A random courthouse photographed from a dramatic angle.

This morning, a federal appeals court in Washington, D.C., upheld the Environmental Protection Agency’s (EPA) first-of-its-kind greenhouse gas regulations, dismissing out of hand a variety of challenges from industry and states. The findings uphold the agency’s rules defining limits to the emission of greenhouse gas pollution under the Clean Air Act. Specifically, the court ruled: Yes, the agency acted properly in determining that CO2 is a danger to public health; yes, it was right to use that determination to regulate vehicles; and yes, it was within its authority to determine the timing (Timing Rule) and scope (Tailoring Rule) of the regulations.

The Wall Street Journal called the decisions “a blow to an array of industry groups”; Politico declared them “a surprisingly sweeping win.” In short: very good news.
