Advancing Sustainable Finance Taxonomies and Interoperability Taxonomy Roadmap Initiative Progress Report

The Taxonomy Roadmap Initiative Progress Report (November 2025) details the global expansion of sustainable finance taxonomies, noting that over 60 are currently in use or development. While high-level interoperability is increasing—with 64% using ISIC-based sector structures and 100% of published taxonomies covering climate mitigation—granular alignment remains difficult. The report highlights that implementation is still in early stages in emerging markets and announces the launch of new tools at COP30, including the Sustainable Finance Taxonomy Mapper and Principles for Taxonomy Interoperability, to catalyze cross-border capital flows.

• As of September 2025, there is a significant increase in the development of sustainable finance taxonomies globally, with over 60 taxonomies either in use or under development. This growth is most prominent in Europe and Central Asia (46%), followed by East Asia and the Pacific (23%), Sub-Saharan Africa (13%), and Latin America and the Caribbean (12%).
• High-level interoperability is evident across many taxonomies, particularly in their organizing structures and objectives. Approximately 64% of the 53 published or in-development taxonomies use a sector structure based on national classifications derived from the International Standard Industrial Classification of All Economic Activities (ISIC). Additionally, 100% of jurisdictions with published taxonomies include climate mitigation within their scope.
• While high-level alignment exists, interoperability at the granular criteria level remains a significant challenge. The report notes a lack of available data to compare taxonomies at this level, and evidence from the Multi-jurisdictional Common Ground Taxonomy (M-CGT) highlights the difficulty of comparing frameworks developed with different research and pathways.
• The implementation and practical application of taxonomies are still in early stages, especially in emerging markets and developing economies (EMDEs). Mandatory applications are rare, and there is a limited amount of data to systematically evaluate usage, though case studies suggest a need to prioritize and standardize low-complexity use cases.
• The Taxonomy Roadmap Initiative, launched at COP29, is introducing four key deliverables at COP30 to facilitate global interoperability: the Progress Report, the Principles for Taxonomy Interoperability, the Sustainable Finance Taxonomy Mapper (a digital tool for comparing taxonomies), and a dedicated website for coordination.
• Brazil's Ministry of Finance is developing a national Sustainable Taxonomy that includes a first-of-its-kind race-oriented criterion to reduce racial and gender inequality, aligned with a national proposal for SDG 18. Brazil is also developing objectives for biodiversity and the circular economy, and is creating a verification ecosystem for taxonomy-related reports through Standard 14.030-4.
• The Taxonomy Roadmap is structured around three core pillars: identifying a common core set of economic activities, developing common technical approaches for alignment with principles and criteria, and formulating common approaches to financing the transition.
• Regional frameworks are playing a key role in guiding national developments. Examples include the ASEAN Taxonomy for Sustainable Finance, the LAC Common Framework of Sustainable Finance Taxonomies, the AMF-UMOA classification system in West Africa, and the Regional Green Finance Taxonomy by CCSABO in Central America.
