EPA Bans Certain Uses of HFCs in Push To Limit Potent Climate Change Contributors

摘要

The Environmental Protection Agency will phase out use of some hydrofluorocarbons in favor of substances with less climate impact as part of the latest effort in President Barack Obama's plan to reduce greenhouse gas emissions. The final rule, signed by EPA Administrator Gina McCarthy July 2 and issued under Section 612 of the Clean Air Act, would list as unacceptable certain hydrofluorocarbons (HFCs) previously permitted for use by chemical and equipment manufacturers in aerosols, foam blowing, motor vehicle air conditioning, retail food refrigeration and vending machines. The EPA concluded other chemicals are available for the same uses but pose less risk to human health and the environment, according to the final rule.
