HC Deb 23 June 1971 vol 819 c294W
Mr. Loveridge

asked the Secretary of State for the Environment if he will now take steps to ensure that the fumes from diesel exhausts are reduced on British roads.

Mr. Peyton

Draft regulations were published last December requiring that all new diesel-engined vehicles should conform to British Standard BS AU141. The standard specifies a strict limit on smoke emission.
