WebAre chlorofluorocarbons responsible for global warming? Along with destroying the Ozone layer, chlorofluorocarbons trap heat in the lower levels of the atmosphere. This leads to … WebOzone layer depletion is a major concern and is associated with a number of factors. The main causes responsible for the depletion of the ozone layer are listed below: Chlorofluorocarbons. Chlorofluorocarbons or CFCs are the main cause of ozone layer depletion. These are released by solvents, spray aerosols, refrigerators, air-conditioners, …
WebCFCs, on the other hand, are so stable and unreactive that they survive reaching the highest levels of the atmosphere and becoming globally distributed in the stratosphere. The most common ozone-depleting substance is chlorofluorocarbons. The chlorine atom does not react with ozone unless it reacts with another molecule.

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.
