The Organisation for Economic Co-operation and Development (OECD) has published a report that tracks a variety of climate-related financial sector policies, assesses the degree to which financial flows align with climate goals, and charts the landscape of climate metrics used in the financial sector. The report seeks to support investors and policymakers by identifying untapped opportunities to transition financial flows.

Themed, ‘Different Policy Playbooks, Untapped Investment Opportunities,’ the 134-page Review on Aligning Finance with Climate Goals 2026 finds that the number and mix of climate-related financial sector policies has continued to expand. Between 2023 and 2025, their number grew by more than 25%, with transparency dominating the mix (78%), prudential measures on the rise (20%), and monetary policy tools remaining scarce (2%).

The report further finds that different countries tend to adopt different “policy playbooks,” attaching varying degrees of importance to disclosure requirements, voluntary transparency tools, stress tests, and other prudential tools. For instance, Africa and Asia-Pacific continue to lean more towards transparency, while Europe and North America display higher shares for climate-related prudential policies.

Climate alignment has increased for some financial flows and stocks, according to the report. For example, it highlights that low-carbon real-economy investments are increasingly outpacing fossil fuel investments. However, it emphasizes that there is no convergence of trends across asset classes as of yet.

The report finds that some regions are better than others at capturing opportunities of financing their climate transition through green corporate bond issuance. For example, green-labeled corporate bonds in Africa, Europe, and parts of Asia-Pacific outpace traditional corporate bonds issued by fossil fuel companies. At the same time, the opposite is true for other parts of Asia and the Americas. The report concludes that against the backdrop of the large volume of traditional corporate bond issuance to energy and industrial sectors, there are untapped opportunities to transition financial flows across geographies.

The report was released on 9 June, during the first week of the 2026 Bonn Climate Change Conference. [Publication: OECD Review on Aligning Finance with Climate Goals 2026: Different Policy Playbooks, Untapped Investment Opportunities] [Publication Landing Page]
