Written question asked by Lord Berkeley (Labour), in the House of Lords. It was answered by Lord Adonis (Labour) on Monday, 26 October 2009.

Vehicles: Carbon Emissions

Question: To ask Her Majesty's Government further to the Written Answer by the then Minister of State at the Department for Transport, Stephen Ladyman, on 25 June 2007 (Official Report, House of Commons, 522–3W), what are the current emissions figures for diesel and petrol engines.

Answer: The Written Answer of 25 June 2007 gave air quality and carbon dioxide emissions expressed as fleet average emissions in grams per kilometre, broken down by vehicle type. The Department for Transport does not hold an updated version of this information using the latest modelling assumptions. However, an emissions factor demonstration tool, enabling users to produce similar estimates, was published as part of research on updating vehicle emissions inventory modelling assumptions, on 29 June 2009. This is available on the department’s website at http://www.dft.gov.uk/pgr/roads/environment/emissions/.
