Guide d'introduction aux HFC. Une action rapide dans le cadre du protocole de Montréal peut limiter la croissance des hydrofluorocarbures (HFC), empêcher 100 à 200 milliards de tonnes d'équivalent CO2 d'ici 2050, et éviter un réchauffement pouvant atteindre 0,5° C d'ici 2100.

Résumé

HFCs are the fastest growing greenhouse gases in much of the world, increasing at a rate of 10–15% per year. They are factory-made gases that were once necessary to replace ozone-depleting substances, but today are no longer needed in most sectors, including air conditioning, refrigeration, and foam insulation. At least 95 countries have indicated their support for proposals to amend the Montreal Protocol to phase down HFCs. A fast phasedown of HFCs under the Montreal Protocol by 2020 would prevent 100 to 200 billion tonnes (Gt) of CO2-equivalent (CO2-eq) emissions by 2050, and avoid up to 0.5°C warming by 2100,using a treaty that requires developed countries to act first, provides implementation assistance to developing countries, and has the experience and expertise to ensure that reductions are fast, effective, and efficient. The Kigali Amendment to phase down HFCs under the Montreal Protocol will provide a level playing field for producers and consumers in lieu of a growing patchwork of regional and national regulations. Meanwhile, governments and leading companies in the E.U., Japan, U.S., and elsewhere are already taking action to phasedown HFCs. First published in 2013, IGSD’s HFC Primer was created to consolidate and track available and relevant scientific, technological, and policy knowledge on the issue of HFCs as well as the progress towards a phasedown under the Montreal Protocol. With the passage of the Kigali Amendment to phasedown HFCs in October 2016, the HFC Primer now serves as a record of this nearly decade-long process and details the actions of states, industry, and international community as they worked to create and adopt the Kigali Amendment.
