Question to the Department for Transport:

To ask the Secretary of State for Transport, what assessment her department has made of the potential impact of a third runway at Heathrow Airport on the economy; and what assessment her Department has made of the potential impact of the runway on environmental, social and climate-related costs.

As part of the recent consultation on the draft Heathrow Expansion National policy statement (now closed) the Department conducted analysis to look at the potential impact of Heathrow Airport expansion on the economy, including the environmental and climate related costs. This analysis can be found in the Heathrow Expansion Appraisal Report (HEAR) located here: Draft Heathrow Expansion National Policy Statement appraisal report - GOV.UK. The HEAR is supported by further economic impact modelling document located here: Heathrow expansion economic impact modelling - GOV.UK. A further assessment of the impact of the scheme can be found in the Appraisal of Sustainability located here: Draft Heathrow Expansion National Policy Statement Appraisal of Sustainability - GOV.UK.
