This chapter evaluates the legality of the climate club scheme, focusing on its alignment with the Paris Agreement and WTO norms. Through an analysis of Article 6 of the Paris Agreement, the chapter underscores how the club scheme complements and amplifies international climate governance, emphasizing its potential to foster heightened ambition and cooperation among countries. The Climate Club Initiative introduced at COP 28 exemplifies the practical application of this framework, highlighting its role in industrial decarbonization and advancing global climate goals. The chapter also addresses the compatibility of climate club linkages of extra carbon tariffs, import requirements leading to bans or quotas for high carbon emitted products, or surrender of emission allowance certificates for certain imports’ implications on WTO norms. The examination of the schedule of concessions, tariff deconsolidation, and the general elimination of quantitative restrictions has highlighted the intricate legal considerations involved in reconciling climate-related trade instruments with WTO law. The climate club scheme mitigates potential trade disputes and fosters a global market for green goods by proposing shared standards, carbon pricing mechanisms, and mutual recognition of emissions allowances. The integration of environmental and trade policies, leveraging legal flexibilities and multilateral negotiations, emerges as key to aligning climate action with sustainable trade practices. With dual legitimacy under the Paris Agreement and WTO law, the climate club framework offers an innovative and cooperative model for addressing the multifaceted challenges of climate change. Its evolution will be pivotal in advancing international climate governance and achieving the ambitious goals set by the Paris Agreement.
