Cars: Exhaust Emissions

Volume 477: debated on Friday 13 June 2008

To ask the Secretary of State for Transport pursuant to the answer of 22 April 2008, to the hon. Member for East Yorkshire, Official Report, column 1894W, on cars: research, how much expenditure her Department has incurred in testing vehicle emissions for the purposes of national emissions inventory modelling in the last three years; and by whom such testing has been conducted. (209252)

Expenditure by the Department on emission factor testing and analysis for the purpose of the national atmospheric emissions inventory model in the last three financial years (2005-6, 2006-7 and 2007-8) amounted to some £279,860. This work was carried out by Shell Global Solutions (UK), Tickford Powertrain Test Limited and AEA Technology PLC. Copies of the resulting reports may be found on the Department's website at

www.dft.gov.uk/pqr/roads/roads/environment/research/cqvcf

or by navigating from the Department's home page (www.dft.gov.uk) to DfT home > Policy, guidance and research > Roads and vehicles > Environmental issues > Research > Cleaner and Quieter Vehicles and Cleaner Fuels.

A small amount of emissions factor testing work has also been carried out in the course of the Department's annual enforcement programme of checks on manufacturers' production.

In addition, some £110,000 of expenditure was incurred on research into improved methodologies for emissions modelling.

This was undertaken by the Transport Research Laboratory.
