Implementing the Sustainable Development Goals (SDGs) as an integrated set represents a major challenge for all governments. Policy coherence for sustainable development (PCSD) provides a solution to overcoming institutional silos and fragmented action. Experience shows that the ability to implement coherent policies is dependent on the institutional mechanisms used by governments to manage and co-ordinate policy. This chapter highlights institutional mechanisms for enhancing PCSD in light of good emerging practices in eight key areas: 1) Commitment and leadership, 2) Long-term vision, 3) Policy Integration, 4) Coordination, 5) Regional and local involvement, 6) Stakeholder engagement, 7) Policy impacts, and 8) Monitoring and reporting. It provides examples of recent institutional practices in 30 OECD countries, which have presented Voluntary National Reviews (VNRs) to the UN High Level Political Forum (HLPF).
