US&CHINA TO PHASE OUT CONSUMPTION, PRODUCTION OF HYDROFLUOROCARBONS

摘要

The United States and China, the world's top two greenhouse-gas emitters, have agreed to work together and with other countries to phase down the consumption and production of hydrofluorocarbons (HFC) as an important new step to combat global climate change. A global phase down of HFC could potentially reduce some 90 gigatonnes of CO2 equivalent by 2050, equal to roughly two years worth of current global greenhouse gas emissions, the White House statement said after the two-day informal summit.
