HC Deb 30 November 1998 vol 321 cc50-1W
Mr. Baker

To ask the Secretary of State for the Environment, Transport and the Regions what estimate he has made of the emissions of NOx, from aircraft operating within United Kingdom airspace in each year since 1980. [60930]

Ms Glenda Jackson

No such estimates are produced for the whole of United Kingdom airspace. An annual estimate is made of the NOx produced by civil aircraft, on domestic or international flights at UK airports, during ground movements and in the landing and take-off cycle, up to 1,000 metres. This is published in the Digest of Environmental Statistics. Information from the Digest for the period 1980 to 1996 (the latest year for which figures are available) is given in the table:

NOx Emissions 1980–1996
Thousand tones
1980 10
1981 9
1982 10
1983 10
1984 11
1985 11
1986 11
NOx Emissions 1980–1996
Thousand tones
1987 12
1988 13
1989 14
1990 12
1991 14
1992 14
1993 15
1994 15
1995 16
1996 17

The UK has played a major part in securing reductions in NOx emissions in standards set by the International Civil Aviation Organisation and will continue to do so.
