ALI-ABA Roundtable on the Supreme Court's Climate Change Decision in Massachusetts v. EPA

May 18, 2007

On April 2, 2007, the US Supreme Court ruled, by a 5-4 vote, that the EPA's decision to reject a petition to regulate greenhouse gases from new motor vehicles was invalid. In so doing, the Court held that petitioners had established injury from climate change sufficient to support standing to sue; that greenhouse gases are "air pollutants" as defined under the Clean Air Act; and that EPA could not decline to regulate on various policy considerations independent of the danger posed by climate change. 

This roundtable brings together the leading thinkers and decisionmakers to discuss the implications of each of the three issues the Court decided. 

Jonathan Martel is the planning chair for this teleseminar.
