Environmental Protection Agency chief Gina McCarthy said natural-gas production — with the right safeguards — is a major piece of Obama administration efforts to combat global warming.

“Responsible development of natural gas is an important part of our work to curb climate change and support a robust clean energy market at home,” she said Wednesday at a speech in Colorado, according to prepared remarks.

The comments are part of a wider administration effort to cast the U.S. gas production boom as a way to help slow global warming.

They come two weeks after Energy Secretary Ernest Moniz rejected claims that natural gas isn’t helping in the fight against warming due to releases of the potent greenhouse gas methane at wells, transport and processing sites.
