Draft Heathrow Expansion National Policy Statement Health Impact Analysis

The Health Impact Analysis (HIAn) provides a systematic analysis of how the draft Heathrow Expansion National Policy Statement (HENPS) may impact health across the population, including vulnerable groups. The findings support decision-makers by providing an evidence-based understanding of potential health impacts.

The HIAn for the draft HENPS builds on the 2018 HIAn for the Airports National Policy Statement (ANPS).

The Department for Transport (DfT) commissioned AECOM to prepare the HIAn.
