Compliance Offset Protocols
ARB has adopted the following Compliance Offset Protocols that may
be used to generate ARB offset credits. Projects may list under only
the most recent version, once effective. Livestock and Ozone Depleting
Substances offset projects listed on or after January 1, 2015 must use
the November 14, 2014 Compliance Offset Protocol and all associated
documents. U.S. Forest offset projects listed on or after November 1,
2015 must use the June 25, 2015 Compliance Offset Protocol and all
associated documents.

Compliance Offset Projects
All compliance offset projects must be developed according to ARB approved Compliance Offset Protocols. Offset Project Operators must list their offset projects with an approved Offset Project Registry to be eligible for ARB offset credits. Please see the Climate Action Reserve, American Carbon Registry, or Verified Carbon Standard webpages for information on proposed compliance offset projects. Once projects are issued ARB credits, information about the projects can be found on ARB's Offset Credit Issuance webpage.

Early Action Offset Credits
The
Cap-and-Trade Regulation allows for the transition of eligible existing
offset credits developed under approved voluntary quantification
methodologies to
ARB offset credits for use in the Cap-and-Trade Program.
Additional information about early action offset credits is available
on the Early
Action Offset Credit web page.
Offset
Credit Invalidation
Section 95985 of the Cap-and-Trade Regulation establishes a process for ARB to investigate and invalidate issued compliance offset credits.
Information related to invalidated offset credits can be found below.

Offset
Project Registries
The Cap-and-Trade Regulation allows ARB to approve Offset Project Registries to help administer parts of the Compliance Offset Program. Offset Project Registries must meet specific regulatory criteria to be approved under the regulation. Offset Project Registries will help facilitate the listing, reporting, and verification of offset projects developed using the Compliance Offset Protocols. However, only ARB can issue compliance offset credits for use in the Cap-and-Trade Program. For more information please see the Offset Project Registry web page.
Information and documentation for listed compliance offset projects can be viewed on the registry websites below.
Offset
Verification Program
The
Cap-and-Trade Regulation requires the third-party verification of all
GHG emission reductions or removal enhancements before any ARB offset
credits may be issued. Only ARB-accredited offset
verification
bodies and offset verifiers may provide offset verification services
under the Compliance Offset Program. More information about
offset verification, including a list of approved offset verifiers and
verification bodies,
may be found on the Offset
Verification Program web page.
Offset Project Operators
Offset Project Operators (OPOs) may use Compliance Offset
Protocols
to develop compliance offset projects under the Cap-and -Trade Program.
The Regulation includes specific requirements that OPOs must
meet
including listing offset projects, reporting GHG reductions and removal
enhancements annually, contracting with an ARB-accredited verification
body to conduct offset verification, and submitting attestations to
ARB. More information on specific requirements and compliance
offset projects can be found on the Offset
Project Operators web page.
Offset Project Listing Requirements for Native American Tribes
Tribes, because of their unique status as sovereign nations, must include a limited waiver of sovereign immunity that is legally binding under the Tribe’s laws as part of the offset project listing requirements to participate in the Compliance Offset Program. Tribes must meet the requirements of sections 95975(c)(1) through (5), and the requirements of section 95975(l) of the Cap-and-Trade Regulation before any offset project located on the categories of land specified in section 95973(d) of the Cap-and-Trade Regulation can be listed under ARB’s Compliance Offset Program. For more information please see the Offset Project Listing Requirements for Native American Tribes web page.
Forms
ARB has developed forms for use in the Compliance Offset Program. These forms may be used by program participants for submitting information related to listing, reporting, verification, and issuance of ARB offset credits. These forms can be found on the Compliance Offset Program Forms web page. In addition, each approved Offset Project Registry will make forms available on its own web page.
