U.S. Emissions

U.S. net emissions declined 11.5 percent from 2005 to 2015 due to a range of market- and policy-related factors. Electric power sector emissions fell 21 percent as a result of a shift from coal to natural gas, increased use of renewable energy, and a leveling of electricity demand. Improved vehicle efficiency helped reduce transportation-related emissions by nearly 10 percent, although transportation emissions have been increasing since 2012.

C2ES analysis projects that by 2025, U.S. emissions could be 14 percent to 18 percent below 2005 levels, far less than what is needed to address climate change.
