HC Deb 24 November 1971 vol 826 c358W
55. Mr. Sutcliffe

asked the Secretary of State for the Environment what assistance he is giving to research into methods of reducing the level of sulphur dioxide emitted into the atmosphere as a result of the burning of fuel.

Mr. Peter Walker

As far as low-level emissions are concerned what is most needed is not research, but action. This I am stimulating by pressing people to go ahead with smoke control. As regards power stations and other high-level emitters, I am considering whether any current research project merits financial support.
