Details
The Appraisal of Sustainability (AoS) systematically identifies, describes and evaluates the likely significant social, environmental and economic effects of the draft Heathrow Expansion National Policy Statement (HENPS). It also analyses the reasonable alternatives to the Northwest Runway scheme.
The AoS informs policy preparation by ensuring that sustainability considerations are considered and clearly presented to decision-makers and consultees.
The AoS forms part of a wider suite of technical assessments undertaken to inform the draft HENPS, alongside the:
- Equality Impact Assessment (EqIA)
- Habitats Regulations Assessment (HRA)
- Health Impact Analysis (HIAn)
The Department for Transport (DfT) commissioned AECOM to prepare the AoS.
