He has studied interrelationships of tourism, transport, and sustainability for a quarter of a century.
In the early 1990s, his work focused on aviation and the sector’s contribution to emissions of greenhouse gases. Since then he started to investigate a wide range of different transport modes from diverse scientific perspectives, including the car, bicycle, and e-scooter.
He is specifically interested in climate policy and transport governance; ICT in tourism, transport, and mobility contexts; transport economics; urban planning; and social norm change in consumer cultures. Mostly in interdisciplinary frameworks embracing geography, economics, sociology, and psychology.
His work has been conducted in a wide range of cultural and geographical settings in the European Union, the Middle East, East Africa/Western Indian Ocean, and the Caribbean. Has also worked as a consultant on behalf of numerous governments and companies, as well as supranational organizations including UNWTO, UNEP, UNDP, OECD, and World Bank.
