M6: M42

Volume 503: debated on Thursday 14 January 2010

To ask the Minister of State, Department for Transport what estimate he has made of the average annual consequential carbon dioxide emissions arising from the hard shoulder running schemes on (a) the M6 and (b) the M42. (310142)

[holding answer 11 January 2010]: No estimates have been made of average annual carbon dioxide emissions following the introduction of hard shoulder running on the M6 and M42. Desk studies have been carried out by the Highways Agency, based on a calculation of engine characteristics of vehicles using the pilot scheme on the M42. These have shown that emissions have reduced by 4 per cent. per vehicle as a result of a reduction in stop/start traffic conditions.
