Heathrow (Third Runway)

I made it clear in my statement to the House that any further expansion beyond that which was permitted would require a new process by which any new slots would be made available. That process would depend critically on the views of the Committee on Climate Change, which would have to report to the Government, and therefore indirectly to the House, that we were on track—that is, that we were taking the right decisions—to meet our ambition of ensuring that there would be no more carbon emissions through aviation in 2050 than in 2005. That is a clear commitment to take account not only of the advice of the committee but to ensure that it will advise the Government on the necessary steps to meet that ambition.
