The Government and the Treasury keep all taxes under review, and were contrary evidence to emerge, we would of course look at it and, if necessary, adapt the policy. We have, however, made a judgment on the evidence before us, and consumer research demonstrates that first-year incentives are by far the most important when customers come to choose new cars.
The hon. Member for Salford and Eccles asked why the Government are now taxing plug-in and hybrid vehicles the same as conventionally fuelled cars. Such cars will still benefit from cheaper rates. The updated CO2 banding on first-year rates in the new VED system will strengthen the incentive to purchase the cleanest cars, including plug-in and hybrid vehicles. As I have said, the evidence suggests that up-front incentives are the most effective in influencing behaviour. We will continue to support hybrids and plug-in vehicles with beneficial rates of company car tax and enhanced capital allowances, as well as through the plug-in car grant. The Government have guaranteed that £5,000 grant until February 2016.
Our longer-term plan will be announced after the spending review. To drive down carbon emissions and air pollutants, we will give the greatest incentives to zero-emission cars—those that produce no air pollution or CO2 whenever they are driven—which pay no VAT.
