This chapter focuses on the democratic innovations of deliberative mini-publics by exploring the ways in which they can contribute to the democratisation of transnational and global governance. As international institutions like the European Union and global frameworks such as the Paris Climate Agreement are suffering a crisis of legitimacy, there is a need to further develop transnational democracy. This chapter provides the first systematic mapping of transnational mini-publics in the context of transnational and global governance. Data includes 19 mini-publics that are catalogued and analysed. Emerging trends include high participant learning, low direct policy, and moderate institutional and media impacts. The prospects, challenges and emerging research needs are discussed as well. ICTs, online methods and Artificial Intelligence will likely add new opportunities and lower the expenses of global deliberative mini-publics in the future.
