The document translates the ICJ's advisory opinion into practical tools for climate litigation, focusing on the 'stringent due diligence' States must exercise to regulate private actors, particularly in the fossil fuel industry. It highlights that States may be in breach of international obligations if they fail to prevent significant climate harm through the production, licensing, or subsidizing of fossil fuels. The brief also connects these findings to specific case categories, including licensing, duty to regulate, corporate frameworks, accountability for loss and damage, and greenwashing, emphasizing the 1.5°C temperature goal as a legal standard.

The document distills the International Court of Justice (ICJ) 2025 advisory opinion to assist practitioners in seeking climate-related remedies. It establishes that State responsibility for climate harm is governed by customary international law and can trigger a full range of legal consequences, including cessation, non-repetition, and reparation (restitution, compensation, and satisfaction). The note clarifies that a plurality of contributors does not exempt individual States from responsibility and that scientific evidence allows for the determination of each State's total contribution to global emissions. It further outlines how these findings apply to human rights cases, corporate accountability litigation, and inter-State proceedings.

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 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 document translates the ICJ's 2025 advisory opinion into practical tools for climate litigation, focusing on government framework cases, adaptation, remedies, the right to a healthy environment, corporate conduct, climate finance, speculative interventions, and regulatory rollbacks.

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.

In 2025, the EU power sector reached a tipping point as wind and solar generated 30.1% of electricity, surpassing all fossil fuel sources at 29.0%. Solar generation hit a record 369 TWh, growing by 20.1% over 2024, while coal fell to a historic low of 9.2% of the mix. Despite a slight increase in gas power generation and associated import costs, renewables provided nearly half of the EU's electricity (47.7%), with solar output helping to offset low wind and hydro production caused by unusual weather in early 2025.

The document examines the efforts of 'the rest of the world' to adapt to a chaotic trade environment characterized by US tariff adjustments and the weakening of global institutions. It highlights the launch of the Future of Investment and Trade Partnership (FIT-P), a 16-member group of small states aiming to bolster the WTO and collaborate on digital trade. It also analyzes the Comprehensive and Progressive Trans-Pacific Partnership (CPTPP), noting its attempts to coordinate with the EU and ASEAN while struggling with internal institutional weaknesses, a slow accession process, and the daunting task of renegotiating most of its agreement chapters.

The IAI Directorate has advanced several strategic mandates between June 2025 and January 2026, including the expansion of its Associate network with the WMO and AGU, and the operationalization of the Indigenous Peoples Advisory Committee (IPAC). Key efforts focused on science diplomacy in preparation for UNFCCC COP30, the launch of transdisciplinary research programs on climate-health and ocean science, and the development of the IAI Science Diplomacy Center. The Directorate also expanded its educational reach through virtual courses on remote sensing and health adaptation, while pursuing new member state adhesion, specifically with El Salvador.

Pension funds, managing over USD 73 trillion globally, face systemic risks from climate change that could reduce returns by 33% by 2050. While 200 major funds have begun divesting from fossil fuels to fulfill fiduciary duties, third-party asset managers often maintain carbon-intensive investments. This misalignment has led pension funds to withdraw over USD 100 billion from managers including BlackRock and State Street.

The report analyzes 60 effect estimates from 24 peer-reviewed studies (33,801 participants) published between 2018 and 2025 to evaluate generative AI (GenAI) misinformation. It finds that GenAI-generated text currently poses a higher risk of persuasive impact than visual misinformation. The most consistently effective countermeasure is the preemptive provision of corrective information, while content labeling shows variable effectiveness depending on design and application. The authors highlight a significant global knowledge gap, as research is heavily concentrated in English-speaking, high-income countries.

The report finds that text-based generative AI misinformation poses a higher persuasive risk than visual misinformation. It identifies a significant knowledge gap due to research focusing primarily on high-income, English-speaking countries. Among countermeasures, preemptive corrective information is the most consistent and effective intervention, while content labeling shows promising but inconsistent results depending on design and application.

A coalition of environmental organisations criticises Nestlé for withdrawing from the Dairy Methane Action Alliance (DMAA), arguing that the move contradicts the company's stated climate commitments. The authors highlight that dairy and livestock account for 37% of Nestlé's total greenhouse gas emissions and urge the company to set a science-aligned methane reduction target of at least 30% by 2030, improve reporting transparency, and prioritise emissions reductions over carbon insetting.

The research paper examines how the 1989 Belgium-Luxembourg (BLEU)–USSR bilateral investment treaty (BIT) is being used as a legal threat to prevent Belgium from supporting an EU plan to back a EUR 140 billion Ukraine loan with immobilized Russian Central Bank assets. It highlights a broader trend of 'regulatory chill' where Russian entities use investor-state dispute settlement (ISDS) claims to challenge sanctions. The author argues for the modernization of investment treaties and the implementation of domestic legal blocks to prevent the enforcement of arbitration awards that contradict international sanctions regimes.

The report finds that the EU is not on track to meet its 2030 interconnection targets, with 80% of the power system expected to miss the goal. To reach an optimal grid by 2040, Europe needs to nearly double its interconnection capacity, adding 151 GW. This expansion requires an estimated €150 billion in investment, leaving a €30 billion public funding gap in the proposed 2028-2034 Connecting Europe Facility for Energy (CEF-E) budget.

The report finds that while OECD pension funds have significantly increased their climate target-setting and risk management since 2020, their portfolios remain heavily exposed to fossil fuel expansion. Pension funds often outperform other financial institutions in areas like policy engagement and emissions disclosure once climate goals are embedded in their governance. The analysis highlights that robust regulatory frameworks in countries like the Netherlands, Denmark, and the UK drive higher adoption of targets, and suggests that the relationship between asset owners and asset managers is a critical lever for driving decarbonization.

The report finds that while OECD pension funds are increasing their climate target-setting and internal governance, their portfolios remain heavily exposed to expansionist fossil fuels. Progress is strongly linked to national regulatory environments, with the Netherlands, Denmark, and the UK leading. A critical lever for future impact is the governance of the asset owner–asset manager relationship, where leading funds are moving toward more active mandates, stricter stewardship oversight, and in some cases, the internalization of asset management to ensure alignment with net-zero goals.

The document argues that wealth taxation is an appropriate tool for redistribution in South Africa due to extreme inequality, where the richest 0.01% owned 15% of wealth in 2017. It examines three primary instruments: Financial Transaction Taxes (FTTs), dividend taxes, and net wealth taxes. International evidence from France shows that increasing dividend taxes from 15.5% to 46% led to a 15% increase in investment. Net wealth taxes in countries like Argentina, Spain, Norway, Switzerland, and Colombia have raised between 0.2% and 1.5% of GDP. The brief highlights administrative challenges for the South African Revenue Service (SARS) but notes the existence of a High Wealth Individual Unit as evidence of feasibility. It recommends a combination of moderate net wealth taxes, increased dividend taxes, and the introduction of an FTT, supported by tighter capital controls and international cooperation via the UN Framework Convention on International Taxation and Cooperation.

The document outlines a five-step process for governments to identify and quantify fossil fuel subsidies: applying a whole-of-government approach, establishing a comprehensive scope based on WTO standards, choosing measurement methods (price-gap vs. inventory), evaluating socio-economic and environmental impacts, and ensuring regular public disclosure. It emphasizes the use of the WTO Agreement on Subsidies and Countervailing Measures (ASCM) as a minimum baseline and highlights the role of effective carbon rates (ECRs) in improving cross-country comparability.

The paper examines the transition of African carbon market engagement from the Clean Development Mechanism (CDM) legacy to the operationalisation of Article 6.4 and 6.2 of the Paris Agreement. It warns against a continued reliance on exporting low-cost credits, which risks 'carbon grabs' and price asymmetry, where credits have been offered as low as USD 1-3 per tonne. The author proposes a 'Paris mindset' where domestic use of credits for national carbon taxes or sectoral targets is prioritised, and exports are used only for calculated surpluses. To achieve this, the document outlines five pillars of readiness: Policy & Institutions, Registry & MRV, Authorisation & Corresponding Adjustments (CAs), Safeguards & Benefit-sharing, and Finance & Market Access. It provides a comparative analysis of several African nations, noting that South Africa and Egypt are adopting a domestic-focused 'Paris' approach, while Ghana and Rwanda remain more export-led, and Kenya and Nigeria are in hybrid transitions.
