Proposed Clean Power Plan rule cuts power sector CO2 emissions to lowest level since 1980s

In June 2014, the U.S. Environmental Protection Agency (EPA) proposed a rule to regulate carbon dioxide (CO2) emissions from existing power plants under section 111(d) of the Clean Air Act. EIA's newly released analysis of the proposed rule shows power sector CO2 emissions falling to about 1,500 million metric tons per year by 2025, a level not seen since the early 1980s, in the Base Policy case.
