Dealing with the airport and its environment

Issue 5 2010  •  1 October 2010  •  Hamsa Balakrishnan, John-Paul Clarke, Eric Feron, and Marc Pélegrin

Airport infrastructure capacity is rapidly being approached in many cities around the world. Environmental factors, such as acoustic and chemical emissions, are increasingly less tolerated by neighbouring communities. The net result is that new means must be found that deliver more aircraft to the airspace with less environmental impact on the community, while maintaining the current level of safety enjoyed by air transportation. In this article, we investigate a few promising options to decrease the environmental footprint of airports.

This cost can be further segregated into a $6 billion impact upon direct airline operating costs and a $4 billion impact upon the value of collective passenger time.
