California Greenhouse Gas Emissions Inventory Program
CARB prepares California’s Assembly Bill (AB) 32 (Nuñez and Pavley, Chapter 488, Statutes of 2006) Greenhouse Gas Emissions Inventory (AB 32 GHG Inventory) report annually using methods consistent with international practices. This report estimates anthropogenic GHG emissions within California, as well as emissions associated with imported electricity, by sector and gas over time. Changes in carbon stocks in California’s natural and working lands (NWL) are tracked in CARB’s NWL Carbon Inventory. The AB 32 GHG Inventory is one tool to track the state’s progress toward achieving GHG limits, in concert with data collected through various California Global Warming Solutions Act (AB 32) programs.
