Translation of the principle of sustainable development into policy and practice, and the evaluation of the outcomes of these strategic interventions, are some of the most pressing challenges facing policymakers in Europe and beyond. The chapters in this book contribute to the debate surrounding these challenges. By exploring the conceptual and methodological issues relating to the evaluation of sustainable development and analysing European practice and experience, this work provides a coherent and integrated contribution to our understanding of these issues. With contributions from a distinguished international group of authors, this book will be of interest to researchers, policy analysts and practitioners in the area of impact assessment and sustainable development.
