The Clean Power Plan, one of President Obama’s main climate initiatives, was recently challenged in a federal appeals court by a coalition of energy and fossil fuel companies. The lawsuit sought for the court to assess the Plan’s legality. However, the U.S. Court of Appeals for the District of Columbia found the challenge pre- mature because the rules of the Plan are not yet final. Through the Plan, the EPA ultimately hopes to set a separate carbon-cutting goal for each state based on current emissions and capacity. Though even the Pres- ident acknowledges that executing the Plan will be “tough,” he and the EPA believe that carbon pollution in the U.S. must be cut.
