§ Mr. MackinlayTo ask the Secretary of State for the Environment, Transport and the Regions what are the projected increases of emissions of(a) carbon monoxide, (b) nitrogen oxide and (c) PM10 particles consequent on the proposed widening of the M25 between junctions 12 to 15; and if he will make a statement. [6339]
§ Ms Glenda Jackson[holding answer 1 July 1997]: Taking 1991 as the base year and 2010 as the forecast year, morning peak hour carbon monoxide emissions from vehicles on the M25 are predicted to decrease by approximately 72 per cent. with the widening scheme compared to 70 per cent. without the scheme. Emissions of oxides of nitrogen are predicted to decrease by approximately 84 per cent. compared to 72 per cent. without the scheme. PM10 concentrations are predicted to decrease by 38 per cent. compared to 51 per cent. without the scheme.
