"On October 10, 2017, the U.S. Environmental Protection Agency (EPA) proposed to repeal the Clean Power Plan (CPP), an Obama Administration rule that would limit carbon dioxide (CO2) emissions from existing fossil-fuel-fired power plants. Because power plant CO2 emissions account for about 30% of total U.S. anthropogenic emissions of greenhouse gases (GHGs), the CPP has been seen as the most important U.S. regulation addressing climate change. [...] Members of Congress may have an interest--for legislative and oversight purposes, as potential commenters, and in responding to constituents--in understanding what it is that EPA has proposed to do with regard to the CPP. This report provides background on the CPP and its proposed repeal, describes the administrative steps that are required to repeal or amend a rule, and discusses how the CPP and its proposed repeal fit into the context of recent and projected power sector evolution."
