Abstract
This lecture, delivered at the ceremony for the inaugural Global Inequality Research Award at Sciences Po in Paris, provides a trajectory of the author’s work on inequality and the environment that was recognized by the award. Thirty years ago, many economists and environmentalists saw inequality as a non-issue. Today there is widespread recognition of its importance. The lecture reviews how inequalities in the distribution of wealth and power affect both the magnitude and incidence of environmental harms and discusses some of the synergies between policies to reduce inequality and to improve environmental quality.
