Quantification Materials



The California Air Resources Board (CARB) is required to develop quantification methods for agencies receiving Greenhouse Gas Reduction Fund (GGRF) appropriations per SB 862 (Senate budget and Fiscal Review Committee, Chapter 36, statutes of 2014).  All California Climate Investments (CCI) must reduce greenhouse gas (GHG) emissions. CARB is responsible for providing guidance on quantifying GHG emission reductions and co-benefits from all CCI projects.  The table below provides links to CARB quantification methodologies and calculator tools developed in consultation with administering agencies through a public process.  CARB staff periodically update methodologies to make them more robust, user-friendly, and appropriate to the projects being quantified.

In addition to GHG emission reductions, FY 2017-18 quantification methodologies are being developed to also estimate other benefits and key variables.  New or updated methodologies will be posted below as necessary.  CARB continues to develop methods to assess additional social, economic, and environmental co-benefits achieved by CCI projects. More information on CCI co-benefits, including assessment methods can be found at: www.arb.ca.gov/cci-cobenefits.

Note: These quantification methods have been developed specifically for the Greenhouse Gas Reduction Fund Programs and are not intended for use in other programs.


For questions about any of the quantification methods below, please email us at GGRFProgram@arb.ca.gov.  To help us serve you better, please provide the following information: name and company/industry, contact information, and question or comment.

Emission Factor Database:

In an effort to increase transparency and continue to use the most up to date emission factors when estimating CCI project benefits, CARB released a single repository for GHG and co-benefit emission factors used in quantification methodologies.  The CCI Quantification Methodology Emission Factor Database and Documentation below include emission factors used in CARB quantification methodologies released after August 30, 2017.  CARB will add emission factors and documentation applicable to CCI programs as FY 2017-18 methodologies become available.
Archived versions of the Database and Documentation can be found at:
