EPA to Adopt New Rules to Cut Emissions From Coolants
WASHINGTON—The Environmental Protection Agency is completing new rules to reduce the use of coolants in air conditioners and refrigerators that are potent greenhouse gases.
The rules create a process for reducing the use of hydrofluorocarbons in cooling appliances, the first step toward meeting new mandates to cut their supply by 85% over 15 years, the EPA said. Congress passed with bipartisan support that mandate in December in provisions included in a $2 trillion spending and Covid-19 aid package.
The EPA formally proposed the rules required under the law in May. Thursday’s moves complete that process to make the rules final.
The rules would cut the equivalent of 4.5 billion metric tons of carbon dioxide emissions from 2022 through 2050, or almost three years of U.S. power-sector emissions at 2019 levels, the EPA said. That is down slightly from the May proposal, which estimated a reduction of 4.7 billion metric tons.
