U.S. EPA completes rule to phase out gases used as refrigerants
CTV
In what officials call a key step to combat climate change, the U.S. Environmental Protection Agency is sharply limiting domestic production and use of hydrofluorocarbons, highly potent greenhouse gases commonly used in refrigerators and air conditioners.
The new rule, which follows through on a law Congress passed last year, is intended to decrease U.S. production and use of HFCs by 85% over the next 15 years, part of a global phaseout designed to slow global warming.
HFCs are greenhouse gases that are thousands of times more powerful than carbon dioxide. They often leak through pipes or appliances that use compressed refrigerants and are considered a major driver of global warming. U.S. President Joe Biden has pledged to embrace a 2016 global agreement to greatly reduce HFCs by 2036.
White House climate adviser Gina McCarthy, a former EPA administrator, said the new rule was "a win on climate and a win on jobs and American competitiveness."
The rule is expected to reduce harmful emissions by the equivalent of 4.5 billion metric tons of carbon dioxide by 2050, McCarthy said, a total similar to three years of emissions from the U.S. power sector.
