U.S. energy-related carbon dioxide (CO2) emissions in 2016 totaled 5,170 million metric tons (MMmt), 1.7% below their 2015 levels, after dropping 2.7% between 2014 and 2015. These recent decreases are consistent with a decade-long trend, with energy-related CO2 emissions 14% below the 2005 level in 2016.
As noted in a recent article on energy use, both oil and natural gas consumption were higher in 2016 than in 2015, while coal consumption was significantly lower. Consistent with changes in fuel consumption, energy-related CO2 emissions in 2016 from petroleum and natural gas increased 1.1% and 0.9%, respectively, while coal-related emissions decreased 8.6%.
