The United States and China have agreed to work to “phase down” HFCs. In a press release the White House announced:
” …the United States and China agreed to work together and with other countries through multilateral approaches that include using the expertise and institutions of the Montreal Protocol to phase down the production and consumption of HFCs…Every country in the world is a party to the Protocol, and it has successfully phased out or is in the process of phasing out several key classes of chemicals, including chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and halons. The transitions out of CFCs and HCFCs provide major ozone layer protection benefits, but the unintended consequence is the rapid current and projected future growth of climate-damaging HFCs.”
