Massachusetts v. EPA - A Missing Opportunity to Bring Clarity and Principle to the Clean Air Act

The case was about the scope of EPA's power to regulate greenhouse gas emissions from power plants. There was a debate over whether greenhouse gas emissions should be considered pollutants under the Clean Air Act. The court has recognized that while greenhouse gases are pollutants, that does not give the EPA the authority to alter the act or its operation so as to make it operate better for them.
