17:34 The Minister of State, Department for Transport (Mrs Theresa Villiers)

Despite the valiant efforts of my hon. Friends the Members for South Northamptonshire, and for North Warwickshire, and the hon. Member for Coventry North West, the opponents of HS2 have not made a convincing case that there is a better way of dealing with the expected growth in demand for inter-city travel. My hon. Friend the Member for Warwick and Leamington (Chris White) suggested that information technology will provide the answer. I certainly hope that future advances in technology will make video-conferencing an alternative to more journeys, but I am afraid that after in-depth research, the Committee on Climate Change concluded that the net impact of such technology on travel is likely to be minimal, and I am afraid that improvements to the existing network just cannot provide the capacity that HS2 would. The Government are already committed to delivering a 30% uplift in capacity on the west coast line, with new carriages being introduced from April 2012, but that will simply not be enough to meet the demand for inter-city travel in the decades to come.

Lastly, I will address the allegation that high-speed rail is not green and offers no environmental benefits. Our analysis shows that the shift from road and aviation that would come with delivering the west midlands section of the line would broadly offset any increase in carbon emissions from the new line, despite the significant increase in passenger journeys that it would accommodate. We would get a major economic boost without increasing carbon emissions, which is just the sort of sustainable growth most people in the country say we should have. The modal shift resulting from the Y-shaped network to the north of England would be greater still, with as many as 6 million journeys by air and 9 million by road expected to migrate to rail. The carbon benefits of rail over aviation are set to grow as we make progress on decarbonising the electricity supply.
