§ Mr. Ron Daviesasked the Secretary of State for Trade and Industry, pursuant to his answers of 2 March and 24 March, on what currently available information the Government base the scale of Britain's contribution to ozone depletion and the consequent effect of a freeze or reduction in the production and use of chlorofluorocarbons or other agents responsible for the phenomenon.
§ Mr. Giles ShawDepletion of the ozone layer is a global problem and cannot be attributed to individual countries. It is not possible to quantify the effect of a single country taking precautionary measures to limit omissions of potential ozone depleting substances.
