HFCS: realising the potential for climate benefits from the Montreal Protocol
IIn 1987, the Montreal Protocol phased out the use of chlorofluorocarbons (CFCs), an ozone-depleting substance (ODS) used as coolants in refrigeration and air conditioning. Unfortunately, the chemicals increasingly being deployed in their place, hydrofluorocarbons (HFCs) are themselves exceptionally potent greenhouse gases. They are often called super greenhouse gases because their global warming potential (GWP) is more than carbon dioxide by a factor of 1000.
