HFC's, or hydrofluorocarbons, are used in air conditioners and refrigerators and have been hailed by environmental groups as the fastest growing climate pollutant in the world. On Saturday, several environmental groups reported that nations, including the United States of America, agreed to the deal after the 28th Meeting of the Parties to the Montreal Protocol on Substances that Deplete the Ozone Layer in Kigali, Rwanda.United States of America Secretary of State, John Kerry, delivered a speech at the conference on Friday.
The United States of America is the second worst country in the world in terms of pollution. They are second toChina, the top global carbon emitter. The United States will begin capping its use of HFC's in 2019. China will follow suit in 2024. Over 100 nations, including India, Pakistan and severalMiddle Eastern nations, will begin their part of the deal by2028. India, which is the third worst polluting country in the world, had previously pushed to begin capping its use of HFC's in 2031.
Environmental scientists have calculated that such an agreement, which will be officially announced at a later date, will likely put a half degree Celsius dent in the warming of the globe by the 22nd Century.
"Compromises had to be made, but 85 percent of developing countries have committed to the early schedule starting 2024, which is a very significant achievement," read a statement from UK Climate Campaign Leader with the Environmental Investigation Agency,Clare Perry.
