§ Dr. ThomasTo ask the Secretary of State for Transport what estimates he has made of the amount of carbon dioxide which may be emitted from the existing heavy goods vehicle fleet during its remaining lifetime.
§ Mr. ChopeThe latest available figure is 28,000 tonnes per annum for 1988 and relates to total carbon dioxide emissions from all road vehicles. No breakdown of this figure between vehicle types is available. The remaining life of the existing heavy goods vehicle fleet depends on varying factors and cannot be predicted with accuracy.
