It distills the ICJ's findings on State obligations under climate treaties and human rights law, emphasizing the legally binding nature of adaptation planning and financial support for developing nations.

This fact sheet by RMI explains the liquefied natural gas (LNG) supply chain, the United States' role as a leading exporter, and the environmental and economic impacts associated with the liquefaction and transport of gas over long distances.

This fact sheet provides a comprehensive profile of the global copper value chain, detailing production, reserves, market concentration, and the impact of the energy transition. It highlights the dominance of China in refining and smelting, the role of major producers like Chile and the Democratic Republic of the Congo, and the challenges associated with recycling and ore grade decline.

The report 'Boom and Bust Coal 2026' by Global Energy Monitor analyzes the global coal plant pipeline in 2025, highlighting a growing disconnect where coal capacity continues to increase—driven primarily by China and India—while actual coal-fired electricity generation declines due to the rapid expansion of wind and solar power.

This briefing by Zero Carbon Analytics examines how climate change is reducing the quantity and quality of sparkling wine globally. It details the impact of extreme weather on yields and pricing in key regions like France, Spain, and Italy, the chemical changes in grapes that alter flavor profiles, and the risks to agricultural workers. The document also discusses the limitations and costs of adaptation measures, noting that traditional wine-growing regions face a high risk of becoming unsuitable if global temperatures rise by 2°C or more.

This briefing by Zero Carbon Analytics challenges the claim that renewable energy increases electricity prices, arguing that real-world data from the US, EU, Australia, and India often show a correlation between high renewable uptake and below-average power prices.

The steel industry, responsible for 8% of global greenhouse gas emissions, faces a critical need for decarbonization as demand is projected to rise 39% by 2050. While integrated blast furnaces (BF-BOF) dominate production, the report identifies Hydrogen-DRI as the only current net-zero commercial technology, though it struggles with high costs and hydrogen availability. The authors propose a three-pronged innovation strategy: 'Make Less' (circularity and alternative materials), 'Make Better' (retrofitting and improving DRI), and 'Make New' (disruptive low-temperature and modular furnaces). To overcome capital intensity, the report suggests startups target high-margin niche products like high-purity iron and monetize industrial waste streams to gain commercial traction.

This executive summary from the Climate Policy Initiative (CPI) analyzes the climate transition progress of 594 pension funds in OECD countries, representing USD 22.5 trillion in assets. Using the Net Zero Finance Tracker (NZFT), the report evaluates these funds across targets, implementation, and impact, highlighting a trend of increasing climate target adoption and improved risk management, while noting a persistent material exposure to fossil fuel expansion.

This report by the Climate Policy Initiative and Climate Bonds Initiative analyzes the integration of methane abatement within five sustainable finance taxonomies (Colombia, EU, Indonesia, South Africa, and Thailand). It identifies systemic gaps in sectoral coverage, technical rigor, and criteria specificity, and provides a best-practice framework to mobilize investment toward high-impact methane reduction.

This research paper examines the intersection of international trade regulations and Africa's ambitions for green technology and industrialisation. It specifically analyzes the potential impacts of the European Union's Carbon Border Adjustment Mechanism (CBAM) and US tariffs, arguing that while these measures could theoretically drive demand for renewables, they are more likely to create fiscal constraints and hinder the continent's ability to invest in green R&D. The author advocates for a coordinated African response through the UNFCCC, the WTO, and the African Continental Free Trade Area (AfCFTA) to secure technology transfer and affordable finance.

The NewClimate Institute's 2025 update evaluates the progress of 25 major emitters, representing over 80% of global emissions, toward their climate mitigation targets. The report finds that while total emissions under current policies may peak by 2026, the projected reductions are insufficient to meet the Paris Agreement's 1.5°C goal, which requires a 43% reduction by 2030 compared to 2019 levels.

This briefing by the International Institute for Sustainable Development (IISD) examines the intersection of international trade and climate policy ahead of COP 30. It focuses on the use of trade tools—such as border carbon adjustments, green subsidies, and deforestation-free import rules—to advance climate goals while highlighting the risks of market fragmentation and the potential for these measures to deepen inequities between developed and emerging economies.

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.
