"Next Generation" Refrigerants to Reduce Global Warming Potential

DuPont led the transition away from chlorofluorocarbon (CFC) refrigerants by introducing, non-ozone-depleting hydrofluorocarbons (HFCs) in 1991.  The company maintains that HFCs currently represent the best balance of performance, cost, safety and environmental properties for refrigeration and air conditioning.  DuPont actively supports HFC responsible use programs to ensure current refrigerants are used safely and responsibly and are reclaimed and recycled to minimize potential sources of emissions. 

DuPont is developing new refrigerant compounds  as part of its ongoing program to seek longer term sustainable alternative solutions for refrigerants that have high global warming potential (GWP), and are used widely in automotive air conditioning, home refrigerators, supermarkets and store display cases and in building and home air conditioning systems. DuPont Fluorochemicals has identified and is now testing new proprietary refrigerants to reduce their global warming potential (GWP) in future automotive air conditioning systems. The new refrigerants for automotive air conditioning systems are expected to be commercialized within three to five years, in time to meet the timeline set by the pending European Union F-Gas regulation.
