The Climate Bonds Initiative (CBI) has developed an Equivalence Methodology for Climate Mitigation to operationalise interoperability between various global green finance taxonomies. The methodology provides a technical framework to assess whether externally developed criteria for economic activities and decarbonisation measures are equivalent to CBI's science-based standards, allowing them to be incorporated into the expanded Climate Bonds Taxonomy and Certification Scheme.

The Climate Bonds’ Resilience Taxonomy (CBRT) is a classification system designed to help corporate infrastructure issuers identify and verify investments that contribute to climate adaptation and resilience. Currently in an interim phase with draft screening criteria, the CBRT covers over 1,400 investments across seven resilience themes, providing a framework for determining eligibility, alignment, and eligible costs for thematic bonds.

This guide presents the 'Principles for Taxonomy Interoperability,' developed under the 'Roadmap for Promoting Interoperability and Comparability of Sustainable Finance Taxonomies' initiative. Launched at COP29 in 2024 by the Central Bank of Azerbaijan (CBAR), the initiative seeks to establish a unified taxonomy and technical guidelines for transition activities to facilitate cross-border capital flows by ensuring different sustainable finance taxonomies can be compared based on common principles or scientific baselines.

The 'Principles for Taxonomy Interoperability' report, published by the Climate Bonds Initiative in November 2025, provides a framework for sustainable finance taxonomy developers and policymakers to ensure that national and regional taxonomies are comparable and interoperable. Launched under the Taxonomy Roadmap Initiative at COP29, the document outlines seven high-level principles designed to reduce barriers to cross-border capital flows by establishing common design features, terminology, and implementation strategies while respecting jurisdictional priorities.

This policy brief by the Climate Policy Initiative argues that Indonesia can accelerate methane abatement by embedding specific technical screening criteria (TSC) for methane-reducing activities into Version 3 of its national sustainable finance taxonomy (TKBI). The document highlights a significant funding gap for methane mitigation in the agriculture and waste sectors and suggests that granular taxonomy definitions are essential to make these projects bankable for private investors.

The 'Criteria for Certification against the Climate Bonds Resilience Taxonomy' provides interim guidelines for certifying climate resilience investments listed in the Climate Bonds Resilience Taxonomy (CBRT). It establishes a three-part requirement for certification: demonstrating a substantial contribution to resilience, managing maladaptation risks, and ensuring no significant harm to climate mitigation objectives. The document details the assessment processes for different investment types, including adapted activities, adapting measures, enabling activities, and enabling measures.

The Hong Kong Sustainable Debt Market Briefing 2024 analyzes the performance of sustainable debt in Hong Kong through the end of 2024, highlighting a decline in locally originated debt alongside a significant increase in international GSS+ bond issuance and the launch of the Hong Kong Taxonomy.

This supplementary guide from the Climate Bonds Initiative establishes interim process criteria for certifying climate resilience investments listed in the Climate Bonds Resilience Taxonomy (CBRT) that currently lack specific sector criteria. It defines the requirements for Use-of-Proceeds and Asset Certification, focusing on substantial contributions to resilience, management of maladaptation risks, and ensuring no significant harm to climate mitigation objectives.

The International Platform Sustainable Finance (IPSF) Common Ground Taxonomy (CGT) Instruction Report (November 2024) provides a technical comparison between the sustainable finance taxonomies of the European Union (EU) and China. The report identifies areas of commonality and divergence to enhance the interoperability of green finance standards, aiming to reduce trans-boundary costs for green investments and scale up international green capital mobilization.

This document provides the technical annexes for a report on climate finance needs for agrifood systems. It details a taxonomy developed by the Climate Policy Initiative (CPI) and the Food and Agriculture Organization (FAO), and describes two methodologies used to estimate finance needs: a top-down approach based on a literature review of third-party reports and a bottom-up approach based on the analysis of Nationally Determined Contributions (NDCs).

The Hong Kong Green Market Briefing 2023, published by the Climate Bonds Initiative, provides a comprehensive analysis of the sustainable debt market in Hong Kong as of December 31, 2023. The report highlights a significant surge in aligned GSS+ debt originating from the HKSAR, driven primarily by government green bond issuance, and examines the role of the Hong Kong Stock Exchange (HKEX) and the Common Ground Taxonomy (CGT) in connecting Chinese and international capital.

This case study analyzes the sensitivity of sustainability classifications for rural credit in Brazil, comparing five different taxonomies and initiatives applied to data from the BCB's SICOR system between July 2015 and June 2023.

The Climate Bonds Resilience Taxonomy (CBRT) Methodology provides a science-based classification system and interim screening criteria to identify and scale investments that contribute to climate adaptation and resilience. It establishes a framework to distinguish between different types of resilience investments and ensures they provide a measurable reduction in vulnerability without causing maladaptation or significant harm to other sustainability goals.

This report presents design recommendations from an Independent Technical Advisory Group (ITAG) for the development of a Sustainable Finance Taxonomy for Aotearoa New Zealand. The proposed framework aims to mobilise capital toward a low-emissions, Paris-aligned future while restoring nature and upholding indigenous rights, with a strong emphasis on interoperability with the Australian taxonomy and the integration of iwi/Māori knowledge.

This report provides a technical comparison between the Colombian Green Taxonomy and the EU Taxonomy as of June 2023. It evaluates the alignment of Technical Screening Criteria (TSC), Do No Significant Harm (DNSH) principles, and Minimum Safeguards (MS) across various economic sectors to facilitate cross-border financial flows and reduce research costs for international investors.

The China Sustainable Debt State of the Market Report 2022, published by the Climate Bonds Initiative, CCDC Research, and CIB Research, analyzes the growth and composition of China's green, social, sustainability, sustainability-linked (SLB), and transition bond markets (GSS+) through the end of 2022.

This white paper by the Climate Bonds Initiative presents a blueprint for a climate resilience classification framework designed to mobilize capital market investment into climate-resilient assets, activities, and entities. It proposes a systematic approach to identify eligible investments based on their 'Substantial Contribution' to resilience while avoiding maladaptation and significant harm to other sustainability goals.

This report by the Climate Bonds Initiative analyzes the alignment of green, social, and sustainability bonds priced in the first nine months of 2022 with its database standards. While most issuance meets these criteria, a significant portion of labelled debt is excluded due to insufficient disclosure or a lack of ambition in the Use of Proceeds (UoP).

The Hong Kong Green and Sustainable Debt Market Briefing 2021, published by the Climate Bonds Initiative, analyzes the growth and composition of the GSS+ (green, social, sustainability, transition, and sustainability-linked) debt market in Hong Kong for the year 2021.
