Question to the Department for Transport:

To ask the Secretary of State for Transport, with reference to Table 9.2 of her Department's report entitled Updated Appraisal Report: Airport Capacity in the South East, published in October 2017, whether it remains her Department's estimate that the net present value of a Heathrow northwest runway has a high of £3.3billion and a low of minus £2.2billion.

The latest published information on the net present value of a Heathrow Northwest runway is contained in the “Addendum to the Updated Appraisal Report” published June 2018 which updated the Department’s estimate to a net present value of £2.9bn to minus £2.5bn in 2014 prices[1]. Economic benefits as reported in the Updated Appraisal Report also fed into the Airports National Policy Statement (ANPS).

The Department has committed to reviewing and updating the ANPS, and has invited proposals for a third runway to be brought forward by the summer. Once proposals are received, the government will review the Airports National Policy Statement (ANPS) which provides the basis for decision making on granting development consent for a new runway at Heathrow.
