California Bans Climate-Warming HFCs in New Air-Conditioning and Refrigeration

The California Air Resources Board has banned the use of hydrofluorocarbons (HFCs) in new cooling equipment. The climate-warming chemicals are between 1,000 and 3,000 times more potent than carbon dioxide. The decision follows a federal court ruling last year that found the EPA did not have the authority to regulate HFCs.
