Ahead of the 2021 United Nations Climate Change Conference (COP26), this webinar will explore the role of nuclear energy in climate action and sustainable development by focusing on recent developments in Europe. The webinar will provide an overview of the ongoing policy dialogue taking place within the United National Economic Commission for Europe (UNECE) region on the role of nuclear energy in climate action and sustainable development and how it is being shaped by the global discourse on this topic and member states’ national policies towards nuclear energy. The webinar will also address ongoing developments related to the EU taxonomy of sustainable economic activities (within the context of the EU Taxonomy Climate Delegated Act) and implications of the inclusion (or exclusion) of nuclear energy in the taxonomy on nuclear projects both in the EU and worldwide. Given that the final disposal of high-level radioactive waste is a key challenge for the sustainability of nuclear energy, the webinar will take a closer look at the progress Finland has made in relation to its construction of the world’s first deep geological repository. Through this webinar, the Centre for International Law aims to contribute to the emerging regional discourse on the role of nuclear energy in climate action and sustainable development.
