In a blow towards efforts to reduce global warming, the administration of US President Donald Trump reportedly announced on October 9 that it would take formal steps to repeal former US president Barack Obama’s key policy to reduce greenhouse gas emissions from power plants. Trump had made a pre-election promise to eradicate his Obama’s environmental legacy.

Environmental Protection Agency (EPA) head Scott Pruitt said in Kentucky his predecessors had departed from regulatory norms in crafting the Clean Power Plan, which was finalised in 2015 and would have pushed states to move away from coal in favor of sources of electricity that produce fewer carbon emissions, the NYT reported.

“The war on coal is over,” the newspaper quoted Pruitt as saying. “Tomorrow in Washington, D.C., I will be signing a proposed rule to roll back the Clean Power Plan. No better place to make that announcement than Hazard, Ky,” he added.

Trump has also vowed to abandon the Paris climate agreement to ratchet down emissions that are warming the planet.
