EPA's Greenhouse Gas Emissions Reduction Results

In This Section

Executive Order (EO) 13514, signed on October 5, 2009, established fiscal year (FY) 2008 as the baseline year for federal agency greenhouse gas (GHG) emissions reporting. EPA estimated its combined FY 2008 Scope 1 and 2 GHG emissions to be 140,809 metric tons of carbon dioxide equivalent (MTCO2e).

In FY 2011, EPA’s combined Scope 1 and 2 GHG emissions totaled 140,437 MTCO2e—a decrease of 373 MTCO2e, or 0.3 percent, from its FY 2008 baseline GHG emissions.

In FY 2011, federal GHG accounting guidance allowed agencies to use green power and renewable energy certificate (REC) purchases to reduce reported Scope 2 GHG emissions. Because of the Agency’s extensive green power and REC purchases, EPA reduced its net reportable Scope 1 and 2 GHG emissions to 60,634 MTCO2e in FY 2011, which represents a reduction of 80,175 MTCO2e, approximately 57 percent, from its FY 2008 baseline GHG emissions.

EPA estimated its FY 2008 Scope 3 GHG emissions baseline to be 79,738 MTCO2e. In FY 2011, EPA's Scope 3 GHG emissions totaled 71,736 MTCO2e—a decrease of 8,002 MTCO2e, or 10.0 percent, from its FY 2008 baseline GHG emissions.

EPA's Combined Scope 1 and 2 Greenhouse Gas Emissions

EPA's scope 1 and 2 GHG emissions in FY 2008, FY 2010, and FY 2011, and its FY 2020 emissions target.


Note: EO 13514 does not require agencies to develop GHG emissions inventories for FY 2009. EPA elected not to compile a GHG emissions inventory for FY 2009.

EPA's Scope 3 Greenhouse Gas Emissions

EPA's Scope 3 GHG emissions in FY 2008, FY 2010, and FY 2011, and its FY 2020 emissions target.

Note: EO 13514 does not require agencies to develop GHG emissions inventories for FY 2009. EPA elected not to compile a GHG emissions inventory for FY 2009.

Carbon Neutral Facilities

The Robert S. Kerr Environmental Research Center in Ada, Oklahoma, is EPA's first carbon-neutral laboratory. A ground source heat pump (GSHP) system allows the laboratory to operate with minimal natural gas consumption for heating and reheat purposes. Starting with the April 2005 purchase of 3 million kilowatt hours (kWh) per year of wind power green tags and continuing with additional Agencywide green power contracts, EPA offsets the remaining conventional electricity use (e.g., pumps, fans, lights) by purchasing green power from sources that do not produce greenhouse gas (GHG) emissions. As a result of these practices, EPA considers the facility to be carbon-neutral due to its extremely small carbon footprint.

EPA's Gulf Ecology Division Laboratory in Gulf Breeze, Florida, is also a carbon neutral facility.
