On the back of sustained double digit growth in passengers and freight, investment in airports is booming. Similarly, occupational demand for airport-related property has seldom been stronger and active requests for investment product abound. Industry forecasts for continued strong growth in passengers and freight have lead investors to assume that this is a one way bet. One the other hand, environmentalists at all levels continue to decry growth in air travel, for goods and people, as a major contributor to global warming. These concerns are starting to manifest themselves in legislation. This paper takes a critical look at present and future investment in both airports themselves and airport-related property across Europe. Scenarios for future performance are proposed, taking into account different political, economic, social and technological outcomes.
