In a last-minute slap at President Donald Trump, a federal appeals court struck down one of his administration’s most momentous climate rollbacks on Tuesday, saying officials acted illegally in issuing a new rule that eased federal regulation of air pollution from power plants.
The Trump administration rule was based on a “mistaken reading of the Clean Air Act,” the U.S. Court of Appeals for the District of Columbia ruled, adding that the Environmental Protection Agency "fundamentally has misconceived the law.” The decision is likely to give the incoming Biden administration a freer hand to regulate emissions from power plants, one of the major sources of climate-damaging fossil fuel emissions.
