GHG Inventory Data Archive

CARB's GHG inventory is updated annually to include additional years and improved estimation methods. This website provides a repository of data and documentation for all past versions of the GHG inventory. These resources are provided for archive purposes only; please use the most current version of the GHG inventory data and documentation.

Global Warming Potentials for Past Inventory Versions

Global warming potentials (GWPs) are used to convert mass emissions to carbon dioxide equivalent values (CO₂e). These values are designated by the intergovernmental panel on climate change (IPCC), and are updated periodically to reflect advances in scientific knowledge. Second assessment report (SAR) GWPs were used in some past inventories, while the current inventory uses fourth assessment report (AR4) GWPs. A table of SAR and AR4 GWP values and a further discussion can be found on the GWP page.

2007 Edition: Years 1990-2004

GHG emissions prior to 2000 are included in the 1990-2004 GHG Emission Inventory published in November 2007 (data available at 1990 Level & Limit), which provided the basis for developing the 1990 statewide emissions level and 2020 emissions limit required by the Global Warming Solutions Act of 2006 (AB 32).
