The document provides a structured analysis of the International Court of Justice (ICJ) advisory opinion (AO) delivered on 23 July 2025, specifically focusing on how its findings can be applied to climate adaptation litigation. It details binding obligations under the UNFCCC and Paris Agreement, the intersection of adaptation with human rights law, and the ICJ's rejection of arguments that the cumulative nature of climate change exempts individual States from responsibility. The guide also categorizes types of litigation—including human rights-based cases, national planning challenges, corporate accountability, and infrastructure projects—where these legal excerpts are most applicable.

The document analyzes the legal implications of the ICJ's 2025 advisory opinion for 'government framework cases,' which target emissions reduction targets and regulatory frameworks. It details how the ICJ clarified that 1.5°C is the primary temperature goal of the Paris Agreement and established a 'stringent' due diligence standard for States in preparing and implementing Nationally Determined Contributions (NDCs). The guide highlights that NDCs must reflect a State's 'highest possible ambition' and be capable of making an adequate contribution to the 1.5°C goal. It also emphasizes the application of customary international law regarding the duty to prevent significant transboundary harm and the duty to cooperate, regardless of treaty membership. Furthermore, the document connects climate action to human rights obligations and intergenerational equity, providing a legal basis for courts to order remedies such as the adoption of consistent NDCs or full reparation.

The ICJ AO Litigation Notes Digest synthesizes the International Court of Justice's 2025 advisory opinion, establishing that States have stringent due diligence obligations to prevent significant harm to the climate system. It clarifies that the 1.5°C goal is the primary temperature target under the Paris Agreement and that the right to a clean, healthy, and sustainable environment is a precondition for other human rights. The digest details the legal consequences of breaches, including obligations of cessation and reparation, and emphasizes that climate obligations are erga omnes, meaning all States have a legal interest in their protection.

The document analyzes the current state of negotiations for a global plastics treaty after INC-5.3, focusing on the 'start-and-strengthen' model. It argues that for such a model to succeed, a treaty must include clear global objectives, enforceable obligations, effectiveness evaluations, and a procedural path for normative evolution. The brief compares three Chair's drafts and various member state proposals, concluding that many current drafts risk becoming 'bottom-up' models based on voluntary national actions, which could lead to regulatory fragmentation and insufficient collective action to end plastic pollution.

The report details how industrial actors employ strategies such as suppressing harmful data, funding biased research, and using front groups to avoid regulation of toxic chemicals. It provides case studies on PFAS, Bisphenol A (BPA), benzene, and neonicotinoids to illustrate these patterns of disinformation. The document concludes that to protect public health and the environment, companies producing hazardous substances should be prohibited from influencing the formulation of the policies that regulate them.

The document outlines a 'playbook' of industry tactics used to block chemical regulations, including the suppression of harmful data, the funding of biased research, and the use of front groups. It provides detailed case studies on PFAS, Bisphenol A (BPA), benzene, and pesticides to illustrate these patterns. The authors argue that because of this history of manipulation, chemical manufacturers and their trade associations should be prohibited from participating in the regulatory processes that govern their products, similar to the WHO's approach to the tobacco industry.

The document outlines a 'playbook' of corporate strategies used to avoid regulation of hazardous substances, including withholding data, undermining independent science, and using front groups. It provides case studies on PFAS, Bisphenol A (BPA), benzene, and neonicotinoids to illustrate these tactics and recommends banning industry participation in regulatory policymaking to protect human health and the environment.

The ISP-CWP will hold its first Plenary session from February 2-6, 2026, in Geneva to finalize foundational governance elements. Key agenda items include the Rules of Procedure, a Conflict of Interest Policy, and the Work Program and Deliverables Process. The document warns that consensus-based decision-making may lead to 'lowest-common-denominator' outcomes and that restrictions on observer participation, the conflation of Indigenous Peoples with local communities, and the exclusion of gender-responsive science could undermine the Panel's legitimacy and effectiveness.

The document examines the application of the Polluter-Pays Principle (PPP) to the PFAS pollution crisis, noting that clean-up costs in Europe could exceed €100 billion per year. It argues that the PPP must be expanded to cover legacy, present, and future pollution, regardless of whether it was legal at the time, and should target both producers and users. The authors recommend combining taxes, fees, and extended producer responsibility (EPR) schemes with strict phase-out measures and criminal penalties to ensure that the financial burden of direct and indirect societal costs is shifted from citizens to polluters.

The document details a proposed expansion of at least 45 ammonia facilities in the US, primarily in Texas and Louisiana, which could quadruple production. It critiques the 'blue ammonia' label as greenwashing, noting that carbon capture systems often fail and that ammonia is a highly toxic substance. The text highlights the dangers of ammonia leaks to human health and aquatic ecosystems, citing specific recent disasters in Oklahoma, Iowa, and Illinois, and argues against creating speculative markets for ammonia as a shipping fuel or energy carrier.

The authors argue that the UN climate process is outdated and allows powerful countries and polluting industries to block ambition. They propose four key reforms: implementing majority voting when consensus fails, enforcing strict conflict-of-interest rules to exclude fossil fuel lobbyists, establishing meaningful accountability and compliance mechanisms for state commitments, and guaranteeing human rights and transparency in negotiations.

A guide published by CIEL and other organizations detailing how the International Court of Justice's July 2025 Advisory Opinion on climate change obligations can be used by negotiators at COP30 to increase climate ambition and accountability.

The report examines how the UNFCCC's reliance on consensus has led to a 'race to the bottom,' where a small number of countries can veto critical decisions on fossil fuels, 1.5°C targets, and loss and damage. By comparing the UNFCCC to other UN bodies and multilateral environmental agreements—such as the UN General Assembly and the Montreal Protocol—the author demonstrates that voting mechanisms can actually enhance multilateralism by brokering consensus and exposing blockers. The document proposes two primary procedural pathways for reform: adopting the long-bracketed draft rules of procedure or amending the Convention and Paris Agreement via a three-fourths majority vote.

The report documents the increasing recognition of Indigenous Peoples and traditional knowledge within the UNFCCC process, listing specific references across various policy areas including adaptation, finance, and technology. It highlights the role of the Local Communities and Indigenous Peoples Platform (LCIPP) and emphasizes the necessity of a rights-based approach to climate action, grounded in the UN Declaration on the Rights of Indigenous Peoples.

The document examines how the Investor-State Dispute Settlement (ISDS) system enables foreign investors, particularly from the fossil fuel industry, to claim compensation from states for climate policies. It highlights the 'regulatory chill' effect, where the threat of costly awards—which have increased from an average of $25 million (1994-2003) to over $250 million (2014-2023)—deters governments from phasing out fossil fuels. The briefing references July 2025 advisory opinions from the International Court of Justice and the Inter-American Court of Human Rights to affirm state duties to regulate polluting conduct. It concludes that current reform efforts, including the EU and UK withdrawals from the Energy Charter Treaty (ECT), are insufficient due to sunset clauses and inadequate carve-outs, and recommends coordinated UN-level action to eliminate ISDS threats to climate and human rights obligations.

The report details the Inter-American Court of Human Rights' (IACtHR) Advisory Opinion 32/25, which recognizes the right to a healthy climate as an autonomous and justiciable right. It establishes that States have binding obligations to mitigate greenhouse gas emissions, adapt to climate impacts, and provide integral reparations. The Court introduces a high standard of 'enhanced due diligence' for climate action and recognizes Nature as a subject of rights. It also outlines specific protections for vulnerable groups, including Indigenous Peoples, LGBTIQ+ persons, persons with disabilities, and future generations, while emphasizing the necessity of environmental democracy through access to information, public participation, and the protection of environmental defenders.

The document provides a comprehensive analysis of the IACtHR's Advisory Opinion OC-32/25, which recognizes the right to a healthy climate as an autonomous and justiciable right. It details the court's findings on the obligations of states to mitigate greenhouse gas emissions, adapt to climate impacts, and cooperate internationally. The report emphasizes the recognition of Nature as a subject of rights and the establishment of a reinforced due diligence standard for preventing climate damage. It also explores the specific protections required for vulnerable groups, including indigenous peoples, LGBTIQ+ individuals, persons with disabilities, and future generations, while outlining the necessity of comprehensive climate reparations and environmental democracy.

The report examines the ecological and human rights risks associated with atmosphere-based, marine, and land-based geoengineering. It argues that these speculative interventions could trigger ecosystem collapse, exacerbate ocean acidification, and violate the rights of millions, particularly Indigenous Peoples and rural communities. The author advocates for the enforcement of the UN Convention on Biological Diversity's moratorium on geoengineering and a shift toward proven climate solutions.

The document provides legal proposals to integrate environmental rights into the LBI, emphasizing the need to hold transnational corporations accountable for environmental degradation and climate change. It advocates for the recognition of the RtHE, the inclusion of the financial and extractive sectors in the LBI's scope, and the implementation of strict liability for hazardous activities. The briefing also highlights the necessity of protecting environmental human rights defenders and ensuring that human rights obligations take primacy over trade and investment agreements.

The briefing paper advocates for a legally binding international instrument to end corporate impunity regarding environmental and human rights abuses. It highlights the insufficiency of voluntary frameworks and argues that the LBI can operationalize the right to a clean, healthy, and sustainable environment by establishing mandatory due diligence, extraterritorial jurisdiction, and strict liability for parent companies across global value chains.
