"For too long...we have accepted a narrative that if you're pro-growth, pro-jobs, you're anti-environment; if you're pro-environment, you're anti-jobs or anti-growth", Pruitt said.
But it's been on hold since previous year.
The plan is being challenged in the US Circuit Court of Appeals for the District of Columbia. The president's top advisers have been divided over whether America should formally withdraw from the 2015 global warming pact that Obama and his deputies helped broker through the U.N. Framework Convention on Climate Change.
Trump has already alarmed environmentalists by ordering completion of the controversial Keystone oil pipeline, promising to revive the moribund USA coal industry, and asking the EPA to reconsider rules regulating clean water and fuel economy for cars. Supporters of the regulations argue in briefs that they will "secure critically important reductions" in carbon dioxide emissions from what are by far "the largest emitters in the United States - fossil-fuel-fired power plants". "Paris was just a bad deal, in my estimation".
But challengers say the rule exceeds the EPA's statutory authority and goes beyond the bounds set by the Constitution.
Told by ABC host George Stephanopolous that most coal-job losses took place a decade ago under Obama's predecessor George W. Bush - as natural gas increasingly replaced coal - Pruitt dismissed concerns that Trump had made a promise he can't keep.
Comey took revenge on Trump over wiretap claim
In March, Trump sparked controversy when he said he had evidence that Obama had wiretapped his campaign against Clinton.
The big question for many is how will the Trump orders impact the dying coal industry.
There are, however, limits to what the president can do by executive order. His Environmental Protection Agency is aiming to aggressively roll back Obama-era environmental regulations.
Trump campaigned on a platform that Obama-era environmental regulation had led to job losses, particularly in coalmining areas.
With the installation of a new EPA chief, Scott Priutt - a confirmed global warming skeptic - the electricity production sector of the economy is about to receive a much needed shot in the arm.
The "Energy Independence Executive Order" is created to relax regulations on power plants, while the Trump administration will also review fuel efficiency standards for cars.
