This briefing by the International Institute for Sustainable Development (IISD) argues that the commitment made at COP 28 to transition away from fossil fuels is currently failing, with production plans exceeding 1.5°C limits. It identifies COP 30 in Belém as a critical juncture for governments to align financial flows, increase the ambition of Nationally Determined Contributions (NDCs), and operationalize the Just Transition Work Programme (JTWP).

This report analyzes 32 Air Service Agreements (ASAs) among COFFIS member states to identify legal pathways for implementing aviation fuel taxes to support climate targets and fuel efficiency.

This briefing describes the Global Goal on Adaptation (GGA), an international framework established under the 2015 Paris Agreement to monitor and evaluate progress on climate adaptation. It details the development of approximately 100 draft indicators to be agreed upon at COP30 in Belém, which aim to move adaptation targets from broad pledges to quantifiable metrics. The document highlights the critical underfinancing of adaptation compared to mitigation and the potential for high returns on investment in resilience measures.

This policy brief by the African Future Policies Hub analyzes the implications of the July 2025 International Court of Justice (ICJ) Advisory Opinion on the Obligations of States in Respect of Climate Change. The document argues that the ruling provides a legal and moral foundation to demand scaled-up climate finance, emphasizing the principles of Common but Differentiated Responsibilities and Respective Capabilities (CBDR-RC) and the necessity of reparations. It specifically links the ruling to the Baku to Belém (B2B) Roadmap and the financing of the third generation of Nationally Determined Contributions (NDCs) leading up to COP30.

This issue note by the Center for International Environmental Law (CIEL) argues that the United Nations Framework Convention on Climate Change (UNFCCC) is paralyzed by its reliance on consensus-based decision-making. The report contends that this model allows a small minority of states to block ambitious climate action and proposes transitioning to a qualified majority voting system to accelerate progress and fulfill legal obligations to cooperate on climate change.

This report, published by the Center for International Environmental Law (CIEL) in collaboration with the International Indigenous Peoples’ Forum on Climate Change (IIPFCC), provides a comprehensive compilation of decisions, mandates, and conclusions adopted by the Parties to the UN Framework Convention on Climate Change (UNFCCC) that reference Indigenous Peoples and traditional knowledge up to 2025.

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.

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.

This executive summary introduces the 'Principles for Taxonomy Interoperability,' a contribution to COP30 developed by the Roadmap for Advancing Interoperability and Comparability of Sustainable Finance Taxonomies initiative. The document outlines seven principles designed to help policy designers and developers create sustainable finance taxonomies that are interoperable, usable, and credible, thereby facilitating the international flow of capital between developed and emerging markets.

This executive summary introduces the 'Principles for Taxonomy Interoperability,' a contribution to COP30 developed under the 'Roadmap for Advancing Interoperability and Comparability of Sustainable Finance Taxonomies.' The document provides seven guiding principles for policymakers and taxonomy developers to ensure that sustainable finance classifications are comparable across different jurisdictions, facilitating the cross-border flow of capital between developed and emerging markets.

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.

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.

In Q3 2025, the global cumulative volume of aligned GSS+ debt reached USD 6.5 trillion, with quarterly issuance of USD 233.2 billion. Non-financial and financial corporates were the leading issuer types, while the IBRD remained the most active individual issuer. Green bonds continue to dominate the market, though sustainability-labelled debt is showing increasing momentum.

This document outlines the methodology used by the Climate Policy Initiative (CPI) to estimate bottom-up climate finance needs by collecting and standardizing data from Nationally Determined Contributions (NDCs). It distinguishes bottom-up needs—finance required by countries to reach national targets—from top-down needs, which are derived from predictive models to align with a 1.5°C pathway.

This technical brief describes Phase 2 of the Carbon Rating Framework developed by the Climate Policy Initiative (CPI). The framework aims to integrate emissions performance into financial decision-making by assigning a carbon rating (CR1–CR10) based on a company's emissions intensity relative to its revenue. Phase 2 involved testing the framework on a sample of 50 companies to validate its feasibility and ability to differentiate emissions performance across various sectors.

The 'Global Landscape of Climate Finance 2025: EMDE Spotlight' fact sheet analyzes climate finance flows to emerging markets and developing economies (EMDEs). It reports that while total climate finance to these 157 countries surpassed USD 1 trillion in 2023, there remains a significant gap compared to the estimated USD 4 trillion required annually by 2030. The document highlights the dominance of China in overall flows, the growth of domestic private financing in emerging markets, and the persistent underfunding of adaptation and hard-to-abate sectors.

The Global Landscape of Climate Finance 2025 summary handout reports that global climate finance reached a record USD 1.9 trillion in 2023, driven largely by private sector growth. Despite this increase, a significant gap remains between current flows and the investment needed to meet global climate goals, with mitigation finance dominating the landscape while adaptation finance saw a decline in 2023.

The IDFC Green Finance Mapping Report 2025 analyzes the 2024 green finance commitments of 23 member national and regional development banks. While total green finance decreased by 13% to $173 billion, the majority of members increased their individual commitments. The report highlights a continued dominance of mitigation finance, a rebound in adaptation finance, and a growing but still limited focus on biodiversity and other environmental objectives.

This executive summary by the Climate Policy Initiative (CPI/PUC-Rio) analyzes 30 international financial mechanisms designed to support tropical forests, focusing on conservation, restoration, and the reduction of deforestation. The report identifies a significant funding gap, noting that while current mechanisms mobilize US$ 25.9 billion, the United Nations Environment Programme (UNEP) estimates a need for US$ 66.8 billion annually until 2030 to realize full forest potential.
