US, China, and G-20 agree to work to global phase down of HFCs

Green Car Congress

While they do not deplete the ozone layer, many are highly potent greenhouse gases whose use is growing rapidly as replacements for ozone-depleting substances being phased out under the Montreal Protocol. Left unabated, HFC emissions could grow to nearly 20% of carbon dioxide emissions by 2050, a serious climate mitigation concern.
