This chapter sets out the logic of the practical pursuit of global justice through global democratization. The theory rests on the concept of formative agents of justice, who shape what justice should mean in specific contexts, and how it should be sought. The chapter analyses formative agents’ role in bridging the gap between democracy and justice, thereby situating this book’s contribution within existing debates on international ethics, global justice, global governance, and deliberative democracy, before outlining the ways deliberative democracy can promote global justice. This approach meets challenges arising from the irreducible disagreement over the content of justice in both theory and practice, and from the need to identify who exactly should be responsible for the advancement of justice. The theoretical arguments of the book will be informed by and applied to the process that yielded the Sustainable Development Goals, and to climate governance inasmuch as it takes on climate justice. These two cases are introduced, along with a discussion of the kinds of justice they promote, ignore, and obstruct. Chapter 1 concludes with a brief overview of the remaining chapters.

States and international organizations are central to global governance, and are significant formative agents of justice (and injustice), in advancing, sifting, or undermining principles. Despite their formal authority, states and international organizations cannot be relied upon to promote global justice. States in practice often veil their material self-interest in the language of justice. International organizations too can promote their own interest, as well as adhering rigidly to dominant discourses such as neoliberalism that restrict the kind of justice they can advance. Thus states and international organizations should primarily act as effectors of global justice whose task is to ensure the outcomes determined in more extensive deliberation are implemented. Some of their problematic formative agency aspects can be ameliorated by deliberative democratic means. The Open Working Group that finalized the content of the Sustainable Development Goals is indicative of the possibilities here, as it embodied novel deliberative features that curbed polarization, overcame impasse, and facilitated common-interest justifications. Engagements with civil society of the kind now glimpsed in global climate governance can open international organizations to deliberating competing conceptions of justice. This chapter concludes by showing how states and international organizations might expand their deliberative engagements.
