How to structure the public debate on the low-carbon future of passenger transport?

Different communities of stakeholders have strong opinions about the long-term evolution of the transport sector and argue for specific visions of the low carbon transition consistent with their own situations and priorities.
A key challenge for organizing debates around these alternative visions is that they are very difficult to contrast and compare in the light of common public questions and to assess against their consistency with all national objectives.
This issue analyses how building consistent long-term pathways for the low-carbon future of the passenger transport sector and making them comparable in a transparent manner are key challenges for structuring productive public debates.
