Definition of chlorofluorocarbon in US English:



  • fuller form of CFC
    • ‘The release of chlorofluorocarbons has led to the chemical reaction breaking down the ozone layer.’
    • ‘The hole isn't shrinking yet, but our use of aerosols and other chlorofluorocarbons is.’
    • ‘The concentration of CFCs in the atmosphere has increased almost exponentially since the 1930s but different chlorofluorocarbons have been released at known different rates.’
    • ‘If they contain only fluorine, chlorine and carbon they are called chlorofluorocarbons, or CFCs for short.’
    • ‘Since excess chlorofluorocarbons have been released into the atmosphere, the protecting stratospheric ozone layer has decreased and humans and animals are exposed to increased ultraviolet radiation.’
    • ‘When certain gases - carbon dioxide, water vapor, methane, chlorofluorocarbons, and others - are released into the atmosphere, they naturally act like the glass panes of a greenhouse.’
    • ‘Ozone loss in Earth's stratosphere is caused primarily by chemical reactions with chlorine from human-produced compounds like chlorofluorocarbons.’
    • ‘The protocol restricts the manufacture and use of human-made, ozone-depleting compounds, such as chlorofluorocarbons and halons.’
    • ‘The Caltech scientists suggest certain scenarios in which the impact could be similar to what chlorofluorocarbons inflicted on the ozone layer.’
    • ‘During the 1980s evidence emerged linking the release of chlorofluorocarbons, halons, and other chlorine-based substances with the gradual destruction of the ozone layer.’
    • ‘An example of this process is the formation of free radicals from chlorofluorocarbons in the upper atmosphere (leading to the depletion of the ozone layer).’
    • ‘Once the spring returns, this chlorine, much of it originating from man-made pollutants like chlorofluorocarbons, disrupts the ozone layer.’
    • ‘Stratospheric ozone over polar regions is subjected to enhanced seasonal depletion caused by emission of chlorofluorocarbons and other halogenated compounds.’
    • ‘Their research teams subsequently carried out experiments in the atmosphere that supported their hypothesis, leading to a worldwide effort to reduce the release of chlorofluorocarbons into the atmosphere.’
    • ‘In the last half of the twentieth century, the manufacture of chlorofluorocarbons for use as propellants in aerosol sprays and refrigerants has resulted in a slow mixing of these compounds with the stratosphere.’
    • ‘Up until the 1980s, a lot of liquefied-gas aerosol cans used chlorofluorocarbons as a propellant.’
    • ‘Refrigerator models made before 1994 may be insulated with chlorofluorocarbons, which also damage the earth's atmosphere.’
    • ‘The EU directive concerns the disposal of chlorofluorocarbons, CFCs, which damage the ozone layer if released into the atmosphere.’
    • ‘And today we will add 2,700 tons of chlorofluorocarbons to the atmosphere and 15 million tons of carbon.’
    • ‘A brief reference to the destruction of the ozone layer by chlorofluorocarbons, which has greatly enhanced the risk of skin cancer through increased ultraviolet radiation, appears in the summary of that section.’


1940s: from chloro- + fluoro- + carbon.
