Airports Commission: appraisal framework

The appraisal framework sets out in detail how the Airports Commission expects the scheme designs for additional airport capacity announced in December to be developed, and how the schemes will be appraised. This consultation invites responses on the draft framework which consists of 4 inter-related elements:

• the Commission’s objectives, against which options will be assessed and on which its final recommendations will be based
• a refreshed scheme design for each short-listed option, to be used as the starting point for appraisal
• a business case and sustainability assessment for each option, incorporating the information needed to make informed assessments against the Commission’s objectives
• a set of appraisal modules explaining the methodologies that the Commission proposes to use in assessing options
