"The Biden administration on Thursday finalized its first major regulation to directly limit greenhouse gases, part of an effort to show America’s progress on global warming before a crucial climate summit in Glasgow in November.
The measure would curb the production and use of potent planet-warming chemicals called hydrofluorocarbons, or HFCs, which are used in air-conditioners and refrigerators. Without the new regulation, President Biden would be in danger of arriving at the United Nations summit in Glasgow with few concrete emissions-reducing measures to back up his calls for global action against climate change.
Mr. Biden has vowed to cut United States emissions 50 percent to 52 percent below 2005 levels in the next decade. But legislation that includes policies to cut carbon dioxide emissions from fossil fuels, the most prevalent greenhouse gas and the most politically difficult to address, faces uncertain prospects in a sharply divided Congress."
