Rt Hon Lord Lilley

    Lord Lilley: My Lords, of all the ways of restricting carbon dioxide emissions from air travel, is not restricting the capacity of airports the silliest? Its main consequence would be that more planes would be stacked up above busy airports, using more fuel, and all other flights to those destinations would have to carry more fuel just in case they were stacked up too.

    Baroness Vere of Norbiton: I agree with my noble friend that there are many ways that we can tackle carbon emissions. He mentions stacking. That is why we are taking forward the airspace modernisation plan, which will have capacity benefits for airports, reduce costs for airlines and reduce delays for passengers—because stacking will become a thing of the past.
