Inequalities in exposure to environmental hazards and access to environmental amenities have been documented in many cities, in relation to residential segregation of low-income or minority groups. The literature on residential segregation measurement, however, has not yet been considered a source of insights for the measurement of environmental inequalities. Here, we propose two segregation-based indices-the Environmental Dissimilarity gap index (Delta EDK) and the Environmental Centralization index (ECd)-and a randomization method to make robust environmental inequality assessments. In addition, to help policy-makers target local policies better, we developed an original approach to identify and map hotspots that have a large influence on environmental inequalities. These methods are applied in Grenoble, France, to study the distribution of green spaces and industrial risks between poor and non-poor households.
