Emissions of hydrofluorocarbons, heat-trapping industrial gases used in air conditioners and refrigerators, must be curbed to help combat climate change, according to the United Nations.
The UN report today comes as governments adhering to the ozone-protection rules of the Montreal Protocol consider phasing out hydrofluorocarbon-23 production, whose warming potential per molecule of HFC is 11,700 times more powerful than carbon dioxide. The European Union this year banned as of 2013 its use in the emissions-trading program of credits linked to the industrial gas generated under the UN carbon market.
