Reuters reports the Trump administration is expected to roll back an Obama-era rule regulating coal plants.
The rules required new coal plants to slash carbon emissions.
The rollback, which is expected Thursday, could open the door in coming years for new plants fired by the fossil fuel.
The Environmental Protection Agency (EPA) will make an “energy policy announcement” at 1:30 p.m. on Thursday.
The Trump proposal would replace an Obama-era standard allowing only 1,400 pounds of carbon per megawatt-hour.
