Hydrochlorofluorocarbons (HCFC) are liquids or gases that are most commonly used in refrigeration and air conditioning. Break it down and it’s a compound made of hydrogen, chlorine, fluorine, and carbon. They were developed for and are used as a less ozone-depleting substance (ODS) than chlorofluorocarbons (CFCs). You’ve probably heard of CFCs, the ODS that were phased out years ago. HCFCs are considered Class II ODS, which means they have less potential to destroy the ozone layer than Class I ODS, such as CFCs. HCFCs are being incrementally phased out, leading to a complete HCFC phase out by 2030.

HCFCs are a problem when they leak into the atmosphere during manufacturing, use, or disposal. They are a very powerful greenhouse gas, which contribute to climate change. Continue reading
