§ Mr. Andrew SmithTo ask the Secretary of State for the Environment what information his Department collects on the emission of gases damaging to the ozone layer from(a) aircraft, (b) road vehicles and (c) other sources; and what the most recent statistics indicate in respect of such emissions.
§ Mr. TrippierThe approach of the Montreal protocol, and that of the European Community, is to control the supply to the market, rather than the emission, of ozone-depleting substances. We do not therefore need to collect data on emissions.
