The chapter analyses the potential of minilateralism as an alternative governance structure for climate cooperation, which can address the limitations of traditional multilateral approaches. Minilateralism offers a pragmatic and flexible platform for focused, efficient, and region-specific climate action, allowing smaller groups of like-minded countries to lead innovative mitigation efforts. These initiatives complement multilateral frameworks by serving as experimental hubs for climate solutions. The chapter highlights the necessity of aligning minilateral efforts with existing agreements, such as the Paris Agreement, to ensure coherence in global climate governance. However, challenges such as inclusivity, legitimacy, and the risk of duplicating efforts must be addressed to maximize effectiveness. Ensuring meaningful participation from less developed nations and maintaining alignment with broader international objectives are vital to the success of minilateral initiatives. As the global climate landscape evolves, refining the minilateral approach to remain responsive and inclusive will be essential in advancing international climate action.
