(a) Lead agencies
may analyze and mitigate the significant effects of greenhouse gas emissions at
a programmatic level, such as in a general plan, a long range development plan,
or a separate plan to reduce greenhouse gas emissions. Later project-specific
environmental documents may tier from and/or incorporate by reference that
existing programmatic review. Project-specific environmental documents may rely
on an EIR containing a programmatic analysis of greenhouse gas emissions as
provided in section
15152 (tiering), 15167 (staged
EIRs) 15168 (program EIRs), 15175-15179.5 (Master EIRs), 15182 (EIRs Prepared
for Specific Plans), and 15183 (EIRs Prepared for General Plans, Community
Plans, or Zoning).
(b) Plans for the
Reduction of Greenhouse Gas Emissions. Public agencies may choose to analyze
and mitigate significant greenhouse gas emissions in a plan for the reduction
of greenhouse gas emissions or similar document. A plan to reduce greenhouse
gas emissions may be used in a cumulative impacts analysis as set forth below.
Pursuant to sections
15064(h)(3) and
15130(d), a lead
agency may determine that a project's incremental contribution to a cumulative
effect is not cumulatively considerable if the project complies with the
requirements in a previously adopted plan or mitigation program under specified
circumstances.
(1) Plan Elements. A plan for
the reduction of greenhouse gas emissions should:
(A) Quantify greenhouse gas emissions, both
existing and projected over a specified time period, resulting from activities
within a defined geographic area;
(B) Establish a level, based on substantial
evidence, below which the contribution to greenhouse gas emissions from
activities covered by the plan would not be cumulatively
considerable;
(C) Identify and
analyze the greenhouse gas emissions resulting from specific actions or
categories of actions anticipated within the geographic area;
(D) Specify measures or a group of measures,
including performance standards, that substantial evidence demonstrates, if
implemented on a project-by-project basis, would collectively achieve the
specified emissions level;
(E)
Establish a mechanism to monitor the plan's progress toward achieving the level
and to require amendment if the plan is not achieving specified
levels;
(F) Be adopted in a public
process following environmental review.
(2) Use with Later Activities. A plan for the
reduction of greenhouse gas emissions, once adopted following certification of
an EIR or adoption of an environmental document, may be used in the cumulative
impacts analysis of later projects. An environmental document that relies on a
greenhouse gas reduction plan for a cumulative impacts analysis must identify
those requirements specified in the plan that apply to the project, and, if
those requirements are not otherwise binding and enforceable, incorporate those
requirements as mitigation measures applicable to the project. If there is
substantial evidence that the effects of a particular project may be
cumulatively considerable notwithstanding the project's compliance with the
specified requirements in the plan for the reduction of greenhouse gas
emissions, an EIR must be prepared for the project.
(c) Special Situations. As provided in Public
Resources Code sections
21155.2
and
21159.28,
environmental documents for certain residential and mixed use projects, and
transit priority projects, as defined in section 21155, that are consistent
with the general use designation, density, building intensity, and applicable
policies specified for the project area in an applicable sustainable
communities strategy or alternative planning strategy need not analyze global
warming impacts resulting from cars and light duty trucks. A lead agency should
consider whether such projects may result in greenhouse gas emissions resulting
from other sources, however, consistent with these
Guidelines.
