HC Deb 15 December 1971 vol 828 c91W
18. Mr. Grylls

asked the Secretary of State for the Environment whether, as part of his review of pollution from motor vehicles, he will have consultations with the motor trade with the aim of encouraging the introduction of pollution-free exhaust systems.

Mr. Peter Walker

I shall shortly be announcing what controls on emissions from petrol-engine vehicles I consider necessary as a result of my review. I shall then have consultations both about the implementation of those controls and about the prospects of achieving more rigorous standards in the longer term.
