UN report projects that increasing use of HFCs likely to have a significant climate impact by 2050; equivalent to current total annual emissions from transport

Green Car Congress

The decrease in CO 2 equivalent emissions of ODSs (ozone-depleting substances: CFCs, halons, HCFCs, and others) may be offset by the projected increase in their non-ozone depleting substitutes (HFCs) (lines designated as HFC scenarios). The contribution of HFCs to climate forcing is currently less than 1% of all greenhouse gases.

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

Green Car Congress

The US reached separate agreements with the G-20 and with China to address the rapid growth in the use and release of climate-damaging hydrofluorocarbons (HFCs). Left unabated, HFC emissions could grow to nearly 20% of carbon dioxide emissions by 2050, a serious climate mitigation concern.
