The new Environmental Protection Agency rule targets hydrofluorocarbons, greenhouse gases that are thousands of times more powerful than carbon dioxide.
The Environmental Protection Agency proposed a rule Monday to slash the use and production of a class of powerful greenhouse gases used widely in refrigeration and air conditioning in the next decade and a half. The proposal marks the first time President Biden’s administration has used the power of the federal government to mandate a cut in climate pollution.
Unlike many of the administration’s other climate initiatives, there’s broad bipartisan support for curbing hydrofluorocarbons, pollutants thousands of times more potent than carbon dioxide at warming the planet. Congress agreed at the end of last year to slash the super-pollutants by 85 percent by 2036 as part of a broader omnibus bill.
A global phasedown of hydrofluorocarbons, also known as HFCs, is projected to avert up to 0.5 degree Celsius (0.9 degrees Fahrenheit) of warming by the end of the century.
Widely used in refrigeration, as well as residential and commercial air conditioning and heat pumps, HFCs were developed as a substitute for chemicals that depleted the Earth’s protective ozone layer. But their heat-trapping properties have helped increase temperatures.
