Princípios de Interoperabilidade Taxonômica

The 'Princípios de Interoperabilidade Taxonômica' report, published by the Climate Bonds Initiative in November 2025, provides a high-level framework to help sustainable finance taxonomy developers and policymakers increase the comparability and cross-border flow of capital. It introduces seven principles designed to align national and regional taxonomies through common languages, scientific baselines, and collaborative international efforts, supporting the broader 'Taxonomy Roadmap Initiative' launched at COP29.

• The report defines 'interoperability' as the capacity to compare sustainable finance taxonomies based on common principles or a scientific baseline, such as the Paris Agreement. Interoperable taxonomies are not identical but share common languages, structures, and objectives to enable cross-border understanding and capital flow.
• The document outlines seven core principles for taxonomy interoperability: 1) basing taxonomies on jurisdictional priorities and G20 best practices; 2) using common terminology and resources (e.g., ISIC sector classifications); 3) defining clear use cases and prioritizing SMEs; 4) ensuring regular reviews and expanding coverage to high-impact national activities; 5) reducing complexity via science-based criteria; 6) promoting market adoption through user support and pilots; and 7) participating in international collaborative efforts.
• To improve technical interoperability, the report recommends adopting six common environmental objectives: climate change mitigation, climate change adaptation, biodiversity protection, sustainable use of water and marine resources, pollution control, and circular economy.
• The report emphasizes the importance of 'pass/fail' (binary) technical criteria over principle-based language (such as 'minimize' or 'reduce') to reduce subjectivity and facilitate cross-border alignment.
• The document identifies three main transition methodologies used by taxonomies to encourage the shift toward net-zero: binary methodologies (e.g., EU), 'traffic light' approaches (e.g., ASEAN), and combined approaches (e.g., Australia).
• The 'Taxonomy Roadmap Initiative' aims to increase interoperability through three pillars: identifying a common core set of economic activities, developing common technical methodologies for alignment, and formulating common methodologies for financing the transition.
