

inform the public . . . ." (Sierra Club, supra, 6 Cal.5th at p. 520.) The CAP states that its

2014 inventory of GHG emissions does not include emissions from GPAs that were

adopted, but not constructed, as of 2014:

"Even though there were GPAs that were adopted between 2011 (adoption of 2011 General Plan Update) and 2014 (inventory baseline year), none of these GPAs were constructed by 2014 and; therefore, their GHG emissions are not included in the 2014 inventory. The 2014 inventory is based on emissions-generating activities that existed on the ground in 2014." (Italics added.)

However, a portion of the SEIR states that the CAP's GHG emissions inventory

includes GPAs adopted between August 2011 and March 28, 2017:

"[T]he Draft CAP's GHG inventory includes GPAs adopted between August 2011 (adoption of 2011 GPU) and March 28, 2017 (date at which the inventory technical reports were prepared)." (Italics added.)

These are inconsistent. The first states that the inventory excludes GPAs not

constructed by 2014. The second states that the inventory includes GPAs adopted by

March 2017.50

To avoid inconsistency, the County contends we should read "inventory" as used

in the first quotation (from the CAP) to mean projected future GHG emissions. This

50 We discovered this inconsistency on our own and invited supplemental briefs on the issue, which we have considered.

122 argument is untenable, however, because "inventory" is consistently used in the CAP and

elsewhere in the SEIR to mean existing emissions, not future projections.

X.

REMEDIES

For the first time in its reply brief, and citing Public Resources Code section

21168.9, the County contends that even if M-GHG-1 violates CEQA, we should

"nonetheless allow the CAP to stand under CEQA's provisions for severable remedies.51

The County asserts this remedy is particularly appropriate here because the CAP is not

"tainted by any CEQA violation found with respect to M-GHG-1" and "M-GHG-1 is not

required for the CAP . . . ." This argument fails for two reasons. First, the County has

forfeited this argument by not asserting it in the opening brief. "We will not ordinarily

consider issues raised for the first time in a reply brief. [Citation.] An issue is new if it

51 Public Resources Code section 21168.9 provides in part: "(a) If a court finds, . . . that any determination, finding, or decision of a public agency has been made without compliance with this division, the court shall enter an order that includes one or more of the following: [¶] (1) A mandate that the determination, finding, or decision be voided by the public agency, in whole or in part. [¶] . . . [¶] (3) A mandate that the public agency take specific action as may be necessary to bring the determination, finding, or decision into compliance with this division. [¶] (b) Any order pursuant to subdivision (a) shall include only those mandates which are necessary to achieve compliance with this division and only those specific project activities in noncompliance with this division. The order shall be made by the issuance of a peremptory writ of mandate specifying what action by the public agency is necessary to comply with this division. However, the order shall be limited to that portion of a determination, finding, or decision or the specific project activity or activities found to be in noncompliance only if a court finds that (1) the portion or specific project activity or activities are severable, (2) severance will not prejudice complete and full compliance with this division, and (3) the court has not found the remainder of the project to be in noncompliance with this division."

123 does more than elaborate on issues raised in the opening brief or rebut arguments made

by the respondent in respondent's brief. Fairness militates against allowing an appellant

to raise an issue for the first time in a reply brief because consideration of the issue

deprives the respondent of the opportunity to counter the appellant by raising opposing

arguments about the new issue." (American Indian Model Schools v. Oakland Unified

School Dist. (2014) 227 Cal.App.4th 258, 275-276.)

Moreover, even if not forfeited, we would reject the argument. " 'Directing an

agency to void its approval of the project is a typical remedy . . . for a CEQA violation.' "

(John R. Lawson Rock & Oil, Inc. v. State Air Resources Bd. (2018) 20 Cal.App.5th 77,

102.) As explained ante, to the extent the CAP's GHG emission projections for GPAs

assume mitigation to zero or net zero under M-GHG-1, the CAP's projection is

unsupported by substantial evidence. Severing the CAP from M-GHG-1 would not result

in "complete and full compliance" with CEQA and is, therefore, not authorized by Public

Resources Code section 21168.9, subdivision (b).

Citing POET, LLC v. State Air Resources Bd. (2013) 218 Cal.App.4th 681

(POET), the County contends the court should allow the CAP to remain in effect even if

M-GHG-1 is invalid. At oral argument, the County asserted that "all of the work that

went into the CAP is something that should be preserved."

We disagree. The CAP's strategies and measures are designed to reduce GHG

emissions for build-out under the GPU. The CAP does so by (1) calculating a baseline

GHG emissions level as of 2014; and (2) estimating future GHG emissions under a

124 business as usual standard; and (3) implementing state mandated GHG reduction targets.

If any one of these calculations is erroneous, the CAP fails to accomplish its purpose.

In addition to the inconsistency between the CAP and SEIR discussed ante in part

IX, the problem here is with the CAP's GHG projections. The projections assume that

in-process and future GPAs will mitigate to zero-above-the-CAP under M-GHG-1.

Because M-GHG-1 is invalid, these projections are not accurate. There is no assurance

that in-process and future GPAs will in fact mitigate to net zero. Thus, there is no

evidence that the CAP's reduction measures will achieve the stated reduction targets,

even for projects consistent with the GPU. In sum, it is impossible to surgically excise

M-GHG-1 from the CAP to produce a valid stand-alone climate action plan.

The County's reliance on POET is not persuasive. There, the CEQA project was a

statewide regulation concerning low carbon fuel standards. CARB's low carbon fuel

standards regulations satisfied "a vast majority of the applicable legal requirements, but

ran afoul of several procedural requirements . . . ." (POET, supra, 217 Cal.App.4th at

p. 697.) The appellate court determined that in the "extraordinary case" before it,

suspending the fuel standards regulations would do more environmental harm than

allowing them to remain in effect pending the completion of CARB's corrective action.

(Id. at pp. 697, 761.) Accordingly, the appellate court exercised its inherent equitable

authority to maintain the status quo and allow the regulations to remain operative. (Id. at

p. 761.)

Unlike POET, the CEQA defect in the CAP is not procedural. The CAP is

substantively flawed because its projections depend upon the validity of M-GHG-1 to

125 reduce GHG emissions for probable in-process and all future GPAs to zero-above-the-

cap, and M-GHG-1 itself is invalid under CEQA.

XI.

NO SPECIAL MASTER

Citing Legislature of California v. Reinecke (1973) 9 Cal.3d 166 and Wilson v. Eu

(1991) 54 Cal.3d 471, Golden Door asks us to appoint a special master to "work with all

interested parties to assure the County expeditiously prepares an adequate CAP and

accompanying SEIR . . . ." However, both cited cases involve legislative impasse in

enacting reapportionment plans. The Court intervened in those cases and appointed

special masters because the legislative impasse might continue indefinitely, the Court's

duty to ensure equal protection of the laws was implicated, and electoral rights would be

irretrievably lost if no action were taken. (Wilson, at p. 473.) Especially given the

existing injunction prohibiting the County from relying on M-GHG-1 during CEQA

review of GHG emissions impacts of development proposals on unincorporated County

lands, similar exigent circumstances are lacking here.

XII.

THE COURT DECLINES TO PROVIDE AN ADVISORY OPINION

Citing no authority, Sierra Club asks that we provide "a clear declaration that no

out-of-County offsets are permitted under the current General Plan. Sierra Club also asks

that we "further declare that before the County could reauthorize out-of-County offsets,

the County would have to adequately analyze the direct and cumulative impacts of such a

program under CEQA, determine that in-County reductions are not available and cannot

126 be made available through a County or APCD program, and conduct the appropriate

process to amend its General Plan."

Essentially, Sierra Club's request is for advisory opinions on mitigation measures

and environmental analysis not before us in this case. It remains to be seen how the

County will amend the CAP, the SEIR, and M-GHG-1 to comply with this opinion.

Accordingly, we decline to issue advisory opinions to forestall hypothetical events that

may never occur. (Teachers' Retirement Bd. v. Genest (2007) 154 Cal.App.4th 1012,

1044.)

XIII.

SUMMARY OF HOLDINGS

A. The 2018 Climate Action Plan (CAP)

The CAP is not inconsistent with the General Plan. Nevertheless, the judgment

requiring the County to set aside and vacate its approval of the CAP is affirmed because

the CAP's greenhouse gas emission projections assume effective implementation of

M-GHG-1, and M-GHG-1 is itself unlawful under CEQA. Except to the extent that (1)

the CAP is impacted by its reliance on M-GHG-1; and (2) the CAP's inventory of

greenhouse gases is inconsistent with the SEIR (see holding (C)(4) post), the CAP is

CEQA-compliant.

B. M-GHG-1 is Invalid under CEQA

Generally speaking, CEQA permits mitigation measures for GHG emissions to

include offsite measures, including purchasing offsets. However, M-GHG-1 violates

CEQA because M-GHG-1 does not require that (1) offset protocols meet Assem. Bill

127 No. 32 criteria as established in the California Code of Regulations, title 17, section

95972; (2) greenhouse gas emission reductions achieved are additional within the

meaning of Health and Safety Code section 38562, subdivisions (d)(1) and (d)(2) and

California Code of Regulations, title 17, section 95802, subdivision (a); and (3) offsets

originating outside California have GHG emissions programs equivalent to or stricter

than California's program.

Additionally, M-GHG-1 violates CEQA because (1) it would allow a project

applicant to offset 100 percent of its GHG emissions through offset projects originating

outside of California; and (2) it allows a County official to determine whether any

particular offset program is feasible and otherwise appropriate, with no objective criteria

to guide the exercise of that discretion. M-GHG-1, therefore, lacks performance

standards to ensure the mitigation goal will be achieved. Therefore, the judgment

directing the County to set aside and vacate its approval of the CAP and SEIR is

affirmed.

C. SEIR Holdings

1. The cumulative impacts analysis violates CEQA

The SEIR's cumulative impacts analysis violates CEQA because it excludes GHG

impacts from in-process GPAs.

2. The finding that M-GHG-1 is consistent with the Regional Plan is not supported by substantial evidence

128 The SEIR's finding that M-GHG-1 is consistent with the Regional Plan is not

supported by substantial evidence. Therefore, the County abused its discretion in

certifying the SEIR. (Golden Door I, supra, 27 Cal.App.5th at p. 901.)

3. The failure to analyze a smart-growth alternative

The SEIR violates CEQA because it fails to analyze a smart-growth alternative to

the Project.

4. Inconsistency with the CAP

The CAP and SEIR are inconsistent with each other. The CAP states that its 2014

inventory of GHG emissions excludes emissions from GPAs that were adopted, but not

constructed as of 2014. However, the SEIR states that the same inventory includes GPAs

adopted between August 2011 and March 28, 2017.

For these additional reasons, the judgment directing the County to set aside and

vacate its approval of the CAP and SEIR is affirmed.

5. Thirty-year shelf-life

The SEIR adequately discloses that M-GHG-1 requires offsets for only 30 years.

6. Response to comments

The County's response to comments on the DSEIR is adequate.

7. Geographic scope

The trial court erred in determining that the SEIR contains an inconsistent

geographic scope because Plaintiffs failed to adequately exhaust administrative remedies

on that issue (see below).

129 D. Exhaustion of Remedies

Plaintiffs adequately exhausted administrative remedies on all issues addressed by

the trial court except that of geographical scope.

E. Environmental Justice Holdings

The County has forfeited the argument that the trial court erred in determining that

the SEIR violates CEQA by failing to address environment justice impacts.

Plaintiffs have forfeited the argument that the 2011 amendment to the General

Plan triggered a separate requirement to adopt an environmental justice element in the

general plan.

F. Energy Impacts

The County has forfeited any argument that the trial court erred in determining

that the SEIR failed to adequately analyze impacts to energy from GPAs and increased

VMTs in exchange for GHG reduction through offsets.

G. No Special Master Nor Advisory Opinion

The court declines to (1) appoint a special master to oversee CEQA compliance on

remand; and (2) issue an advisory opinion regarding CEQA compliance.

DISPOSITION

The trial court erred in determining that (1) the CAP is inconsistent with the GPU;

(2) the County's response to comments violates CEQA; and (3) the SEIR has an

inconsistent geographical scope for cumulative impacts.

The trial court did not err in concluding that "during CEQA review of GHG

emissions impacts of development proposals on unincorporated County lands and the

130 issuance of any permits or entitlements for any General Plan amendment projects

approved on or after February 14, 2018, the County, its agencies, agents, employees,

representatives, supervisors, or other personnel should not have relied on Mitigation

Measure M-GHG-1, which is contained within the County of San Diego Supplement to

the 2011 General Plan Update Program Environmental Impact Report, dated January

2018."

The trial court also did not err in issuing a writ of mandate directing the County to

set aside and vacate the February 14, 2018, approvals of the 2018 Climate Action Plan

and the certification of the Final Supplemental Environmental Impact Report and

approvals listed as specified in the final judgment filed January 16, 2019.

Furthermore, the trial court did not err in issuing an injunction stating that during

review of GHG emission impacts of development proposals on unincorporated County

lands under CEQA, including the review of such impacts prior to the issuance of any

permits or entitlements for any General Plan amendment projects approved on or after

February 14, 2018, the County, its agencies, agents, employees, representatives,

supervisors, or other personnel, shall not rely on Mitigation Measure M-GHG-1.

Additionally, because M-GHG-1 is invalid under CEQA, the trial court did not err

in declaring that the February 2018 Climate Action Plan and the certification of the Final

SEIR to the 2011 General Plan Update Program EIR are legally inadequate and may not

be used to provide the basis for CEQA review of GHG impacts of development proposals

in the unincorporated County.

131 Because the final judgment is expressly based on findings and determinations

made in the trial court's December 24, 2018 minute order, on remand the trial court is

directed to (1) amend that minute order; (2) issue a new writ of mandate, injunction, and

judgment; and (3) conduct further proceedings—all of which are to be consistent with

this opinion. In the interests of justice, the parties shall bear their own costs on appeal.

134 "CAP Mitigation Measure M-GHG-1: The County shall require in-process and future GPAs to reduce their emissions to ensure that CAP emission forecasts are not substantially altered such that attainment of GHG reduction targets could not be achieved Project applicants for in-process and future GPAs could accomplish this through two options, as outlined below.

"Option 1 (No Net Increase): GPA project applicants shall achieve no net increase in GHG emissions from additional density above the 2011 GPU. Applicants shall be required in their respective CEQA documents to quantify the GHG emissions from their projects that exceed the GHG emissions for the 2011 GPU density or intensity forming the basis of the CAP emission forecasts (i.e., projections). This increase in emissions shall be reduced through onsite design features and mitigation measures and offsite mitigation, including purchase of carbon offset credits by the applicant. Applicants shall demonstrate compliance with relevant CAP measures as identified in the "CAP Consistency Review Checklist" in addition to all feasible onsite design features and mitigation measures. Offsite mitigation, including purchase of carbon offset credits, would be allowed after all feasible onsite design features and mitigation measures have been incorporated.

"For example, if 400 residential units were allowed under the 2011 GPU and a GPA proposes 500 residential units, the emissions for the additional 100 units would be calculated and offset through compliance with the CAP Consistency Review Checklist and additional feasible onsite measures and offsite measures, including the use of carbon offsets. The emissions associated with the allowable density of 400 units would be mitigated through compliance with the CAP Consistency Review Checklist.

"The County will consider, to the satisfaction of the Director of Planning Development Services (PDS), the following geographic priorities for GHG reduction features and GHG reduction projects and programs: 1) project design features/onsite reduction measures; 2) offsite within the unincorporated areas of the County of San Diego; 3) offsite within the County of San Diego; 4) offsite within the State of California; 5) offsite within the United States; and 6) offsite internationally.

"Geographic priorities would focus first on local reduction features (including projects and programs that would reduce GHG emissions) to ensure that reduction efforts achieved locally would provide co-benefits. Depending on the carbon offset credit utilized, co-benefits may include reductions in criteria air pollutants, toxic air contaminants, energy demand, water consumption, health benefits, social benefits, and economic benefits. The GPA applicant or its designee shall first pursue offset projects and programs locally within unincorporated areas of the County of San Diego to the extent such carbon offset credits are available and are financially feasible, as reasonably determined by the Director of PDS.

135 "If carbon offset credits are provided as mitigation, the GPA applicant, or its designee, shall purchase and retire carbon offsets in a quantity sufficient to offset the net increase from GHG emissions above the density or intensity allowed in the 2011 GPU. This includes all GHG emissions from construction (including sequestration loss from vegetation removal) and operations.

"For the net increase of construction and operations GHG emissions prior to County's issuance of the project's first grading permit (for construction GHG emissions) or first building permit (for operations GHG emissions) the GPA applicant, or its designee, shall provide evidence to the satisfaction of the Director PDS that the project applicant or its designee has purchased and retired carbon offsets credits in a quantity sufficient to offset the net increase of construction and operations GHG emissions generated by the project. Operations emissions may be offset in phases commensurate with the overall phasing of the project.

"Carbon offset credits must be purchased through any of the following: (i) a CARB-approved registry, such as the Climate Action Reserve, the American Carbon Registry, and the Verified Carbon Standard, (ii) any registry approved by CARB to act as a registry under the state's cap and trade program, (iii) through the CAPCOA GHG Rx and the SDAPCD, or (iv) if no registry is in existence as identified in options (i), (ii). or (iii) above, then any other reputable registry or entity that issues carbon offsets consistent with Cal Health & Saf. Code section 38562(d)(1)), to the satisfaction of the Director of PDS.

"Option 2 Net Zero: GPA project applicants shall reduce all project GHG emissions to zero to achieve no net increase over baseline conditions (carbon neutrality). Project emissions shall be reduced to zero through onsite design features and mitigation measures and offsite mitigation, including purchase of carbon offset credits by the applicant or its designee. Applicants shall demonstrate compliance with relevant CAP measures as identified in the 'CAP Consistency Review Checklist' before considering additional feasible onsite design features and mitigation measures. Offsite mitigation, including purchase of carbon offset credits would be allowed after all feasible onsite design features and mitigation measures have been incorporated.

"The County will consider to the satisfaction of the Director of Planning & Development Services (PDS), the following geographic priorities for GHG reduction features, and GHG reduction projects and programs: 1) project design features/onsite reduction measures; 2) offsite within the unincorporated areas of the County of San Diego; 3) offsite within the County of San Diego; 4) offsite within the State of California; 5) offsite within the United States; and 6) offsite internationally. "Geographic priorities would focus first on local reduction features (including projects and programs that would reduce GHG emissions) to ensure that reduction efforts achieved locally would provide co-benefits. Depending on the carbon offset credit

136 utilized, co-benefits may include reductions in criteria air pollutants, toxic air contaminants, energy demand, water consumption, health benefits, social benefits, and economic benefits. The GPA applicant or its designee shall first pursue offset projects and programs locally within unincorporated areas of the County of San Diego to the extent such carbon offset credits are available and are financially feasible, as reasonably determined by the Director of PDS.

"If carbon offset credits are provided as mitigation, the GPA applicant, or its designee, shall purchase and retire carbon offsets in a quantity sufficient to offset all GHG emissions from the project. This includes all GHG emissions from construction (including sequestration loss from vegetation removal) and operations.

"Prior to the County's issuance of the project's first grading permit (for construction GHG emissions) or first building permit (for operations GHG emissions) the GPA applicant, or its designee, shall provide evidence to the satisfaction of the Director of PDS that the project applicant or its designee has purchased and retired carbon offset credits in a quantity sufficient to offset all construction and operations GHG emissions generated by the project. Operations emissions may be offset in phases, commensurate with the overall phasing of the project.

"Carbon offset credits must be purchased through any of the following: (i) a CARB-approved registry, such as the Climate Action Reserve, the American Carbon Registry, and the Verified Carbon Standard, (ii) any registry approved by CARB to act as a registry under the state's cap and trade program, (iii) through the CAPCOA GHG Rx and the SDAPCD, or (iv) if no registry is in existence as identified in options (i), (ii). or (iii) above, then any other reputable registry or entity that issues carbon offsets consistent with Cal Health & Saf. Code section 38562(d)(1)), to the satisfaction of the Director of

PDS."
