Hydrofluorocarbons are highly potent greenhouse gases used in refrigerators and air conditioners.
Monday, the EPA announced to stop using climate superpollutants in products where more climate-friendly alternatives are available. According to E&E News, the agency granted or partially granted 11 petitions asking it to set rules for specific uses — refrigeration and air conditioning, aerosols, and foam sectors — mandating that manufacturers transition from using HFCs with high global warming potential to alternative chemicals that have less impact on the climate. Two additional petitions are still under review. The agency now has two years to complete rulemakings for the products and uses named in the accepted petitions under authorities granted to EPA by Congress last year.
