Homonym: HFC (Hydrofluorocarbon)
HFC stands for hydrofluorocarbons, which are a group of man-made chemicals used primarily in refrigeration, air conditioning, and aerosol propellants. They are known for their ability to cool effectively and are often seen as alternatives to ozone-depleting substances like CFCs (chlorofluorocarbons). However, HFCs are potent greenhouse gases, contributing to climate change.
Due to their environmental impact, many countries are working to phase out HFCs under international agreements such as the Montreal Protocol. This treaty aims to reduce substances that harm the ozone layer and mitigate global warming, promoting the use of more sustainable alternatives in various industries.
