Résumé

In the absence of an HFC phase-down amendment, HFC growth would continue with more than 80 percent of use of HFCs in Article 5 Parties3 in 2050. Alternatives to high-GWP HFCs have been developed and are being used in all major use sectors. National regulations in Australia, Canada, European Union, Japan and the United States have and will continue to drive the expanded use of low-GWP HFC alternatives in the near and long term. In most sectors a range of options exists including next-generation fluorocarbon (hydrofluoroolefins—HFOs), lower-GWP HFCs, hydrocarbons (HCs) and other non-fluorocarbon refrigerants and foam blowing agents.In past transitions, NIK alternatives including substitutes other than fluorocarbons (e.g., HCs, carbon dioxide), recycling and recovery, and emission reductions have reduced reliance on ozone-depleting substances (ODSs) by as much as 85 percent.Based on the current availability of non-fluorinated alternatives and likely emission reductions, the overall opportunity for NIK alternatives to substitute for HFCs is expected to be on the order of 50 percent.NIK alternatives to replace high-GWP HFCs also have the potential to significantly decrease energy use in the refrigeration and air conditioning sectors.By providing a broader range of alternatives and emission reductions, NIKs provide market and price competition to next-generation HFO substitutes which are restricted by patents for a specified period of time. Efforts are underway, but will require several more years to fully address changes in codes and standards to ensure a wider range of more flammable alternatives can be used safely.
