I refer the hon. Member to the answer I gave to him on 26 June 2008, Official Report, column 427W.
The Government remain committed to reducing the average emissions of the Government fleet to 130g/km by 2010. The range of vehicles commercially available which produce low carbon emissions is increasing and a number of new or improved models are expected to be released over the next year. GCDA is therefore reviewing the low carbon vehicles which may be suitable for use by Ministers as remaining older cars are replaced.
