I thank the Secretary of State for her statement, which made the Government’s intent of supporting the proposed third runway at Heathrow very clear. It was good to hear her recognise the complexity of all that will be needed to deliver it, including major diversionary works on two of the country’s busiest motorways. We Liberal Democrats continue to support the right infrastructure in the right place, which is why we have always supported schemes such as East West Rail and Northern Powerhouse Rail. However, we need the right infrastructure to tackle the right problems, and there are many unanswered questions about the Heathrow third runway. The New Economics Foundation has been very clear in its analysis that the environmental impact of airport expansion will erode a lot of our carbon emission reduction plans, and many studies have questioned the economic case for Heathrow expansion. I would be interested to hear from the Secretary of State about the dangers of relying solely on the private sector to fund large schemes, as happened in the case of the channel tunnel, which remains an enormously underused asset, partly because of the costs that resulted from the decision to fund it only through the private sector. It is welcome that the Secretary of State has made her support for Heathrow expansion subject to four tests, but I detect perhaps a slight hint of cognitive dissonance, and a contradiction in the Government setting out timelines for delivering something that they say is subject to four tests. The Secretary of State said that she would hear the independent advice of the Climate Change Committee. If the CCC decides that the preferred option for the Heathrow third runway is incompatible with our carbon emissions and our net zero targets, will she drop her support for the third runway?
