The Environmental Protection Agency is enforcing stricter limits on hydrofluorocarbons, highly potent greenhouse gases used in refrigerators and air conditioners that contribute to global warming.
A rule announced Tuesday will impose a 40% overall reduction in HFCs starting next year, part of a global phaseout designed to slow climate change. The rule aligns with a 2020 law that calls for an 85% reduction in production and use of the climate-damaging chemicals by 2036.
