Ashley Strickland, CNN, 21 Aug. 2021 Freon is a chlorofluorocarbon (CFC), which depletes the ozone layer and also acts as a global warming gas. Eric Dean Wilson, Time, 30 June 2021 Freezers and refrigerators have housed some of the most potent greenhouse gases, including the compound known as R12, a chlorofluorocarbon with roughly 10,000 times the destructive potential of CO2. Lindsey Mcginnis, The Christian Science Monitor, 11 May 2021 Solar geoengineering with aerosols runs head into the fact that aerosols, like ozone layer-destroying chlorofluorocarbon (CFC) spray aerosols, have often been a contributor to climate change. Caroline Delbert, Popular Mechanics, 26 Mar. 2021 These include chlorofluorocarbons, which are found in air conditioners, refrigerators, and spray cans, halons, which are found in fire extinguishers, and methyl bromide, which is used to kill weeds, insects, and other pests.
