Clean Power Plan

United States government policy

Quick Summary

The Clean Power Plan was a United States government policy proposed by the Environmental Protection Agency (EPA) in 2015. It aimed to regulate greenhouse gas emissions from power plants, specifically targeting carbon dioxide. The plan sought to set output-based standards, requiring new fossil-fuel power plants to emit no more than 1,000 pounds of CO2 per megawatt-hour. This standard was already met by most new natural gas plants built after 2005, but would have significantly impacted new coal plants, which emitted much higher levels of CO2.1

The policy was part of broader efforts to address climate change and was rooted in the EPA's authority under the Clean Air Act. However, the U.S. Supreme Court later limited the EPA's authority to impose such broad emissions caps without explicit congressional authorization.2
