CARB updates Quantification Material Website to include co-benefits

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 air pollutant emissions and other 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.
