The U.S. Court of Appeals for the District of Columbia Circuit heard 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 were EPA’s response to Massachusetts v. EPA and represented the bedrock of EPA’s regulation of greenhouse gas emissions under the Clean Air Act (CAA).
The court’s rulings on these four rules had the potential to halt, delay, modify, or greatly increase the scope of greenhouse gas regulation under the CAA. The stakes were among the highest in recent environmental litigation.
Our distinguished panelists, many of whom participated in the arguments, described and dissected the previous days’ oral arguments and discussed the implications of the potential outcomes.
