§ Mr. Simon Hughes
To ask the Secretary of State for the Environment what steps he is taking to eliminate the use of ozone-depleting substances in(a) refrigerants, (b) solvents and (c) foams; and if he will make a statement.
§ Mr. Trippier
The ozone layer can be protectd only by international action. The Montreal protocol is due for revision in June. We are pressing for rapid cuts in the supply of CFCs, halons and carbon tetrachloride, with their elimination by the year 2000. Methyl chloroform must also be cut substantially. If the revised protocol is not strong enough, we will press for further restrictions within the European Community.
