§ Ms. Walley
To ask the Secretary of State for Trade and Industry what information he has on the number of tonnes of ozone-depleting chemicals produced in each of the last five years.
§ Mr. Forth
My Department receives data from the European Commission on the production within the Community of various of the substances controlled under the Montreal protocol. The two United Kingdom manufacturers of these substances copy the data they supply to the Commission to my Department and the Department of the Environment on a commercially confidential basis.
My officials have recently received industry data showing that total production of methyl chloroform (1, 1, 1-Trichloroethane) in the main industrialised regions (Western Europe, United States of America, and Japan) for the years 1985–89 was (in '000 tonnes):
Thousand tonnes 1985 588 1986 609 1987 627
Thousand tonnes 1988 678 1989 717
My Department has no data on the production of HCFCs, or any other ozone-depleting substances.
