Hydrofluorocarbons (HFCs) are potent greenhouse gases used as alternatives to ozone-depleting substances (ODS) being phased out under the Montreal Protocol. Atmospheric observations show that the volume of HFCs in the atmosphere is increasing rapidly, about 10-15% per year.
Significant growth in HFC use is expected in developing countries because of population growth, rapid urbanization, electrification and changing consumer patterns. The increased use of refrigerants will also result in increased energy consumption and greenhouse gas emissions. If no measures are taken, it is estimated that HFCs will amount to 9-19% of total CO2 emissions by 2050.
Since its creation in February 2012, the Climate and Clean Air Coalition to reduce short-lived climate pollutants (CCAC) actively worked with partners to promote HFC phasedown under the Montreal Protocol. In October 2016, the Kigali Amendment to the Montreal Protocol was adopted and Coalition continues to support the successful implementation of the Kigali Amendment by actively encouraging all its partner countries to ratify the Amendment.
Awareness-raising and capacity building remain necessary for sharing information and building the confidence of governments, the industry and other stakeholders that alternatives to HFCs are available.
