Since Anu Bradford’s groundbreaking book on the Brussels Effect there is a vastly evolving literature on the EU as a global regulatory actor as well as the global reach of EU law. This edited collection connects to this debate.Yet, it shifts the focus from the currently predominant public law focus to investigating European and EU private law and to connecting to literature and research on transnational law. To that end, it proceeds first conceptually by introducing and giving shape to the notion of a “European Transnational Private Law” through four conceptual contributions by the editors. Secondly, it focuses on several sectors (finance, taxation, investment, consumer law, labour law) and topics (climate litigation, global value chains, non-discrimination) to trace sector-specifically the role of EU private law in relation to transnational legal ordering.
