"CSE presents its blueprint for resolving the issue of HFCs at the Montreal Protocol in Paris"
Hydrofluorocarbons (HFCs) are powerful greenhouse gases used primarily as refrigerants, in foams, solvents and some medical applications. They are currently being phased in as a replacement gas for substances controlled under the Montreal Protocol. The Montreal Protocol is an international treaty set up to address the ozone hole and contains the consumption and production of ozone-depleting substances. Although HFCs are not ozone-depleting substances, a phase-down of HFCs under the Montreal Protocol presents a significant climate co-benefit. The ongoing session of the 34th Open-ended working group (OEWG) under the Montreal Protocol in Paris is discussing a potential phase-down of HFCs, the hidden opportunities and the barriers to ensuring that the significant growth of HFCs are arrested.
