The adoption of the Sustainable Development Goals (SDGs) by the UN, in 2015, established a clear global mandate for greater integrated policymaking, but there has been little consensus on how to achieve them. The COVID-19 pandemic amplified the role of policy capacity in mounting this kind of integrated policy response; however, the relationship between pre- and post-pandemic SDG efforts remains largely unexplored. In this article, we seek to address this gap through a conceptual analysis of policy integration and the capacities necessary for its application to the current SDG situation. Building on the literature on policy design, we define policy integration as the process of effectively reconciling policy goals and policy instruments and we offer a typology of policy integration efforts based on the degree of goal and instrument consistency including: policy harmonization, mainstreaming, coordination, and institutionalization. These forms of policy integration dictate the types of strategies that governments need to adopt in order to arrive at a more coherent policy mix. Following the dimensions of policy capacity by Wu et al. (2015), policy capacities are identified that are critical to ensuring successful integration. This information, thus, contributes to both academic- and policy-related debates on policy integration, by advancing conceptual clarity on the different, and sometimes, diverging concepts used in the field.
