§ Mr. Chris Smithasked the Secretary of State for Energy (1) if he will estimate, for the first 5 per cent. of a reduction of 60 per cent. on 1980 levels of sulphur dioxide emissions from power stations in the Central Electricity Generating Board system, by 1995, what the cost of sulphur abated per tonne would be through (a) electricity or energy conservation, (b) flue gas desulphurisation, (c) substitution of nuclear power by commissioning new plant and (d) coal washing;
(2) what information he has as to the number of fossil fuel power stations which would need to be fitted with flue 182W gas desulphurisation equipment if sulphur dioxide emissions from this source were to be reduced by (a) 30 per cent. (b) 60 per cent. and (c) 80 per cent.
