Kentucky, Ohio, and West Virginia were among the 27 states challenging the Obama Administration’s Clean Power Plan, in oral arguments Tuesday before the U.S. Court of Appeals in Washington, D.C.
The CPP aims to reduce by about a third the power plant emissions of CO2, a greenhouse gas that scientists have identified as a major cause of climate change. The pollution reductions would come in phases over a little more than two decades.
In an unusual move that reflects the importance of the case, all of the court’s 10 judges heard a full day of arguments, rather than the usual panel of three.
Supporters say the EPA plan would spur investment in clean energy technology. Opponents, including West Virginia Senator Shelley Moore Capito, say it will drive up the price of electricity and hurt an already ailing coal industry.
