This chapter assesses the ways in which different iterations of the principle of equity in international law may usefully inform environmental peacebuilding frameworks and strategies. It charts the distinct conceptual meaning and significance that the principle has come to possess in international environmental law before exploring how some of its practical legal translations may assist environmental peacebuilding. Attention is paid to the role equity can play in the management of shared resources and its attendant peacebuilding benefits, both in its substantive dimension, through the principle of equitable and sustainable utilization, as well as through its procedural dimension, through the role of participatory decision-making in resource management. The chapter also considers how the principle of ‘common but differentiated responsibilities’ may offer an equitable alternative to the limitations that classic understandings of state responsibility present for effective environmental restoration and reparation in post-conflict settings.
