Environmental policymaking has become an experimental field for new modes of governance. This timely book focuses on three prominent characteristics of new governance arrangements: the broad participation of non-state actors, the attempt to improve vertical and horizontal coordination, and the effort to integrate different types of expertise in an effective and democratically accountable way. Building on the analytical perspectives of legitimacy and effectiveness, which are seen as genuine acid test criteria for new governance, this book provides a critical assessment of current practices of participation, coordination and evidence-based policymaking in various case studies of environmental governance, in particular in the fields of biodiversity, climate and forest policy. The book provides insights from selected governance processes that go beyond consultancy-style best-practice examples but are embedded in a solid conceptual and theoretical discussion that will be invaluable to policymakers. It will also prove essential for scholars interested in environmental politics; policy studies; public policy; public administration; European politics; as well as science and technology studies.
