EPA Uses Uniform Standards To Preserve Overall Stringency In Final ESPS

EPA officials say they were able to strengthen their just-finalized greenhouse gas (GHG) rule for existing power plants despite dropping energy-efficiency measures from setting state goals due to more robust assumptions about the potential for renewable energy, as well as a more regional approach to coal-to-gas shifting. The regional target-setting approach is a major change to how EPA calculates states' GHG goals in the existing source performance standards (ESPS). Under the new approach, EPA created uniform emission performance rates for...
