EPA Data Show GHG Emission Declines in the U.S.S. Himmelstein | October 18, 2018
The 2017 greenhouse gas (GHG) data collected by the U.S. Environmental Protection Agency (EPA) Greenhouse Gas Reporting Program shows overall decreases across sectors. The total U.S. greenhouse gas emissions reported decreased by 2.7% from 2016 to 2017.
Emissions from large power plants declined 4.5% since 2016, and 19.7% since 2011.
In 2017, 2.91 billion metric tons of carbon dioxide equivalent (CO2e) were reported by direct emitters. The power plant sector was the largest contributor with 1.8 billion metric tons CO2e, followed by the petroleum and natural gas systems sector with 284 million metric tons (MMT) CO2e and the chemicals sector with 184 MMT CO2e (non-fluorinated and fluorinated chemicals combined).
The CO2 emissions reported for 2017 represent 90.7% of the GHGs reported for the year. Methane emissions represent 7.7% of reported 2017 GHG emissions, nitrous oxide represents 0.9% and fluorinated gases (HFCs, PFCs, SF6) represent 0.6%.
This is the seventh year of full data collection for most sectors under the program, and more than 8,000 large facilities reported 2017 GHG emissions to the EPA.
