This report from the SNS Democracy Council provides a thorough assessment of whether the current system of global governance is fit for purpose. Do current international organizations hold the power required to develop, implement, and enforce global policies? Do these institutions wield this power with sufficient effectiveness to reduce transboundary problems? And do they possess legitimacy as governing bodies in the eyes of citizens and elites? This report explores these themes in a comparative perspective, mapping and analyzing patterns across a broad range of international organizations in areas such as development, finance, health, human rights, security, and trade. As an illustration, the report also offers an in-depth analysis of power, effectiveness, and legitimacy in respect of global climate governance.Security and Global AffairsInstitutions, Decisions and Collective Behaviou
