In my book ‘New Mobility – Beyond the car era’ I predict that people in Western-Europe will in 2015 fly on average more kilometres than they travel by car. The strong growth in aviation causes an unwanted increase in global warming. Lessons from decades of policies for sustainable road traffic revealed only two effective policies: forcing clean technology and pricing. It is often argued that pricing policy for aviation contravenes the Treaty of Chicago from 1944 and gives rise to unacceptable economic distortions. However, already in 1998 a study has been carried out into the design of a European aviation charge, which is both economic and legal feasible. This research is again relevant.
