Environmentalists praise Stevens, the author of landmark climate case

EPA has determined greenhouse gases like carbon dioxide do endanger human health and is writing a rule to reduce emissions. Some members of Congress want to stop EPA or delay its rulemaking. Environmental groups are fighting to preserve the power Stevens and the Court gave EPA, particularly given the trouble Congress is having coming up with their own climate plan.

Stevens is the court’s oldest member. He has served on the court for 34 years.
