Concerns on whether proposed air pollution regulations in the U.S. are 'fatally flawed' have been dismissed by the organization who backs them.
"We are alive and well, and there is no fatal flaw," Gina McCarthy, administrator for the U.S. Environmental Protection Agency (EPA), told CNBC Tuesday.
"The Clean Air Act has been very good for 45 years in driving down 70 percent of the pollution we've emitted, while we've tripled our GDP (gross domestic product). It's because we do it right, we have the information, we show the cost benefits, we prove that you can keep improving the environment while you grow the economy."
"So the Clean Power Plan—which is really the keystone of President (Barack) Obama's plan—is not just alive and well, but we are doing incredibly well."
