President Trump's environmental chief announced Monday he'll undo former President Obama's initiative to reduce emissions by power plants.
"As EPA administrator, Scott is working to strike an appropriate balance between protecting water and air, and preventing the kind of job-killing over-regulation", McConnell said, adding that he's been working to "stop the war on coal in its tracks".
Pruitt's attempt is the latest in the Trump Administration's risky campaign of climate change denial, and is a wake-up call for state and local leaders: if you want to protect your citizens, it's time to take action yourselves because the Trump-Pruitt EPA has shown it's more interested in protecting polluters than the health of Americans.
After months of Donald Trump disparaging Obama's climate efforts, this document makes the Clean Power Plan's demise official.
Environmental groups were sharp in their denunciation of Pruitt's announcement.
However, the Clean Power Plan has essentially been on hold since February 2016, when the US Supreme Court halted its implementation until courts could decide whether it was legally valid.
One of the many lawsuits Pruitt filed against the EPA while Oklahoma's attorney general was specifically in opposition to the Clean Power Plan.
Trump has voiced doubts about the science of climate change and has blamed Obama's efforts to reduce carbon emissions for hurting the coal mining and oil drilling industries.
But trade organizations like the National Association of Manufacturers, which participated in a legal challenge to the plan, praised it.
As Oklahoma's attorney general, he took part in a lawsuit by 27 U.S. states against the rule.
Even so, the plan has been a factor in a wave of retirements of coal-fired plants, which also are being squeezed by lower costs for natural gas and renewable power and state mandates promoting energy conservation.
The EPA has not decided whether it will replace the Clean Power Plan, according to a draft of the proposal seen by Reuters on Friday, or whether or when it will propose a new rule to regulate emissions from existing power plants. A plant-specific approach "would be grossly insufficient to address the public health and environmental impacts from Carbon dioxide emissions", Obama's EPA said.
