Federal Agency Actions Following the Supreme Court's Climate Change Decision: A Chronology

Federal Agency Actions Following the Supreme Court's Climate Change Decision: A Chronology

Date: December 23, 2010
Creator: Meltz, Robert
Description: On April 2, 2007, the Supreme Court rendered one of its most important environmental decisions of all time. In Massachusetts v. EPA, 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. Environmental Protection Agency (EPA) had improperly denied a petition seeking CAA regulation of GHGs from new motor vehicles by saying the agency lacked authority over such emissions. This report presents a chronology of major federal agency actions, mainly by EPA, in the wake of Massachusetts v. EPA.
