Heathrow (Third Runway)

The rest of industry would have to bear a bigger burden. That is true, but I have explained to the hon. Gentleman why the Committee on Climate Change thinks that is right. We are the only party in the House that has a clear position—an internationally leading position on aviation emissions. We say that by 2050, aviation emissions must be back to current levels. That is a target consistent with the 80 per cent. target. Why is that significant? Because for the first time we are saying that aviation expansion is conditional on improvements and reductions in carbon emissions. That is a significant commitment. The right hon. Member for Suffolk, Coastal thinks that we will have trouble at the international negotiations on the matter, but we will be in a world leading position in the international negotiations when we enunciate our policy. I will have trouble though persuading other countries to sign up to the target, because it is such an ambitious target.
