含氟烯烃:制冷剂、发泡剂的下一个全球主流产品以氢氟碳化物(HFC)为代表的第三代制冷剂、发泡剂,虽然对臭氧层没有破坏作用[即臭氧消耗潜能值(ODP)为零],但含有较高的全球变暖潜能值(GWP),被《京都议定书》列为温室气体。中美两国于2016年G20峰会上达成削减HFC的共识。2016年10月15日,《蒙特利尔议定书》第28次缔约方大会聚焦HFC减排,各国达成HFC削减时间协议。
Fluorinated olefins: Refrigerants, blowing agents, the next global mainstream HFC hydrofluorocarbons (HFCs) represented the third generation of refrigerants, blowing agents, although not damaging to the ozone layer [that is, the ozone depletion potential ODP) is zero], but contains a higher GWP and is classified as a greenhouse gas by the Kyoto Protocol. China and the United States reached a consensus to cut HFC at the 2016 G20 summit. On October 15, 2016, the 28th Meeting of the Parties to the Montreal Protocol focused on HFC emission reductions and reached an agreement on the HFC cut-off time.
