This METROAirports report is the continuation of the Sustainable Airport Areas project, which was carried out between 2015 and 2017 under the leadership of IAU. This initiative resulted in the publication of a report entitled “Sustainable Airport Areas. Guidelines for Decision Makers”. This project represents an attempt to further conceptualise the notion of “airport area” and to broaden the perspective beyond the scope of previous research, which had focused mainly (but not exclusively) on airports and airport cities. The project has focused on three aspects related to airport areas, namely: (i) planning, (ii) governance, and (iii) economic development and employment policies.
