The two previous California 2020 greenhouse gas (GHG) emissions forecasts used in the AB 32 Scoping Plan (2008) and for the Cap & Trade Regulation (2010) are archived below. These forecasts were used to assess the GHG reductions necessary to return California to 1990 emission level based on the GHG inventories published by ARB in support of its programs. California's current 2020 GHG emissions forecast is available on the current forecast page.
