The report argues that the end of fossil fuel advertising is inevitable and that marketing agencies must proactively 'off-ramp' these clients to avoid financial and reputational damage. It estimates that the top 29 oil majors spent $6.97 billion on media, creative, and PR in 2024, with $3.03 billion going to major holding companies and $3.94 billion to independent agencies. The document highlights the risks of retention, citing Havas' loss of B Corp certification and Edelman's 5% revenue decline in 2024. It proposes a phased exit strategy ending in 2030, suggesting agencies pivot toward high-growth sectors including healthcare (projected $36.4 billion marketing value by 2030), renewables, and the circular economy (a $4.5 trillion global opportunity by 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.

ClientEarth outlines three legal imperatives for COP30: combating climate disinformation, translating the ICJ's Advisory Opinion into 1.5°C-compatible domestic laws, and establishing enforceable corporate accountability for environmental harms. The brief emphasizes the transition from voluntary pledges to mandatory legal compliance to ensure the goals of the Paris Agreement are met.

The report examines the role of social media platforms in spreading climate disinformation, highlighting how algorithmic systems and revenue-sharing models incentivise misleading content. It specifically assesses the compliance of Very Large Online Platforms (VLOPs) with the EU Digital Services Act (DSA), concluding that most have failed to identify or mitigate climate disinformation as a systemic risk.

The document argues that civic space in the EU is narrowing due to restrictive laws, exclusion from decision-making, and the criminalisation of peaceful activism. It highlights specific threats such as SLAPPs, funding cuts to the LIFE programme, and national laws in France, Hungary, Poland, and Italy that curtail CSO operations. ClientEarth calls for a pro-CSO narrative, transparent access to decision-making, and stable long-term financial support to safeguard environmental democracy.

The Just Transition Compass serves as a non-prescriptive guide to move Just Transitions from high-level dialogue to concrete implementation. It defines core principles of distributive, procedural, and restorative justice, identifies systemic barriers to national implementation—such as limited subnational capacity and siloed finance—and analyzes the political tensions within the UNFCCC's Just Transition Work Programme (JTWP). The report advocates for a permanent international coordination mechanism to align fragmented efforts, manage the cross-border impacts of unilateral trade measures like the EU's CBAM, and mobilize private capital through sustainable finance taxonomies.

The Just Transition Compass establishes a framework to move from high-level climate commitments to scalable, justice-focused implementation. It identifies four core elements of a just transition—restorative, distributive, procedural, and climate justice—and argues that domestic transitions require international cooperation to avoid economic spillovers and financial inequalities. The document proposes the creation of a permanent Just Transition Coordination Unit within the UNFCCC to reduce fragmentation, align financial flows, and provide capacity support to countries.

The report outlines a systematic approach to estimating bottom-up climate finance needs by extracting data from 167 NDCs. It distinguishes bottom-up needs—finance required by countries to reach national targets—from top-down needs, which are derived from predictive models for 1.5°C pathways. The methodology involves standardizing diverse data on sector classification, timeframes, and currency (converting to 2023 USD), while categorizing finance as unconditional (domestic) or conditional (international). The document acknowledges significant data gaps, noting that less than half of the reviewed NDCs provide fully costed needs, and that current bottom-up estimates are insufficient to align with a net-zero pathway.

In 2023, climate finance to EMDEs surpassed USD 1 trillion, with 80% sourced domestically and China accounting for 64% of total flows. While mitigation finance grew to USD 979 billion, it remains far below the estimated USD 3.86 trillion annual need. Adaptation finance totaled USD 48 billion, showing significant unevenness as the top 20% of countries received over 70% of these funds. International public finance exceeded USD 159 billion, but faces potential declines due to ODA cuts, while international private finance rose to USD 49 billion. The report emphasizes that EMDEs require nearly USD 4 trillion annually through 2030 to achieve climate goals.

Global climate finance reached a record USD 1.9 trillion in 2023, driven by a 30% compound annual growth rate in private finance from 2018 to 2023. While mitigation finance dominates at 94% of total flows—primarily targeting energy systems and transport—adaptation finance decreased by 16% in 2023 to USD 65 billion. Significant regional disparities persist, with 79% of finance concentrated in East Asia and the Pacific, Western Europe, and the US and Canada. Despite growth, current investment levels remain three times lower than the most conservative estimates of global needs.

In 2024, IDFC members committed $173 billion in green finance, a 13% decrease from 2023, primarily driven by shifts in investment priorities among a few large institutions. Despite the overall decline, 14 of 23 responding members increased their commitments. Climate finance dominated at $167 billion, with mitigation ($140 billion) remaining the primary focus, while adaptation finance saw a 54% increase to $17 billion. Biodiversity finance totaled $8 billion. The report highlights the pivotal role of non-OECD institutions, which provided 72% of climate finance, and emphasizes the need to target underfunded sectors such as AFOLU, fisheries, and industry.

The report catalogs 30 operational financial mechanisms for tropical forests, totaling US$ 25.9 billion in planned, issued, and disbursed funds. It highlights a significant funding gap compared to the US$ 66.8 billion annually needed by 2030, noting that 31% of identified funds have not yet been disbursed. The analysis emphasizes that while conservation currently dominates funding, restoration offers higher potential for private and blended finance, and jurisdictional REDD+ remains the most significant instrument, representing over US$ 15.3 billion.
