High gwp gases
WebChlorodifluoromethane or difluoromonochloromethane is a hydrochlorofluorocarbon (HCFC). This colorless gas is better known as HCFC-22, or R-22, or CHClF 2.It was commonly used as a propellant and refrigerant.These applications were phased out under the Montreal Protocol in developed countries in 2024 due to the compound's ozone … WebHCFCs are both ODS and powerful greenhouse gases: the most commonly used HCFC is nearly 2,000 times more potent than carbon dioxide in terms of its global warming potential (GWP). Recognizing the potential benefits to the Earth’s climate, in September 2007 the Parties decided to accelerate their schedule to phase out HCFCs.
