The EU Commission has set the goal of facilitating a competitive transport system, increasing mobility and supporting growth while simultaneously reaching a target of 60 per cent emissions reductions by 2050. In light of past performance and estimated development, the target will not be reached without further behavioural change in the transport sector. This interdisciplinary book examines how such a behavioural shift can be achieved by various organizational and legal means, focusing primarily on the European Union and its specific policies related to greening transport.
