This chapter examines the climate club concept as a novel framework for enhancing global climate governance through focused and cooperative action among willing nations. By adopting a minilateral approach, climate clubs aim to circumvent the inefficiencies of multilateral negotiations, leveraging market-based mechanisms to encourage ambitious emissions reductions. The European Green Deal is a compelling example of how targeted policies and economic incentives can drive regional and global climate progress. However, the approach faces significant challenges, particularly regarding equity and inclusivity. Critics highlight potential deviations from the principle of Common but Differentiated Responsibilities and Respective Capabilities, raising concerns about marginalizing less developed countries. Practical challenges, such as aligning diverse interests, ensuring compliance, and managing policy coordination, also pose hurdles. Despite these issues, the climate club concept offers a strategic and pragmatic pathway to global climate cooperation. By addressing these challenges and aligning with the goals of the Paris Agreement, climate clubs have the potential to serve as effective and legitimate mechanisms for accelerating global climate action.
