The rules are finally out. In what some pundits are calling the most important act of President Obama’s second term, on Monday morning the EPA released its “Clean Power Plan.” These are the proposed rules that will require reductions in greenhouse gas emissions from existing electric power plants. Electric generation accounts for about 40 percent of current U.S. CO2 emissions.
The text of the regulations runs to 645 pages, and it isn’t exactly a page-turner. We suspect you’ve got more fun things to do with your time on this lovely spring day than to read it. So here we answer the nine most important questions about the proposal for you:
1. What will the rules do? The EPA intends to create a “rate-based” limit on greenhouse gas emissions from power plants for each state depending on its current emissions. Rate-based means it sets a standard for how much CO2 is emitted per megawatt hour of electricity produced, not a limit on total carbon tonnage. The plan is designed, as was expected, to give states maximum flexibility to meet these goals in whichever way works best for them and to avoid constricting economic growth. States can, however, choose to convert their rate-based goal into a total tonnage goal if they prefer.
2. How much will the plan cut emissions?
