Quantification Materials

The Air Resources Board (ARB) 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).  For Fiscal Year (FY) 2013-14, some administering agencies developed interim GHG quantification methodologies in consultation with ARB.  For FY 2014-15, ARB prioritized the development of quantification methods based on program timelines, with an initial focus on programs using GHG emission reductions as part of the criteria to score projects in a competitive process.  The tables below provide links to the GHG quantification methods developed by ARB in consultation with administering agencies.  As the GGRF program continues, quantification methodologies for all programs will continue to be developed or updated and posted below as necessary.

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
To help us serve you better, please provide the following information: name and company/industry, contact information, and question or comment.
