L'equità degli impatti dei provvedimenti di road pricing

The studies on urban sustainability policies have focused on the analysis of environmental externalities from other sectoral policies. On the contrary, rarely (quite never in Italy) the analysis has been made in the opposite direction, that is in order to understand what are the externalities and, among others, the socio-economic impacts of environmental policies. The present paper aims to contribute to this subject. Till now studies have shown that, probably, a 'unique' answer - a priori truthful does not exist, but the effects of every policy need to be analyzed on the basis of the different contexts. With this background, the introduction of urban road pricing schemes is studied (i.e. the pollution charge) in order to evaluate, not only the environmental effects, but also the socio-economic impacts. Among these, the equity effects and the redistributive effects of environmental policies are carefully evaluated, that is, trying to understand the way ongoing policies affect different groups, above all income groups.
