HC Deb 14 March 1995 vol 256 cc536-7W
Mr. Ainger

To ask the Secretary of State for the Environment what were annual actual emissions of(a) nitrogen dioxide, (b) sulphur dioxide, (c) all oxides of nitrogen and (d) particulates from each of the fossil-fuelled power stations operating in (i) 1980, ii) 1984, iii) 1985 and (iv) each year since 1990.

Mr. Atkins

I enclose details of the emissions from power stations that Her Majesty's inspectorate of pollution holds centrally and which have been placed on the large combustion plant directive inventory. These are the S0,2 NOx and particulate emissions from National Power and PowerGen for 1991 to 1993—emission data on particulates are held only for 1993. The 1994 emissions are not yet available.

Data for total emissions from power stations have been compiled within the national atmospheric emissions inventory by the National Environmental Technology Centre, formerly Warren Spring Laboratory. Available information. for 1980, 1984 and 1985 is given.

The other information requested was not collected for previous years.
