Several types of car-sharing options exist (freefloating or round trips), 6 companies operate in Grand Paris Metropolis and car-sharing is gradually increasing bit by bit, as opportunities arise and local policy objectives evolve. At the beginning of 2025, car-sharing services were available in 21 municipalities. In 2024, three others launched Calls for Expressions of Interest (CEI), aimed at developing this type of activity. The study describes the present-day situation of car-sharing on offer in Grand Paris. It also looks at numerous services running in other metropolises (Brussels, Lyon, Nantes) and analyses data on the use of car-sharing in Grand Paris, as well as the typical profiles of people who currently use the service.
Although car-sharing seems to be an interesting option, with less financial impact for people who only occasionally use a car, it remains restricted by psychological and cultural parameters (attachment to ownership, not knowing the car borrowed, fear of non-availability, lack of offers and prices). It would therefore be pertinent to accompany this mobility service and to facilitate its development.
