WebJun 8, 2024 · CFCs are halocarbons that contain only the elements carbon, chlorine, and fluorine. The most common CFCs are small molecules containing only one or two carbon atoms. For example, a common refrigerant has the chemical formula of CCl2F2, which in an industry-devised shorthand is noted as CFC-12. WebClO + O = Cl + O2. The industrial production of CFCs started in the 1920’s, causing an average reduction of the ozone layer of 3 per cent. Fortunately, chlorine has “natural enemies” as well, such as methane (CH4). Thanks to them, the natural ozone layer could recover over 50 years, as long as CFCs are no longer used on a global level. dataethics winter school 2022 https://sigmaadvisorsllc.com
