(AP Photo/Carolyn Kaster) WASHINGTON (CN) — The Environmental Protection Agency on Monday announced the nation’s first-ever limits on a super-pollutant that is thousands of times more potent at heating up the planet as compared with carbon dioxide. The new regulation creates a process to phase down hydrofluorocarbons (HFCs), coolants primarily used in refrigeration and air conditioning systems, by 85% over the next 15 years — part of the Biden administration’s strategy to half the country’s greenhouse gas emissions by 2030. “EPA is taking a major action to help keep global temperature rise in check,” the agency’s head, Michel S. Regan, said in a statement. “The phasedown of HFCs is also widely supported by the business community, as it will help promote American leadership in innovation and manufacturing of new climate-safe products. Put simply, this action is good for our planet and our economy.”
