The report analyzes the integration of methane abatement in sustainable finance taxonomies across five jurisdictions. It finds significant gaps in sectoral coverage, a tendency to prioritize usability over technical rigor, and a lack of specific, measurable criteria. To address these, the report provides a framework of best-practice measures for the energy, agriculture, waste, and wastewater sectors.

This executive summary outlines evidence-based criteria and best-practice measures to help policymakers and taxonomy developers integrate methane reduction into sustainable finance frameworks. It identifies four key sectors for mitigation—energy, agriculture, solid waste, and wastewater—and provides specific technical benchmarks, such as lifecycle GHG emission thresholds for bioenergy and leak detection and repair (LDAR) requirements. The goal is to increase the flow of capital toward cost-effective methane abatement, which currently falls short of the estimated USD 48 billion annual requirement through 2030.

The Climate Bonds’ Resilience Taxonomy (CBRT) is a classification system designed to help infrastructure issuers identify and certify investments that enhance climate resilience. It covers over 1,400 investments across seven themes, including health, agri-food, and energy systems. The taxonomy employs a tiered eligibility framework requiring a 'substantial contribution to resilience', 'no maladaptation risk', and 'Do No Significant Harm (DNSH)' to other sustainability goals. Investments are categorized as whitelisted (automatically aligned), subject to technical specifications (binary pass/fail checks), or requiring a process-based approach for flexible placeholders. The guide outlines two primary use cases: developing a project pipeline by filtering for material climate hazards and mapping existing projects to verify eligibility for thematic bonds. Currently in an interim phase, the CBRT is designed for interoperability with the EU Taxonomy, the MDB joint methodology, and the LAC Common Framework.

The report identifies a growing global landscape of over 60 sustainable finance taxonomies, noting high-level interoperability in classification structures and objectives but significant challenges at the granular criteria level. While development is accelerating, implementation remains in early stages, particularly in emerging markets and developing economies (EMDEs). The Taxonomy Roadmap Initiative, launched at COP29, aims to address these gaps through three pillars: identifying core economic activities, developing common technical approaches, and formulating transition finance guidelines. To support these goals, the initiative is launching a set of tools at COP30, including a Sustainable Finance Taxonomy Mapper and Principles for Taxonomy Interoperability.

The document outlines seven principles for the interoperability of sustainable finance taxonomies, aimed at facilitating international capital flows by enabling the comparison of taxonomies based on common principles or shared scientific foundations. Launched as part of the Roadmap for Advancing Interoperability and Comparability of Sustainable Finance Taxonomies, these principles target policy designers to improve usability and credibility across different stages of taxonomy maturity.

The document outlines seven principles for the design and implementation of sustainable finance taxonomies to facilitate cross-border capital flows. Launched as part of the 'Roadmap for Advancing Interoperability and Comparability of Sustainable Finance Taxonomies' initiative, these principles aim to help policymakers and developers create frameworks based on shared scientific bases and common design elements, while remaining aligned with local priorities and international best practices.

The document introduces the 'Principles for Taxonomy Interoperability' as part of the 'Taxonomies Roadmap Initiative' launched at COP29. It argues that while local taxonomies are essential for market development, 'interoperability'—the ability to compare taxonomies based on common principles or scientific baselines—is necessary for cross-border capital flows. The guide outlines seven principles covering design and implementation to improve the usability and credibility of sustainable finance taxonomies, particularly supporting the leadership of the Global South in alignment with COP30 goals.

The Principles for Taxonomy Interoperability, published by the Climate Bonds Initiative as part of the Taxonomy Roadmap Initiative, provide a framework to make diverse national and regional sustainable finance taxonomies comparable. The document argues that while local priorities necessitate different criteria, interoperability—based on common language, structures, and scientific baselines—is essential for scaling private climate finance. It outlines seven principles covering foundation, design, use cases, coverage, complexity, market signaling, and international collaboration. Additionally, it provides guidance on core design pillars such as sector structure (based on ISIC), common environmental objectives, and transition approaches (binary, traffic light, or merged).

The report outlines seven principles for taxonomy interoperability to facilitate cross-border capital flows for sustainable finance. It emphasizes the use of common terminology, scientific baselines, and collaborative international efforts to align diverse national taxonomies without requiring them to be identical.

As of Q3 2025, the cumulative volume of aligned GSS+ debt reached USD 6.5 trillion. Green bonds remain the dominant theme, accounting for 64% of aligned volume in Q3 2025, while sustainability-labelled debt is gaining momentum. Non-financial and financial corporates were the most prolific issuers in the quarter, and supranationals remain the largest historical source of cumulative aligned volume.

The report identifies a conservative USD 4.4 trillion pipeline of creditworthy sustainable bonds from 12 climate-leader countries through 2035. It argues that global megatrends—such as electrification, urbanisation, and the rise of AI—will further accelerate this pipeline beyond current projections. The document also outlines policy levers, including taxonomies and monetary policy, that governments can use to channel capital into mitigation and resilience projects.

The green bond market began in 2007 with the European Investment Bank and uses specific principles to ensure capital supports climate-aligned causes. As of June 2022, the Climate Bonds Initiative's Green Bond Database recorded over 10,000 green bonds with cumulative volumes of USD 1.9 trillion, though total issuance is higher as the database only includes Paris-aligned bonds meeting specific reporting standards.

The report examines the decarbonisation of Brazil's cement and steel sectors, highlighting the role of low-carbon hydrogen, carbon capture and storage, and green finance in achieving net-zero emissions by 2050.

The report analyzes the decarbonization pathways for Brazil's cement and steel sectors, highlighting the role of emerging technologies like low-carbon hydrogen and carbon capture, the impact of international regulations like the EU's CBAM, and the availability of green financing instruments to support the industrial transition.

The report provides a comprehensive overview of Brazil's sustainable debt market (VSS+) as of June 30, 2025, highlighting the dominance of green bonds and the role of non-financial corporations. It details the regulatory landscape, including the development of the Brazilian Sustainable Taxonomy (TSB), and identifies strategic investment opportunities across sectors such as agriculture, energy, and sanitation.

The report argues that rapid methane abatement is a priority for transition finance due to its immediate impact on limiting global warming to 1.5°C. It analyzes the current financing landscape, noting a significant gap between the USD 9.6bn in private methane finance (2021/2022) and the estimated USD 48bn to USD 100bn required annually by 2030. Through case studies of 20 corporates, the report finds that while oil and gas firms generally integrate methane abatement into short-term strategies, agrifood firms struggle with supply chain tracking and specific targets. To address this, the report promotes the use of Use of Proceeds (UOP) and sustainability-linked instruments guided by Climate Bonds and Methane Finance Working Group (MFWG) criteria to ensure investments contribute to decarbonization without locking in high-carbon assets.

The report examines the financing gap for methane abatement, noting that while significant investment opportunities exist, current funding is limited compared to the estimated $48 billion annual need by 2030. It analyzes the transition plans of 20 major companies, finding that oil and gas firms are more advanced in integrating methane targets than agri-food companies. The document promotes the use of Use of Proceeds (UoP) and Sustainability-Linked Bonds (SLB), supported by new standards from the Climate Bonds Initiative (CBI) and the Methane Finance Working Group (MFWG), to avoid carbon lock-in and ensure scientific alignment with the 1.5°C goal.

The report outlines a framework for sovereign transition planning based on five pillars: robust targets, a whole-of-government approach, green public financial management (PFM), a diverse policy mix, and transparency. It argues that integrating climate considerations into core budgetary processes (green PFM) is essential for coordinating action across all government departments. To address fiscal constraints and debt overhang, the report suggests alternative financing mechanisms, including carving out transition spending from deficit limits, utilizing GSS+ and sustainability-linked bonds, leveraging national development banks and sovereign wealth funds, and employing central bank monetary tools such as green asset purchases and adjusted collateral frameworks.

The report outlines a framework for credible sovereign transition planning based on five elements: robust targets, a 'whole-of-government' approach, green public financial management, integrated policy tools, and transparency. It addresses the challenge of 'debt overhang' in both developed and emerging markets, suggesting alternatives such as excluding transition spending from deficit calculations and utilizing GSS+ bonds. The document also examines the roles of national development banks, sovereign wealth funds, and central banks in mobilizing private capital and providing low-cost financing for climate action.

Methane abatement is critical for near-term climate action, requiring a 45% reduction in global emissions by 2030. The report highlights that the energy sector has the highest technical abatement potential, while agriculture is dominated by behavioural change opportunities. It identifies five national sector archetypes—China's coal, India's smallholder agriculture, Brazil's livestock, Indonesia's waste, and O&G exporters—to provide scalable policy lessons. Significant financing gaps exist, with only USD 13.7bn tracked in 2021/22 against an estimated annual need of USD 48bn. The report advocates for methane-specific targets in NDCs, the use of satellite monitoring to close data gaps, and the implementation of import standards and carbon pricing to drive global supply chain reductions.
