The International Law of Environmental Impact Assessment

Neil Craik examines the structure and role of international environmental impact assessments.

Neil Craik examines the structure and role of international rules requiring States to undertake environmental impact assessments where their proposed activities may have adverse environmental consequences for other States or for global environmental resources, such as biodiversity or climate change.The central idea animating environmental impact assessment (EIA) is that decisions affecting the environment should be made through a comprehensive evaluation of predicted impacts. Notwithstanding their evaluative mandate, EIA processes do not impose specific environmental standards, but rely on the creation of open, participatory and information rich decision-making settings to bring about environmentally benign outcomes. In light of this tension between process and substance, Neil Craik assesses whether EIA, as a method of implementing international environmental law, is a sound policy strategy, and how international EIA commitments structure transnational interactions in order to influence decisions affecting the international environment. Through a comprehensive description of international EIA commitments and their implementation with domestic and transnational governance structures, and drawing on specific examples of transnational EIA processes, the author examines how international EIA commitments can facilitate interest coordination, and provide opportunities for persuasion and for the internalisation of international environmental norms.
