The U.S. Environmental Protection Agency reportedly plans to repeal coal- and gas-power-plant carbon-emissions limits; final action remains pending.

Reports say the U.S. Environmental Protection Agency (EPA) was preparing to repeal carbon-pollution standards for fossil-fuel power plants. Unnamed sources said an announcement could occur as early as Monday during the Group of Twenty energy ministers’ meeting in Houston; the supplied material does not contain a final rule.

The reported action concerns Biden-era requirements for existing and future fossil-fuel power plants to substantially reduce greenhouse-gas emissions over coming decades. The source identifies carbon capture and storage among the technologies contemplated by those requirements.

According to the detailed report, the EPA first proposed withdrawing the power-plant climate regulations in the preceding summer and was preparing to finalize part of that proposal. Officials also planned a separate rule to withdraw the finding that power-plant greenhouse-gas emissions independently constitute a threat under the Clean Air Act.

The report places this action after the agency’s reported withdrawal earlier in the year of analogous vehicle standards and the 2009 greenhouse-gas endangerment finding. It provides no quantified change in generating capacity, electricity prices, or data-center power availability.
