e-Digest Statistics about: Ozone Depletion
World and UK production of CFCs: 1986-2005
United Kingdom and World
There is unequivocal evidence that man-made emissions of substances containing chlorine and bromine deplete the stratospheric ozone layer. In 1987, international agreement to limit the production and consumption of the most important of these substances was reached in the Montreal Protocol. This has brought about substantial reductions in their production and consumption. World production of chlorofluorocarbons (CFCs) fell by 94 per cent between 1986 and 2005.
In the UK, production and consumption of CFCs had ceased by 1995. UK manufacturers have CFCs manufactured under licence overseas for essential uses such as metered dose inhalers and laboratory or analytical purposes. However, these substances have a long life in the atmosphere, and it is anticipated that recovery of the ozone layer will not occur until the middle of the 21st century.
