HC Deb 22 May 1989 vol 153 c384W
Mr. Bermingham

To ask the Secretary of State for the Environment what proposals his Department has for controls on the production and use of the compounds methyl chloroform and carbon tetrachloride; and if he will make a statement.

Mrs. Virginia Bottomley

Although methyl chloroform is significantly less damaging to ozone than the chorofluorocarbons (CFCs), its world-wide production is greater than for any single CFC. Production of carbon tetrachloride is lower, but its potential to deplete ozone is greater than that of the CFCs. Review panels on the science and effects of ozone depletion and on the technical and economic implications of controls are due to report later this year to the parties to the Montreal protocol, who will decide at their meeting in London next year on measures to strengthen the protocol, including the possible inclusion of additional substances.
