This report examines the role of financial centres as platforms for operationalizing NDC-aligned transition finance. Positioned at the intersection of policy and markets, financial centres can convene regulators, financial institutions, investors, and the real economy to align capital flows with national climate priorities. They help localize global frameworks, reduce fragmentation across standards, and translate high-level commitments into practical tools, data, and incentives that support investment. Drawing on peer learning under the Financial Centres for Sustainability (FC4S) network and workshops held in Brazil, Mexico, and Singapore, the report distils practical lessons on transition finance across the five pillars of the G20 Transition Finance Framework.
