Biden administration takes aim at climate warming gas

Washington: The US Environmental Protection Agency on Thursday finalized a rule that will slash the use of a potent climate-warming gas commonly used in refrigerators and air conditioners by 85% over the next 15 years, a move that will help halve greenhouse gas emissions this decade.

The rule aims to phase out the use of hydrofluorocarbons (HFCs) by 85% in a range of common appliances and carries out legislation passed with bipartisan support in Congress last year. It would make the U.S. compliant with the Kigali amendment to the Montreal Protocol, a global treaty to reduce HFCs that the U.S. has not yet ratified.

"It really sends a signal to the rest of the world that we are all in on climate change," National Climate Advisor Gina McCarthy told reporters on Tuesday evening.
