Update to the Greenhouse Gas Inventory

Welcome to the California Energy Commission

Update to the Greenhouse Gas Inventory
DOCUMENTS PAGE

Please note:

The California Global Warming Solutions Act of 2006 requires the Air Resources Board (ARB) to determine the statewide 1990 greenhouse gas (GHG) emissions level as a statewide aggregate emissions limit to be achieved by 2020. Under separate statutory authority, on January 1, 2007, ARB received responsibility for maintaining the Statewide GHG emissions inventory from the California Energy Commission.

The latest ARB GHG inventory report can be found at: http://www.arb.ca.gov/cc/ccei/emsinv/emsinv.htm
