Later this summer, the Environmental Protection Agency (EPA) plans to unveil a Clean Power Plan for state-by-state cuts in carbon emissions. Some utilities have already challenged the authority of the EPA to regulate greenhouse gases under a provision of the Clean Air Act. This week’s U.S. Supreme Court ruling requiring the EPA to rewrite its mercury emissions regulations could changing the legal grounds for further challenges to the Clean Power Plan.

We talk to Melissa Powers, associate law professor at Lewis & Clark Law School, about the ruling and its potential consequences.
