EPA: US GHG emissions in 2017 down 0.3% from 2016

Green Car Congress

above 1990 levels in 2007. The decrease in CO 2 emissions from fossil fuel combustion was a result of multiple factors, including a continued shift from coal to natural gas, increased use of renewables in the electric power sector, and milder weather that contributed to less overall electricity use. Overall, net emissions in 2017 were 12.7%
