The book assesses the EU performance in the broader UN setting after the Lisbon Treaty. Distinguished scholars with expertise in EU-UN relations use a comprehensive analytical framework of performance to examine various aspects of the complex EU engagement in UN politics. Performance goes beyond the achievement of agreed-upon objectives and engulfs the underlying, intra-organizational, agreement-reaching processes. The contributors examine the output of the intra-EU policy-making process and its impact within the UN setting. They cover thematic areas of special importance for the EU such as environment, human rights, disarmament and peacekeeping operations as well as special UN bodies and forums where the EU is particularly active, such as the UN General Assembly and its main Committees, the International Labour Organisation, UNESCO and the Non-Proliferation Review Conferences.--
