GHGs and Where They Are
In January 2012, for the first time, the U.S. Environmental Protection Agency (EPA) released greenhouse gas (GHG) data collected under the GHG Reporting Program. GHG is primarily Carbon Dioxide but includes many other other chemicals such as methane. The data shows 2010 U.S. GHG emissions from large industrial facilities, and from suppliers of certain fossil fuels and industrial gases. Reporting entities used uniform methods for estimating emissions, which enables data to be compared and analyzed. The data shows the larger GHG emitters are power plants followed by petroleum refineries. GHG data are now easily accessible to the public through the EPA’s GHG Reporting Program. The 2010 GHG data to be released includes public information from facilities in nine industry groups that directly emit large quantities of GHGs, as well as suppliers of certain fossil fuels and high global warming gases.
The EPA GHG data does not show all possible GHG emissions; only those associated with large sources are shown. The major sources tend to be clustered in the midwest, northeast, and Texas.
Power plants represent over 70% of these emissions. Refineries come in as a distant sedond around 6% followed by chemicals and industrial sources each of around 5%.
