Mobility in transition


Road transport is responsible for 29% of France's CO₂1   emissions and a significant share of the pollutant emissions affecting air quality in cities and towns. The mobility and transport sector is key to the ecological transition and decarbonization. It is characterized by a particularly advanced maturity: technological solutions exist, most of them already competitive, and largely supported by a restrictive, well-defined and sustained regulatory framework, and by a supportive tax incentive framework that has proven its effectiveness in initiating the transition. In addition, the evolution of economic models and usage patterns is also underway. 

Created in 2021 by IDDRI and funded by the European Climate Foundation, the Institute Mobility in Transition aims to create the conditions for a successful transition in the sectors of passenger mobility and freight transport.

The work focuses on the decarbonization of mobility and road transport, air quality and the establishment of the associated ecosystem (charging and refueling infrastructures needed for new energies, dedicated industrial needs such as battery recycling, etc.). The works are based on three streams: the animation of a multi-stakeholder dialogue platform, the creation of an updated database of the sector to simulate and project the evolution of the fleet, and collaborations with French and European organizations to enlighten the understanding of decision-makers. The scope of activity is centered on France, but with the ambition to influence the debate and the European regulatory systems.

The Institute Mobility in Transition proposes a collaborative method to accelerate debates, public action and ultimately the transition, by mobilizing the knowledge and experience of various economic and industrial players, users, civil society, territories, and the academic world. The ambition is to create a protected and fluid space for dialogue between these different stakeholders in order to collectively identify the issues, the risks and propose solutions. This shared understanding, based on co-constructed data and analyses, will be used to develop recommendations for public decision-makers and to inform the public debate. 

The Institute is neither a place of consensus, nor a research bureau, nor an advocacy organization. It is a space for protected dialogue that must allow members to test their vision and their hypotheses, to make the debate more fluid, to anticipate obstacles in order to remove them, and in fine to secure the transition.
