HC Deb 04 July 1975 vol 894 c566W
Mr. Knox

asked the Secretary of State for the Environment whether he intends to introduce more stringent legislation to control the emission of exhaust pollution by lorries.

Dr. Gilbert

I am looking at the question of further controls on the emission of exhaust pollution by dieselengined vehicles. I recognise also that there are problems in ensuring that production vehicles conform to the standards already set. We are also taking part in international discussions on the need to control emissions of sulphur and nitrogen oxides, and the technical standards that would be required.
