  • Road decarbonization: an ecological emergency
    Christophe SAINTILLAN (Vinci Autoroutes, France) - Deputy Managing Director

Christophe SAINTILLAN currently is Deputy Managing Director of VINCI Autoroutes, France's leading freeway concession company, in charge of 4,400 km of motorway. Previously, he was with the French Ministry of Transport for twenty years, in charge of various road design, road policy and infrastructure management roles. He was a Member of the PIARC Executive Committee from 2010 to 2016 and First Delegate for France. He joined the Great Paris (Île-de-France) regional council for 4.5 years, where he was in charge of housing and transport.

Christophe Saintillan presented how VINCI Autoroutes address decarbonization and adaptation. VINCI Autoroutes has been working with academics on the decarbonization of the road: starting from the observation that in France, the transport sector has become the most emitting sector and the only one whose emissions are not being reduced, Vinci Autoroutes has studied the concrete actions to be taken to bring mobility on freeways in line with the trajectory imposed by the Paris Agreement and French national policies. These include welcoming electromobility for light vehicles (massive installation of charging stations) and heavy goods vehicles (charging stations, ERS), encouraging the most virtuous modes of transport (car-sharing, public transport thanks to reserved lanes, parking facilities and multimodal platforms) and, more generally, making freeways part of a logic of urban and environmental integration and adaptation to climate change, given their impact on the weather (reducing the consequences of flooding, protection against the risk of fire). This calls for a massive and urgent investment plan, broken down by action and costed.
