18 states file suit to compel EPA to act on climate change.

A year ago today, the U.S. Supreme Court in Massachusetts et al. v. Environmental Protection Agency et al. ruled that carbon dioxide from fossil fuels is a pollutant subject to the Clean Air Act, and directed the EPA to determine whether such emissions, associated with climate change, endangered public health. Today, according to mainstream news sources, 18 states have sued the EPA to act within 60 days. It’s a mandamus-like pattern states, cities and public interest groups have used for two decades under the CAA to prompt the EPA to move on other issues within its expertise, such as interstate acid rain transport.
