This special issue of Network Industries Quarterly is dedicated to the European Green Deal and its implications for the transport sector. In its long-term decarbonisation strategy ‘A Clean Planet for All,’ the European Commission paints a clear picture of the vast transformations that will have to take place across all sectors of the economy for Europe to become climate neutral by 2050. In its subsequent European Green Deal, Commission President Ursula von der Leyen reinforces this ambition and pledges to enshrine the climate neutrality objective into legislation. For transport, which accounts for a quarter of the EU’s total greenhouse gas emissions, achieving the climate neutrality objectives will require a 90% reduction of the sector’s emissions by 2050 compared to 1990 levels, with sizable contributions across all modes. Our invited contributors take a closer look at the concrete examples of rail, aviation, intermodal transport and Mobility-as-a-Service solutions, as well as at the increasing coupling and interdependence between the transport and the energy sectors.
