Jack Egan, a resident of the NSW South Coast, lost his home in Rosedale during the Currowan fire on December 31, 2019, as part of the Black Summer bushfires. This experience, which he describes as the future of global warming crashing into the present, led him to become a climate advocate. Egan has joined the Hard Truths human rights case to hold governments and fossil fuel corporations accountable for climate inaction and the expansion of coal and gas projects, seeking legal protections for current and future generations based on international law.

The Center for International Environmental Law asserts that the UNFCCC is currently hindered by a consensus model that allows a small number of countries to obstruct progress. Citing the First Conference on Transitioning Away from Fossil Fuels in Santa Marta and the UN General Assembly's resolution on the ICJ climate Advisory Opinion, the authors argue that climate action is moving beyond the UNFCCC and that the body must evolve to incorporate majority voting, address corporate capture, and operationalize legal obligations to prevent climate harm.

The document examines how the reliance on consensus in the UNFCCC has led to a 'race to the bottom,' resulting in watered-down agreements on fossil fuels, science-based targets, and loss and damage. It proposes two procedural pathways for reform: adopting the long-delayed draft Rules of Procedure or amending the Convention itself. To support this, the author provides a comparative analysis of other UN institutions and multilateral environmental agreements—such as the Montreal Protocol and the Green Climate Fund—that successfully utilize voting to break deadlocks and advance substantive goals.

The authors argue that the upcoming UN General Assembly resolution to operationalize the International Court of Justice's (ICJ) Advisory Opinion on climate change is a critical test of global climate leadership. They assert that the resolution reflects existing legal obligations to prevent climate harm, provide reparations, and ensure a just transition from fossil fuels. While noting resistance from major emitters and oil producers who seek to weaken the text, the authors maintain that the resolution complements existing UNFCCC processes by closing an 'accountability gap' that the treaty regime has failed to address.

Mallory Stewart testifies that the U.S. must lead the development of international guardrails and rules of responsible behavior in outer space to avoid unintentional escalation and prevent China and Russia from defining future space security policy. Stewart emphasizes the need for the State Department to lead a unified space diplomacy policy, improve interagency coordination, and restart bilateral and multilateral space security dialogues to strengthen alliances and protect U.S. national security and commercial interests.

The Tassiriki Call, adopted in April 2026, outlines a vision for a Fossil Fuel Free Pacific based on 100% renewable energy and the 1.5°C temperature limit. It advocates for a global Fossil Fuel Treaty, scaled-up grant-based finance, and the creation of an Inter-Governmental Taskforce for a Just Transition to a Fossil Fuel Free Pacific. The statement emphasizes the need for a managed decline of fossil fuel production and warns against the use of carbon capture and geoengineering to justify continued production.

The Fossil Fuel Treaty Initiative is calling for countries to participate in discussions to design a binding legal instrument for a global just transition from coal, oil, and gas. The proposed treaty is based on three pillars: resourcing and cooperation for a just transition, ending new fossil fuel projects, and an equitable phase-out of existing projects aligned with the 1.5°C goal. Joining the bloc creates no immediate legal or financial obligations for participating nations, but allows them to shape the treaty's form, scope, and timeliness. The initiative aims to establish a transition finance support framework to facilitate debt resolution, renewable energy investment, and economic diversification. Participating countries are asked to affirm support, appoint political and technical focal points, work collectively on the treaty mandate, use diplomatic channels to recruit other states, and support the adoption of a negotiating mandate.

The ICJ Advisory Opinion establishes that states must implement multilateral environmental agreements (MEAs) in a coherent, integrated manner, meaning that climate-related duties must inform the implementation of treaties like the Convention on Biological Diversity and the UN Convention to Combat Desertification. Consequently, evidence of systemic and mutually reinforcing actions across different MEAs will now be used to assess a state's due diligence and compliance with international law, increasing the legal and reputational risks of poorly coordinated policy implementation.

This policy brief examines the implications of the International Court of Justice (ICJ) advisory opinion on climate change for multilateral environmental agreements (MEAs), emphasizing that states must now implement climate provisions in an integrated and systemic manner to ensure compliance with international law.

The document argues that climate adaptation is a binding legal obligation under international law and treaties, rather than a discretionary domestic policy choice. It outlines how states must demonstrate due diligence by using the best available scientific data, prioritizing vulnerable populations, and implementing national adaptation plans by 2030. Additionally, it recommends that developed nations provide financing, technology transfers, and capacity building to developing countries to meet these obligations.

This briefing by the International Institute for Sustainable Development examines the implications of the International Court of Justice (ICJ) Advisory Opinion on the Obligations of States in Respect of Climate Change, specifically regarding climate adaptation. It argues that adaptation is a binding legal obligation under customary international law and climate treaties, rather than a voluntary domestic policy choice, requiring states to exercise due diligence to prevent foreseeable climate harm.

The document examines how the 2025 ICJ Advisory Opinion shifts climate adaptation from a voluntary domestic policy choice to a legally binding international obligation. It details the procedural and substantive obligations under the UNFCCC and Paris Agreement, the application of a 'due diligence' standard to assess state compliance, and the binding requirements for developed countries to provide adaptation finance and support. The brief also highlights the intersection of adaptation with international human rights law and other multilateral environmental agreements, recommending that states integrate these frameworks to ensure legal robustness and effective resilience.

The document examines how the ICJ's 2025 advisory opinion shifts climate adaptation from a voluntary national choice to a binding international legal obligation. It details the procedural and substantive requirements for states, the application of the 'due diligence' standard to evaluate compliance, and the mandatory role of developed countries in providing financial and technical support to developing nations. The briefing also highlights the intersection of adaptation with human rights and other multilateral environmental agreements.

The briefing examines the legal implications of the 2025 ICJ Advisory Opinion on climate change, arguing that the provision of fossil fuel subsidies may constitute an internationally wrongful act. It extends this reasoning to other harmful subsidies, such as those in agriculture and plastics, and provides recommendations for states to reduce legal risk through transparent, phased reforms and international coordination via the Coalition on Phasing Out Fossil Fuel Incentives Including Subsidies (COFFIS).

The document argues that the ICJ's 2025 advisory opinion transforms the removal of fossil fuel subsidies from a political commitment into a legal imperative, as such subsidies may constitute an 'internationally wrongful act'. It suggests this reasoning extends to other harmful subsidies, such as those in agriculture and plastics, increasing the legal risk for states. The briefing recommends that governments implement transparent, gradual phase-out plans, prioritize social protection over production subsidies, and coordinate internationally through initiatives like the Coalition on Phasing Out Fossil Fuel Incentives including Subsidies (COFFIS).

The document analyzes how the ICJ's 2025 Advisory Opinion rejects the 'lex specialis' doctrine, establishing that the UN climate regime and other multilateral environmental agreements (MEAs), human rights law, and customary international law mutually inform and reinforce one another. It argues that states must integrate climate considerations into the implementation of treaties such as the Convention on Biological Diversity and the UN Convention on the Law of the Sea to demonstrate due diligence and avoid legal consequences for non-compliance.

The document examines the 2025 ICJ advisory opinion, which establishes that climate obligations are not isolated to the UN climate regime but are reinforced by other multilateral environmental agreements and human rights law. It argues that states must implement these obligations in an integrated manner to demonstrate due diligence and avoid legal consequences for inaction.

The document argues that African diplomacy at the UN is evolving into a distinct form of realpolitik that blends enduring values with strategic calculation. This approach is evidenced by voting patterns on conflicts in Gaza and Ukraine, where states use abstentions to maintain strategic autonomy. The brief highlights key institutional gains, such as the AU's permanent G20 seat and UN Security Council Resolution 2719 for financing AU-led peace operations, while noting that challenges in coordination, capacity, and consistency persist. Ultimately, it posits that Africa uses moral and legal narratives not to cloak domination, but to resist it and negotiate influence within an asymmetrical international system.

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 author contends that recent violations of international law—including US actions in Venezuela and conflicts in Ukraine and Gaza—demonstrate the impotence of violence. The text advocates for a shift toward 'non-violence' as a political tool and a global common good, linking peace to social and environmental justice. It calls on the European Union to champion this approach by upholding the UN Charter, the Paris Agreement, and the 2030 Agenda for Sustainable Development.
