In a globalized and interconnected world, no single state can independently address global challenges, as they require collective action on a global scale. The current global approach to global challenges often proves to be inefficient due to limitations in the existing structure of global governance, a lack of accountability, and a democratic deficit. Cosmopolitan theories and cosmopolitan democracy offer themselves as both moral and practical political solutions for addressing supranational challenges, including proposals for reforming global governance institutions.
Initiatives for cosmopolitan reform also refer to the United Nations as the sole universal international organization. One such reform proposal involves establishing a parliamentary assembly within the UN system to address the democratic deficit. This master's thesis contributes to the study of cosmopolitanism by presenting the historical development of cosmopolitan theories and connecting them with the concept of global governance as a potential solution to address the democratic deficit within global governance structures. It further analyses and substantiates the proposal for establishing a UN Parliamentary Assembly as a practical cosmopolitan concept.
