Mandatory GHG Reporting - Reported Emissions
This page updated November 4, 2015
2014 GHG Emissions DataUnder California’s Regulation for the Mandatory Reporting of Greenhouse Gas Emissions (MRR), industrial sources, fuel suppliers, and electricity importers must report their annual GHG emissions to the California Air Resources Board (ARB). For reporters subject to the California Cap-and-Trade Program, submitted data are verified by an ARB-accredited independent third-party verifier.
The link below provides a summary spreadsheet of 2014 GHG emissions data reported under MRR for individual reporting facilities, electric power entities, and fuel suppliers. Prior years' annual data are archived under the Historical Emissions section below.

2008 to 2013 Historical Emissions DataThe annual GHG emissions data for the years 2008 through 2013 are provided below.
GHG emissions data reported between 2008 and 2010 were subject to slightly different applicability, calculation, methodology, and verification requirements.
Beginning with GHG emissions data reported in 2011, new reporting sectors were included and ARB included changes in methodologies to harmonize with the U.S. EPA reporting regulation. In addition, ARB included collection of additional data to support the Cap-and-Trade Program and required annual third-party verification for all GHG emissions data. When comparing data reported for years 2011 and onward with historical 2008-2010 data, there will be differences in the facilities listed, as well as the emissions and other data due to changes in methods and applicability.
