"The Environmental Protection Agency (EPA) Tuesday took another step toward reducing the use of planet-warming gasses called hydrofluorocarbons, issuing a rule moving toward a 40 percent phasedown of the substances.

Hydrofluorocarbons, also known as HFCs, are used in refrigeration and air conditioning. They can be hundreds or even thousands of times more potent than carbon dioxide as a greenhouse gas.

The EPA is required to make companies gradually reduce their consumption of the substances over time as part of a law that was passed in 2020 under a bipartisan energy compromise."
