On Thursday, the US Supreme Court ruled 6-3 to restrict the Environmental Protection Agency's authority to regulate greenhouse gas emissions from power plants.
"Capping carbon dioxide emissions at a level that will force a nationwide transition away from the use of coal to generate electricity may be a sensible 'solution to the crisis of the day. But it is not plausible that Congress gave EPA the authority to adopt on its own such a regulatory scheme in Section 111(d). A decision of such magnitude and consequence rests with Congress itself, or an agency acting pursuant to a clear delegation from that representative body."
- John Roberts, Chief Justice of the United States
The ruling is a win for coal companies in their long-running campaign to limit the EPA's authority to enact policies aimed at reducing carbon emissions.
