In a world marked by climate shocks, technological disruption, deepening inequality, and fractured geopolitics, the credibility of global governance hinges not just on bold ideas, but on their implementation. Yet a persistent gap remains between evidence and action. How can think tanks and civil society actors step up—not just as sources of policy insight, but as force multipliers for accountability, ambition, and execution?  

This session brings together leading think tanks from the G7 (Canada), G20 (South Africa), and BRICS (Brazil) CoP 2025 to forge research-driven, actionable pathways for enhancing multilateral cooperation. Building on T7 Canada’s recent Communique, the discussion will highlight key priorities set by G7 Canada, and propose practical strategies for T20 South Africa to advance synergies and overcome implementation barriers, and explore divergences if any. The session will also unveil the T30 initiative—a bold new effort to accelerate climate action by uniting think tanks from the 30 countries most pivotal to shaping the future of global climate politics.
