Having realised that its traditional mode of coordinating-essentially issuing regulation-no longer commands sufficient political support, the European Union (EU) has turned to what are increasingly referred to as ‘new’ modes of governance, which rely upon different actors working together in relatively non-hierarchical networks. This book provides the first extended account of how effective they are at addressing ‘wicked’ policy problems which simultaneously demandgreater levels of horizontal and vertical coordination. Taking, as an example, the thirty year struggle to integrate environmental thinking into all areas and levels of EU policy making, it offers a stark reminder that networked governance is not and is unlikely ever to be a panacea. In doing so, itstrips away some of the rhetorical claims made about the novelty and appeal of ‘new’ modes, to reveal a much more sober and realistic appraisal of their coordinating potential.
