It specifically examines how the AO's findings on State obligations—including the duty to prevent harm, stringent due diligence, and the precautionary principle—can be used to challenge reliance on speculative climate interventions (such as geoengineering and carbon capture) and offset-based mitigation measures that may delay the phase-out of fossil fuels.

This briefing note analyzes the implications of the International Court of Justice's (ICJ) July 2025 advisory opinion on States' obligations to prevent environmental harm, specifically focusing on the financing of climate-destructive conduct. It outlines how the ICJ's findings can be used in litigation to challenge public and private funding of the fossil fuel sector and to enforce obligations for climate finance in developing nations.

This briefing, produced by a coalition of climate litigation practitioners, provides structured 'Litigation Notes' to help lawyers integrate the International Court of Justice's (ICJ) July 23, 2025, advisory opinion (AO) on States' climate obligations into legal cases.

This litigation guide analyzes the 2025 ICJ Advisory Opinion to provide a legal framework for challenging 'regulatory rollbacks'—the weakening of climate and environmental protections. It highlights the ICJ's 'stringent due diligence' standard, the duty to prevent significant harm to the climate system, and the requirement for progressive NDCs aligned with a 1.5°C limit. The guide argues that rollbacks in emission standards, forest protections, and EIA procedures may constitute internationally wrongful acts, citing specific recent examples from India, Germany, Belgium, France, and the United States.

This policy brief by the Center for International Environmental Law (CIEL) analyzes the status of the global plastics treaty following the Intergovernmental Negotiating Committee's fifth session (INC-5.3) in February 2026. It specifically evaluates the 'start-and-strengthen' approach—a model where a treaty is adopted with core obligations and progressively enhanced through future decisions—contrasting it with 'bottom-up' models based on voluntary national actions. The brief examines three draft texts from the Chair and various member state proposals, arguing that for a start-and-strengthen model to succeed, the treaty must include legally operative objectives, periodic effectiveness evaluations, and a procedural path for normative evolution, such as voting mechanisms to avoid deadlocks.

This report analyzes China's position as the world's largest methane emitter and explores how sustainable finance can accelerate abatement in the energy, agriculture, and waste sectors. It highlights a significant investment gap, estimating China's annual methane abatement needs at USD 7.7 billion. While policy frameworks like the Methane Emissions Control Action Plan and updated NDCs are emerging, the report argues that a lack of quantitative targets, technical standards, and integrated MRV systems hinders private investment. It recommends incorporating methane into the national ETS, refining green taxonomies, and encouraging financial institutions to set science-based methane targets.

This report by the Climate Bonds Initiative analyzes China's methane emissions, which account for nearly 16% of the global total, and explores the role of sustainable finance in achieving abatement. It highlights a funding gap of approximately 7.7 billion USD annually and identifies significant reduction potentials in the coal, rice, and livestock sectors. While China has included non-CO2 gases in its 2035 NDC, the report notes a lack of specific quantitative methane targets and suggests the use of green bonds, sustainability-linked loans, and improved regulatory frameworks to drive investment.

This report by the Climate Bonds Initiative argues that expanding domestic renewable energy is critical for Japan's national security and strategic autonomy, given its high dependence on energy imports. It proposes a pathway to achieve an 80-90% clean energy grid by 2035-2040 through grid expansion, regulatory reform, and the mobilization of private capital.
