§ Mr. Simon Hughes
To ask the Secretary of State for the Environment what targets his Department has identified as desirable in respect of cuts in the supply of(a) CFCs, (b) halons, (c) carbon tetrachloride and (d) methyl chloroform.
§ Mr. Trippier
[holding answer 30 April 1990]: We must reduce production and consumption of all ozone-depleting substances as quickly as possible. In international 506W negotiations we are pressing for: CFCs and carbon tetrachloride to be cut by 85 per cent. by 1995–96, and 100 per cent. by 2000; halons to be cut by 50 per cent. by 1995, and 100 per cent. by 2000 with exceptions for some essential uses; and methyl chloroform to be cut by 25 per cent. by 1994 with decisions to be made then on further cuts. We are considering whether we can go further and faster on methyl chloroform and carbon tetrachloride.
