EPA Grants Petitions to Stem Climate Pollutants in Future Rules

Oct. 8, 2021, 4:19 PM

The EPA will begin crafting rules to transition certain sectors way from using hydrofluorocarbons, a move authorized by legislation to phasedown the use of the potent greenhouse gas.

The Environmental Protection Agency granted ten petitions to cut the use of the chemicals, also called HFCs, in the refrigeration and air conditioning, aerosols, and foam sectors, according to a Friday announcement. The move supplements regulations finalized last month.

“Today’s actions are another step forward in advancing President Biden’s commitment to tackle the climate crisis, as we work to phase down and restrict the use of super-polluting HFCs as Congress directed,” EPA Administrator Michael Regan said in a statement.

The petitions were filed as part of a broader mandate from Congress—the American Innovation and Manufacturing Act—to slash the use of HFCs, which are largely found in industrial refrigeration and air conditioning.

After granting the petitions, the EPA now has two years to craft rules to limit the use of HFCs in the specified areas, including residential air conditioners, dehumidifiers, and aerosol propellants.

The Natural Resources Defense Council, DuPont, and the Air-Conditioning, Heating, and Refrigeration Institute were among the mix of industry and environmental petitioners.

“Replacing dangerous HFCs in key products will bring us a smooth and rapid transition to climate-friendlier air conditioners, refrigerators, aerosols, insulation, and other products Americans use every day, saving money and energy for consumers, creating new jobs, and protecting our climate and our health,” NRDC climate and clean energy policy advocate Christina Theodoridi said in a statement.
