Finance (No. 3) Bill

The premise that my hon. Friend puts forward is absolutely right. The fact that more and more people are using low-emission vehicles will obviously have an impact. However, the purpose of the review proposed in the amendment is to consider what effects the fiscal changes will have. If the price of fuel is raised, some people will consume the same amount of fuel anyway because they are in business and they do not want to contract their business, but generally speaking it has a marginal effect. Private motorists will reduce the number of discretionary journeys they make by trying to take their cars to the shops less frequently and perhaps abandoning some leisure trips, and businesses will look for ways of economising as prices rise. I have heard the Minister's comments and I am grateful to her for drawing my attention to the estimate that the Government have made, but it is a fairly bald statement and it does not answer my question about whether the measure is driven by the Government's environmental concerns or their revenue-raising concerns, and we need a clear answer on that.
