US environmental regulators say power plant emissions do not significantly harm air quality

The US environmental regulators propose to repeal all rules limiting greenhouse gas emissions from fossil fuel power plants. This means power plants will no longer face federal requirements to reduce their carbon emissions.

For years, the US environmental regulators have used the Clean Air Act to limit pollution from power plants. This proposal removes carbon dioxide from the list of pollutants the agency considers dangerous enough to regulate under that law. It effectively ends federal efforts to force power plants to reduce their carbon footprint.
