This article offers a survey of the legal and regulatory issues associated with carbon capture and storage (CCS) projects in the eight Arctic states. It comprises five parts, offering some introductory notes, a very brief insight into CCS, assessing each jurisdiction in terms of sources and sequestration geology and current or proposed CCS projects, providing an account of relevant rules, and finishing with brief conclusions. Because CCS is a costly technology, and, moreover, can only be implemented where there are large point-source final emitters and favorable storage geology, CCS projects in Arctic states will cluster around a limited number of industrial locations which will include oil and gas production facilities and large mining and mineral processing facilities that also have suitable storage targets close at hand. In addition to suitable emissions sources and geological targets and appropriate economic incentives, proponents of CCS projects and the public also need the assurance of an appropriate legal and regulatory regime. Such regimes have been slow to develop in Arctic states, although adoption of the European Union’s CCS Directive and the need for its transposition in the EU Member States and possibly in the EEA states has arguably created some momentum
