Description: This report presents a chronology of major federal agency actions, mainly by the Environmental Protection Agencey (EPA), in the wake of Massachusetts v. EPA. In this case, the Court held that greenhouse gases (GHGs), widely viewed as contributing to climate change, constitute “air pollutants” as that phrase is used in the Clean Air Act (CAA). As a result, said the Court, the U.S. EPA had improperly denied a petition seeking CAA regulation of GHGs from new motor vehicles by saying the agency lacked authority over such emissions.
