This report presents a consensus position in the form of a Collective Opinion of the Radioactive Waste Management Committee (RWMC) of the OECD Nuclear Energy Agency. It addresses the strategy for the final disposal of long-lived radioactive wastes seen from an environmental and ethical perspective, including considerations of equity and fairness within and between generations. This Collective Opinion, by professionals having responsibilities at a national level in the field of radioactive waste management, is intended to contribute to an informed and constructive debate on this subject. Of particular importance in these discussions was the participation of the OECD Environment Directorate, and of independent experts from academic and environmental policy centres. The full proceedings of this workshop have been published by the OECD.
