The D.C. Circuit's Rulings on EPA's Greenhouse Gas Rulemakings


June 27, 2012



In February 2012, the U.S. Court of Appeals for the District of Columbia Circuit held two days of oral argument to review four of EPA’s greenhouse gas emissions rules: The "Timing" Rule, The "Tailoring" Rule, The "Endangerment" Rule, and The "Tailpipe" Rule.

These four rules are EPA’s response to Massachusetts v. EPA and represent the bedrock of EPA’s regulation of greenhouse gas emissions under the Clean Air Act (CAA). When the court ruled on those hearings, a panel was convened to discuss the rulings and their potential effects on industry, the environment, and the future of federal greenhouse gas regulation.
