Environmental Protection Agency Administrator Gina McCarthy admitted her agency’s signature regulation aimed at tackling global warming was meant to show “leadership” rather than actually curb projected warming.

McCarthy admitted as much after being questioned by Kentucky Republican Rep. David McKinley, who pressed the EPA chief on why the Obama administration was moving forward with economically-damaging regulations that do nothing for the environment.

“I don’t understand,” McKinley said in a Tuesday hearing. “If it doesn’t have an impact on climate change around the world, why are we subjecting our hard working taxpayers and men and women in the coal fields to something that has no benefit?”

“We see it as having had enormous benefit in showing sort of domestic leadership as well as garnering support around the country for the agreement we reached in Paris,” McCarthy responded.

McKinley was referring to EPA’s so-called Clean Power Plan, which forces states to cut carbon dioxide emissions from coal-fired power plants. The CPP is expected to double the amount of coal plant closings in the coming years, and even EPA admits it won’t have a measurable impact on projected global warming.

EPA has long argued the point of the CPP was to show the world America was serious about tackling global warming in order to galvanize support for United Nations delegates to sign a global agreement to cut emissions. Nearly 200 countries agreed to a U.N. deal last year.

“But even then no one is following us,” McKinley said. “Since that Paris accord China has already announced that they’re going to put up 360 [coal plants]. India has announced that they’re going to double their use of coal since the Paris accord.”

China has made promises to curb its coal use in order to tackle the country’s horrible air pollution problems, but China still plans on using more coal in the future. Likewise, India promised in December to double its coal production by 2020.

EPA, however, has bigger problems than global concern over warming. The Supreme Court forced the agency to stop implementing its rule in February, siding with a coalition of 29 states and state agencies suing to have the CPP thrown out.
