§ Mr. FallonTo ask the Secretary of State for the Environment, Transport and the Regions how many more vehicles now run on ultra-low sulphur diesel than in April 1997. [26352]
§ Ms Glenda JacksonNo data are available on the total number of vehicles using ultra-low sulphur diesel. However, very approximate estimates suggest that the ultra-low sulphur diesel share of the diesel fuel market has risen from about 1 per cent. in April 1997 to about 2.5 per cent. today.
