California's Mandatory Reported GHG Emissions for 2008
The California Air Resources Board (ARB) is making available to the public a summary of facility greenhouse gas emissions data reported pursuant to the California mandatory GHG emissions reporting program required by the 2006 California Global Warming Solutions Act (AB32).
Under the program, California's largest industrial GHG emitters were required to report their emissions for the first time in 2009.
The 2008 GHG emissions data represent the reported emissions from electricity retail providers and marketers and six industrial sectors: cement plants; oil refineries, hydrogen plants, and stationary combustion sources (emitting 25,000 metric tons CO2 or greater per year); and electricity-generating facilities and cogeneration facilities (≥1 megawatt generating capacity and emitting 2,500 metric tons CO2 or greater per year).
The emissions reported by facilities through the Mandatory Reporting Program represent approximately 40 percent of California's statewide greenhouse gas emissions.
