Climate Governance: Comparing Centralized and Decentralized Approaches

Climate governance is entering a period of turbulence, with policy reversals in some democracies and rapid expansions elsewhere. This paper compares how centralized, decentralized (federal), and polycentric/hybrid governance designs shape mitigation and adaptation outcomes. Using a qualitative comparative approach across China, the United States, Canada, Türkiye, Norway, and Saudi Arabia, assessing policy ambition, legal instruments, implementation capacity, subnational authority, stakeholder participation, finance mobilization, and equity considerations. A qualitative comparative approach is applied across six country cases - China, the United States, Canada, Türkiye, Norway, and Saudi Arabia - evaluating policy ambition, legal instruments, implementation capacity, subnational authority, stakeholder participation, finance mobilization, and equity considerations. Insights are then extended to the Central Asian context, where climate governance remains predominantly centralized, shaped by Soviet-era institutional legacies, uneven local capacity, and constrained civic participation. The analysis demonstrates that no model is universally superior; the most effective arrangements combine top-down coherence with bottom-up experimentation and social legitimacy. Norway’s polycentric governance model and Türkiye’s hybrid approach illustrate how localized climate planning can be integrated within broader national frameworks. For Central Asia, pragmatic hybrid pathways are recommended that align national targets and financing with empowered regional pilots, transparent monitoring, and inclusive engagement. These context-sensitive combinations offer the best prospects for durable emissions reductions, climate resilience, and just transition outcomes in the region.
