Enhancing Public Acceptability of Low Emission Zones: The Role of Accompanying Measures
Résumé
Low Emission Zones (LEZs) suffer from a lack of public support, which can hinder their implementation or decrease their environmental ambition. Although the individual determinants influencing this support have been studied, the leverage effect of accompanying measures remains unexplored. Accompanying measures also serve as a support tool for vulnerable households and thus influence not only the acceptance of the LEZ but also social justice.We study the public acceptability of a LEZ prior to its implementation in Grenoble (France), and the perception of accompanying measures aimed at facilitating modal shift, introducing exemptions or proposing subsidies for the purchase of LEZ-compatible vehicles. This work highlights the heterogeneity both among supporters and opponents in the perception of the usefulness of these measures, identifies the most relevant measures according to profiles of respondents. This is the first work to analyze support measures for LEZs in a way that endogenously identifies profiles of people.
