The comprehensive greenhouse gas (GHG) data reported directly from large facilities and suppliers in the US are now accessible to the public through EPA’s GHG Reporting Program. The 2010 GHG data includes public information from facilities in nine industry groups that directly emit large quantities of GHGs, as well as suppliers of certain fossil fuels. EPA’s online data publication tool allows users to view and sort GHG data for calendar year 2010 from over 6,700 facilities by facility, location, industrial sector, and the type of GHG emitted. Most reporting entities submitted data for calendar year 2010. However, an additional 12 source categories will begin reporting their 2011 GHG data this year.
In summary, GHG data for direct emitters show that in 2010:
- Power plants were the largest stationary sources of direct emissions with 2,324 million metric tons of carbon dioxide equivalent (mmtCO2e), followed by petroleum refineries with emissions of 183 mmtCO2e.
- CO2 accounted for the largest share of direct GHG emissions with 95 %, followed by methane with 4 %t, and nitrous oxide and fluorinated gases accounting for the remaining 1 %.
- 100 facilities each reported emissions over 7 mmtCO2e, including 96 power plants, two iron and steel mills and two refineries.
