This evaluation study provides an in-depth look at the efforts to promote intra-governmental policy coherence for development that were made by the European Member States and Institutions since the late 1990s. A variety of institutional mechanisms have been put in place in the EU, which this study groups as explicit policy statements, institutional coordination mechanisms, and knowledge input & assessment mechanisms. Case studies on Finland, France, Germany, Spain, Sweden, the European Commission and the European Parliament provide more detailed descriptions of current practices. On the basis of the evidence that was collected, the evaluation study concludes that these efforts are as yet somewhat experimental and questions whether EU member states and institutions really possess the political will to see that policy coherence for development is maintained over the longer term. The report concludes by proposing a set of possible guidelines for mechanisms to promote PCD which builds on the notion of the PCD System developed during the study and brings out various steps required to address the weaknesses and obstacles that were identified.
