An Ember report analyzing national renewable energy targets for 2030 finds that global ambition remains aligned with a doubling of capacity rather than the tripling goal set at COP28. Despite record deployment, aggregate targets have only increased by 8% since COP28, with significant gaps remaining in both solar and wind ambitions compared to the tripling scenario.

This report by Ember analyzes the progress toward the COP28 goal of tripling global renewable energy capacity to 11 TW by 2030. While rapid deployment between 2023 and 2025 has reduced the required annual growth rate for subsequent years, IEA forecasts suggest a potential shortfall by 2030, primarily driven by wind and hydro capacity gaps and policy changes in the US and China.

This report by Ember analyzes the economic and environmental consequences of Indonesia's coal over-expansion. It finds that while production hit record highs in 2024, shrinking demand from major importers like China and India, coupled with rising production costs, is eroding company profits and state revenues. Additionally, the report highlights a significant underreporting of coal mine methane (CMM) emissions, which are projected to increase by 25% by 2030 due to the expansion of underground mining.

This report provides an overview of China's green hydrogen value chain—comprising production, storage and transport, and utilization—to identify investment opportunities and challenges for climate tech investors.

This report by the Climate Policy Initiative and Pontifical Catholic University of Rio de Janeiro maps 30 international financial mechanisms designed to support tropical forests. It identifies a significant funding gap, noting that current mechanisms mobilize US$ 25.9 billion, which is far below the US$ 66.8 billion annually required by 2030 to unlock the full potential of tropical forests.

This RMI briefing outlines the roles of key countries and regions—China, Brazil, India, Southeast Asia, and the United States—in the global energy transition as they approach COP30 in Belém, Brazil. It highlights the shift from high-level commitments to tangible actions, such as large-scale renewable deployment, the development of low-carbon shipping hubs, and subnational leadership in the US.

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.

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.

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.

The report identifies 30 international financial mechanisms mobilizing US$ 25.9 billion for tropical forests, though this remains far below the US$ 66.8 billion annual requirement estimated by UNEP. Financing is concentrated in conservation and is heavily skewed toward a few countries like Brazil and Guyana. While REDD+ mechanisms provide over half of the identified funding, there is a significant gap in the actual disbursement of planned funds, particularly from private and blended sources.

The report identifies 30 international financial mechanisms mobilizing US$ 25.9 billion for tropical forests, though this is far below the US$ 66.8 billion annual need estimated by UNEP for 2030. While Brazil and Guyana have high access to these funds, many high-potential countries remain underserved. Financing is dominated by credit, grants, and results-based payments (especially JREDD+), with a strong current focus on conservation over restoration and deforestation reduction.

This guide provides a structured framework for governments to develop and implement national or subnational fossil fuel subsidy (FFS) phase-out plans. It advocates for a whole-of-government approach to coordinate across ministries and proposes a three-category classification system to prioritize subsidies based on their risk to energy security, social stability, and political feasibility. The framework aims to move governments from general commitments to actionable, time-bound implementation roadmaps.

This report provides a comparative analysis of global electricity tariff-setting methodologies, focusing on the process of determining revenue requirements and conducting Cost of Supply (CoS) studies. It examines various regulatory models—including rate-of-return, incentive-based, performance-based, and market-based pricing—and evaluates their effectiveness in balancing financial sustainability for utilities with affordability for consumers. The document concludes with specific recommendations for South Africa to modernize its tariff structures and revenue determination processes as it transitions toward a wholesale electricity market.

This report by Ember, developed for the Global Offshore Wind Alliance (GOWA), provides a comprehensive analysis of global offshore wind targets across national, subnational, and regional levels. It examines current ambitions, deployment projections for 2030, and the potential for expansion in countries without existing targets, while highlighting the gap between political ambitions and projected delivery.

This research paper analyzes the evolution of Nigeria's climate policy and governance, highlighting a persistent struggle with institutional fragmentation and the misalignment of petroleum policies with climate goals. It examines the transition through four 'policy moments,' the impact of International Oil Company (IOC) divestments, and the recent centralization of climate authority under President Bola Ahmed Tinubu through the creation of the Office of the Special Presidential Envoy on Climate (OSPEC) and the Presidential Climate Action Committee (PCAC).

This research paper analyzes Nigeria's climate policy and diplomacy, arguing that while the country has established a comprehensive policy architecture, its effectiveness is severely hampered by institutional fragmentation, inter-ministerial competition, and a lack of elite consensus. The author examines the shift toward centralized governance under President Bola Ahmed Tinubu and the challenges of aligning domestic petroleum interests with global energy transition goals.
