HC Deb 04 March 1997 vol 291 c600W
Mr. Martyn Jones

To ask the Secretary of State for the Environment what has been the change in nitrogen oxide emission levels over the last 20 years; and if he will make a statement. [18016]

Mr. Clappison

Emissions for nitrogen oxides were 2,206 kilotonnes and 2,218 kilotonnes for 1974 and 1994 respectively. Emissions of nitrogen oxide peaked in 1989 at 2,728 kilotonnes. The 1994 figure represents a 19 per cent. reduction on the 1989 peak. Further information can be found in the Department of the Environment's "Digest of Environmental Statistics 1996", a copy of which has been placed in the Library of the House.
