HC Deb 05 March 1984 vol 55 cc430-1W
Mr. Skeet

asked the Secretary of State for the Environment (1) what is Her Majesty's Government's policy towards encouraging the use of catalysts to convert toxic exhaust gases into innocuous substances;

(2) what is Her Majesty's Government's policy towards the redesign of vehicle engines to promote concurrently fuel economy and clean emissions.

Mrs. Chalker

I have been asked to reply.

Vehicle manufacturers are now taking steps to conform with Community directive 83/353/EEC which will substantially lower pollution from petrol engined vehicles over the next few years, at a small cost in terms of fuel economy. We welcome the efforts of United Kingdom manufacturers to develop more fuel efficient engines using new technology which, I understand, will enable further reductions in pollution to be made in the longer term. The catalytic control devices now available are expensive, would worsen fuel economy and add about £2,000 million per year to United Kingdom motoring expenditure; such expenditure is not justified to deal with emissions from petrol engined vehicles in the United Kingdom. Other changes are necessary to reduce smoke from diesel engined vehicles, and we shall be making proposals on this later this year.
