Résumé : In this policy brief, we propose a tool that could be used by different actors, including public institutions, to evaluate the state of socio-ecological inequalities in the context of just transitions. In the Brussels-Capital Region where just transition has become a guiding principle of climate policy, this tool is aimed at supporting the implementation of the main just transition commitments made by the regional government to assess the current state of environmental and social inequalities and identify levers to reduce them.
