Central banks and financial regulators play a critical role in steering the financial system toward climate objectives and fostering the development of sustainable finance markets. Since 2021, the Macro and Green Finance Lab (MGF Lab) at the National School of Development, Peking University, has been tracking sustainable finance policies issued by central banks and financial regulators in major economies and policy guidelines published by international organizations. Updated weekly, this policy tracker offers policymakers, financial practitioners, researchers, and the wider public an overview of evolving policy landscapes, key developments, and emerging global trends in sustainable finance.
