Heathrow

It might well do so. Another factor is the price of travel. According to a parliamentary answer that I received from the Government—of course, we must believe Government statistics—the average cost of a one-way flight in the United Kingdom has declined from £205 in 1997 to £103 today. In other words, the cost of domestic flights has halved. Meanwhile, the cost of travelling by rail, which is much more carbon-friendly, has increased by more than the rate of inflation, and the Government refuse to rule out further above-inflation increases. They have stuck to the RPI plus 1 formula—RPI plus 3 for those who happen to live in the wrong part of the country—driving up rail prices while air prices are cut. That is not a sensible climate change policy, by any stretch of the imagination. Climate change is an important issue, which was rightly raised by both the hon. Member for Hayes and Harlington and the hon. Member for Chipping Barnet (Mrs. Villiers). I am pleased that the Government have introduced a climate change Bill, and I congratulate them on the fact that ours is the first country in the world to introduce such legislation. That is a matter for consensus. I am equally delighted that the right hon. Member for Scunthorpe (Mr. Morley)—along with others, including my colleagues—has helpfully managed to persuade the Government to increase their 60 per cent. target to an 80 per cent. target. All that is good news. We need an 80 per cent. target, because the climate change challenge that we face is enormous. But how can it possibly square with the construction of an extra runway at Heathrow? How does it square with the predict and provide policy that the Government seem so determined to maintain? How does it square with the additional flights, increased pollution and increased carbon emissions that will inevitably accompany an increase in the number of flights from Heathrow? The Government are talking about almost doubling the number of flights. How does that square with an 80 per cent. cut in carbon emissions?
