This book examines how the EU and international law frameworks impact the EU’s ability to act normatively in its external action in the area of fisheries. The EU, a major fishing power, portrays itself as a normative actor and a champion of sustainable fishing. The volume reconceptualises the Normative Power Europe narrative by identifying three interrelated elements – universality, use of instruments, and legitimacy – as the key criteria against which to evaluate the normativity of the EU’s conduct. The universality element examines the level of international acceptance of the stated aims of EU action; the use of instruments element examines the EU’s participation limitations in relevant international institutions and the means (persuasion as opposed to coercion) through which it acts; and the legitimacy element examines the substance of the EU’s action in terms of legality, protection of common or self-interests, and coherence and consistency. The volume is aimed at academics and practitioners alike working in the area of fisheries globally but also on the EU’s external action more generally.
