§ Miss McIntosh
To ask the Secretary of State for Transport what action the Government are taking to improve air quality, with particular reference to use of alternative road fuels. 
§ Mr. Jamieson
Alternative fuels receive considerable support from Government, in the form of significant fuel duty incentives, grants for vehicle conversions under the PowerShift Programme, and reduced rates of Vehicle Excise Duty and company car tax for cleaner vehicles. In the December 2003 pre-Budget report, the Chancellor published the Alternative Fuels Framework, which sets out the basis on which support will, in future, be provided for clean, low carbon road transport fuels. In particular, it includes a commitment to provide three-year certainty on duty differentials for all alternative fuels from Budget 2004.
