Abstract: Social (in)justice is an argument often put forward to explain the successive setbacks to the roll-out of low-emission zones (LEZs) in France. However, until now, this is not based on any rigorous assessment. We are developing a methodology for assessing the impact of a LEZ on mobility vulnerabilities based on a multidimensional vulnerability indicator (VulMob). We apply this methodology to the Grenoble region. Firstly, we show that the number of households without a solution is extremely low and that there are solutions to help these households specifically, without calling the whole policy into question. Moreover, modal shift appears to be a high-potential adaptation solution for all households, which could improve the environmental and health performance of the LEZs. It should be noted, however, that highly vulnerable households are more affected and more likely to remain without a solution other than buying a car that complies with the LEZ. This work can guide the operational implementation of the LEZs and the definition of support policies, taking into account vulnerability profiles and the specific characteristics of the area.
