HC Deb 16 June 1971 vol 819 c81W
19. Sir B. Rhys Williams

asked the Secretary of State for the Environment what further steps he will now take to procure a reduction in the emission of smoke and harmful fumes from motor vehicles, including vehicles propelled by diesel oil and petrol.

Mr. Peter Walker

I have already published a draft regulation to control smoke from new diesel-engined vehicles, and a regulation has been made requiring all new cars to have a device eliminating fumes from the crank case. I am actively considering the complex question of exhaust fumes from petrol-engined vehicles.
