With the advent of the 2030 Agenda, the principle of policy coherence has now been extended to cover the whole scope of sustainable development. PCSD,or‘policy coherence for sustainable development’,has thus become a reality reflected in the ‘Systemic Issues’ section of Sustainable Development Goal 17 (SDG17) on ‘Strengthening the Means of Implementation and Revitalizing the Global Partnership’. Yet for those familiar with the practice of PCD, the challenge of this logical but much broader concept is immense. Recent research has demonstrated the multiple linkages that exist across the Sustainable Development Goals (SDGs) and the effort in terms of integrated policy making that the 2030 Agenda will require. How this might be tackled, and what useful lessons can be gleaned from past practice in promoting policy coherence to support this effort, are the subjects of this paper.
