§ Mr. Nigel JonesTo ask the Secretary of State for the Environment, Transport and the Regions what assessment he has made of the level of air pollution caused by emissions from vehicles which are more than 25 years old. [103156]
§ Mr. HillVehicles over 25 years old, although manufactured to much less stringent emission standards than vehicles today, are estimated to make only a small contribution to total emissions from road transport, due to their low numbers and limited mileage. The table provides estimates of the contribution of cars in this category for three key pollutants, using the methodology employed in the National Atmospheric Emission Inventories.
Pollutant Estimated contribution of cars over 25 years old to overall emissions from road transport in 1998 NOx 0.7% PM10 0.4% CO 1.3%
