HC Deb 01 February 1990 vol 166 c260W
Mr. Alton

To ask the Secretary of State for Energy how many tonnes of(a) sulphur dioxide, (b) nitrogen oxides and (c) particulate carbon are discharged into the atmosphere as a result of electricity generation each year.

Mr. Baldry

In 1987 a total of 2,830,000 tonnes of sulphur dioxide and 809,000 tonnes of nitrogen oxides were emitted in the United Kingdom as a result of electricity generation. The reference to particulate carbon in the question is taken as meaning black smoke; coal-fired power stations employ a high-temperature combustion process which avoids the emission of black smoke during electricity generation.

These figures have been taken from the "Digest of Environmental Protection and Water Statistics", a copy of which is in the Library of the House. Figures for 1988 will be available in the next edition of the digest which will be published soon.
