Benefits of Addressing HFCs Under the Montreal Protocol

Although safe for the ozone layer, continued emissions of hydrofluorocarbons (HFCs) – primarily as alternatives to ozone-depleting substances (ODS) but also from ongoing production of Hydrochlorofluorocarbon (HCFC)-22 – will have an immediate and significant effect on the Earth’s climate system. Without controls, it is predicted that HFC emissions could negate the entire climate benefits achieved under the Montreal Protocol. HFCs are rapidly increasing in the atmosphere. HFC use is forecast to grow, mostly due to rising demand for refrigeration and air conditioning, particularly in developing countries (Article 5 countries, in the parlance of the Montreal Protocol). There is a clear connection to the Montreal Protocol’s chlorofluorocarbon (CFC) and HCFC phaseout and the increased use of HFCs. However, there remains an important opportunity – one the world community may yet seize – to preserve and even build upon the significant climate benefits achieved by the Montreal Protocol by using climate-friendly alternatives and addressing HFC consumption. Recognizing the environmental downsides of continued HFC consumption and emissions, the need for continued HFC use in the near future for certain applications, and the longer term requirement for better alternatives across the board, Canada, Mexico and the United States have proposed an amendment to phase down HFC consumption and to reduce byproduct emissions of HFC-23, the HFC with the highest GWP, arising from production of HCFC-22. The proposed Amendment would build on the success of the Montreal Protocol, rely on the strength of its institutions, and realize climate benefits in both the near and long-term.
