HC Deb 18 July 1994 vol 247 c41W
Mrs. Bridget Prentice

To ask the Secretary of State for the Environment what evidence he has received about the impact of vehicle emissions on air quality in London.

Mr. Atkins

The London energy study carried out by the London Research Centre was published on 15 September 1993. It was funded by the European Commission, London Electricity plc and the Department of the Environment. One of the principal outputs of the study was a very detailed inventory of energy use, and the resultant emissions of pollutants to the London atmosphere covering almost 2,000 sq km in and around London. The table illustrates the contribution from road transport for each pollutant in 1991.

London road transport 1991
Percentage of total emissions
Carbon dioxide (as carbon) 33
Sulphur dioxide 22
Black smoke 96
Carbon monoxide 99
Nitrogen oxides 76
Volatile organic compounds 97
