"U.S. companies brace for climate-friendly alternatives in cooling systems", 16 October 2016

U.S. chemical companies including Honeywell and Chemours Co are ramping up efforts to produce alternative coolants used in air-conditioners and refrigerators, following a global pact to reduce planet-warming greenhouse gas emissions…[S]ome 150 nations struck a global agreement…on ways to phase down hydrofluorocarbon (HFC) gases, which are currently used in air-cooling systems and refrigerators, and help curb the release of climate-warming emissions. The accord is an amendment to the 1987 Montreal Protocol, which was aimed at stopping the depletion of the ozone layer. As part of a larger goal to globally reduce HFCs by 80 percent by 2047, signatories such as U.S., India and China have agreed to phase out the pollutants from cooling appliances starting 2019. The agreement is a boon for chemical and equipment makers…and will help speed up development and testing of HFC alternatives…The Morris Plains…has already begun producing HFC substitutes used for foam insulation, aerosols, commercial refrigerants, and chiller applications...
