Question to the Department for Transport:

To ask the Secretary of State for Transport, in preparing the Heathrow Expansion Appraisal Report, what consideration her Department gave to modelling the potential monetised costs of noise pollution from expansion.

The Heathrow Expansion Appraisal Report estimates monetised disbenefits of noise to be approximately -£1.6 billion (2024 prices) over a 60-year appraisal period. This reflects the estimated increased noise exposure causing health, annoyance and sleep disturbance impacts.
