I respect the figures which the hon. Gentleman has given. I do not disagree with them. The central point I was making was that we are now concentrating on less and less efficient uses of fuel in our transport strategy. For example, over the past decade the amount of tonnage carried by road has gone up 40 per cent. but the amount of ton mileage has gone up 67 per cent. That shows that, on the hon. Gentleman's figures, we are all the time moving to a less efficient form of transport in terms of fuel consumption.
