Greenhouse Gas Reporting Program Data for Calendar Year 2010

EPA has released greenhouse gas (GHG) data reported from large facilities and suppliers across the U.S. economy for the year 2010.

Key Findings:

• (Traditional - Not including Geothermal) Power plants were the largest stationary source of direct U.S. GHG emissions with 2,324 million metric tons of CO2e, followed by refineries with 183 million metric tons of CO2e.
• CO2 emissions accounted for largest share of direct emissions with 95 percent, followed by methane with 4 percent, and nitrous oxide and fluorinated gases representing the remaining 1 percent.
• 100 facilities each reported emissions over 7 million metric tons of CO2e, including 96 power plants, 2 iron and steel mills and 2 refineries.

Geothermal power production has a significant environmental advantage over burning fossil fuels for electrical power production. Electrical production from geothermal fluids results in an order of magnitude less CO2 per kilowatt-hour of electricity produced compared to burning fossil fuels. 

The 2010 GHG data includes public information from facilities in 9 industry groups, including 29 source categories, which directly emit large quantities of GHGs, as well as suppliers of certain fossil fuels and industrial gases.

This information can be used to help businesses track emissions and identify cost– and fuel–saving efficiencies, identify industry leaders, inform policy at the state and local levels, and provide important information to the finance and investment communities.
