Hacienda TOD Standards and Design Guidelines Initial Study Contributions to Greenhouse Gas Emissions State of California. Based upon the 2004 GHG inventory data compiled by the California Air Resources Board (GARB) for the California 1990 greenhouse gas emissions inventory, California emitted 484 million metric tons of CO, equivalent (MMTCO,E), including emissions resulting from out -of -state electrical generation (CARB 2007). California is estimated to be the second largest emitter of greenhouse gases in the country, and is the 12th to 16th largest emitter of greenhouse gasses worldwide. A California Energy Commission (CEC) emissions inventory report placed CO, produced by fossil fuel combustion in California as the largest source of GHG emissions in 2004, accounting for 81 percent of the total GHG emissions (CHIC 2006). CO, emissions from other sources contributed 2.8 percent of thc total GHG emissions, methane emissions 5.7 percent, nitrous oxide emissions 6.8 percent, and thc remaining 2.9 percent was composed of emissions of other gases comprised primarily of refrigerants and a small contribution of sulfur hexafluoridc (SF6) used as insulating materials in electricity transmission and distribution (C EC 2006). San Francisco Bay Area and Alameda County. In December 2008, the Bay Arca Air Quality Management District (BAAQMD) published an inventory of GHG emissions in thc Bay Area for the base year 2007. Total Bay Area GHG emissions in 2007 were estimated at 102.6 MMTCO,E. Alameda County GHG emissions in 2007 were estimated at 17.7 MMTCO,E. (BAAQMD 2008). The primary contributors to GHG emissions in the San Francisco Bay Area and in Alameda County arc transportation, industry, and electric power generation. These and other primary contributors to the GHG emissions of the San Francisco Bay Area and Alameda County are presented in Table 1, GHG Sources in thc San Francisco Bav Area and Alameda County.
