Affordable Clean Energy Rule Delivers on Promise to Repeal Clean Power Plan

The U.S. Environmental Protection Agency (EPA) has delivered on the Trump administration’s promise to repeal the Obama-era Clean Power Plan (CPP), which would have imposed strict limits on greenhouse gas emissions from existing power plants, including mandating changes beyond the plants’ fence lines. The final Affordable Clean Energy (ACE) rule, issued on June 19, 2019, repealed and replaced the CPP requirements, which the Supreme Court prevented from taking effect in a 2016 ruling. The ACE’s final reversal of the CPP gives new life to the lingering national debate about how far EPA should go in limiting power plant emissions.
