Ecologists’ own goal: ozone saver is global warmer - Times Online
THE green movement’s greatest triumph – the abolition of ozone-destroying CFC gases in the 1980s – may become its biggest embarrassment because of research showing that their replacements are sharply accelerating global warming.
CFC, or chlorofluorocarbon, gases were widely deployed in air-conditioning and refrigeration units before they were found to destroy the ozone layer and banned under the 1987 Montreal protocol.
They were replaced by HFCs – hydrofluorocarbons – gases that have far less effect on ozone but have since been revealed as extremely powerful greenhouse gases.
A ton of HFC23 used in refrigeration has the same global warming potential as 14,800 . tons of CO2
