The Energy Charter Treaty (ECT) is criticized for allowing fossil fuel investors to use Investor-State Dispute Settlement (ISDS) to challenge climate policies, such as the Netherlands' phase-out of fossil fuels by 2030. While the EU has attempted to modernize the ECT, the requirement for unanimity among 56 contracting states has stalled progress. The document argues that withdrawal is a viable alternative, provided that the 20-year 'survival clause'—which continues to protect existing investments after withdrawal—is neutralized. Using the Vienna Convention on the Law of Treaties (VCLT), the authors argue that a group of states can legally modify the treaty 'inter se' to extinguish this clause because the ECT consists of reciprocal bilateral relations rather than obligations binding on all parties. Such a coordinated withdrawal would immediately end treaty-based fossil fuel protection and ISDS for the withdrawing states, reducing legal risks and aligning with EU climate objectives.

ClientEarth filed a complaint with UN Special Procedures alleging that Saudi Aramco is responsible for the world's largest climate-linked breach of human rights law. The UN experts issued Communications to Saudi Aramco, the Kingdom of Saudi Arabia, and several global financial institutions, asking them to clarify their compliance with the UN Guiding Principles on Business and Human Rights. The document highlights Aramco's role as a massive corporate emitter and the responsibility of banks—including JPMorgan Chase and HSBC—that facilitate its operations. It further argues that the Saudi government is failing in its duty to regulate Aramco and that the company's sustainability claims are misleading.

The Healthy NDC Scorecard evaluates national climate commitments (NDCs) based on climate ambition, health impacts, and governance. It categorizes outcomes ranging from 'Paris Agreement compliant' and 'Science aligned' to those that are 'Catastrophic for human health', specifically tracking temperature trajectories from 1.5°C to over 4°C.

The report evaluates WHA78 as a period of broadening dialogue and significant policy adoption, notably the Global Action Plan on Climate and Health (GAP) and the first pandemic agreement. While it celebrates the inclusion of youth, persons with disabilities, and mental health in the agenda, it highlights critical shortcomings, including the absence of fossil fuel phase-out language and uncertainties regarding the implementation and funding of the GAP. The document advocates for a shift in narrative, framing climate action as a strategic health investment rather than a cost, and calls for greater inclusion of Small Island Developing States (SIDS) and the Global South in leadership and R&D.

The document provides an overview of nuclear energy as a low-carbon, high-capacity power source, detailing its current contribution to the U.S. electricity mix and the challenges facing its growth. It highlights the aging state of the U.S. nuclear fleet, the lack of a permanent radioactive waste disposal solution, and the high costs and delays associated with new construction. The brief also explores emerging technologies, such as Small Modular Reactors (SMRs) and Generation IV reactors, as potential paths to maintain nuclear power's role in a decarbonized economy.

The report identifies 5,500 hazardous facilities along U.S. coasts at risk of 100-year coastal flooding by 2100 under a high-emissions scenario. It highlights a significant environmental justice gap, finding that poorer and marginalized communities are 15-41% more likely to live near these at-risk sites. The analysis emphasizes the danger of 'NaTech' disasters, where natural events trigger technological failures, leading to toxic contamination of floodwaters.

The document examines why border adjustment (BA) measures are largely absent from Japanese climate policy despite concerns over international competitiveness. It finds that Japan's reliance on voluntary emission reduction plans is inconsistent with BA, and stakeholders view such measures as technically infeasible and incompatible with WTO rules. Instead, Japan advocates for multilateral agreements that include emission commitments for major emerging economies to address carbon leakage.

The document proposes a Green Investment Scheme (GIS) to recycle revenues from Russian Assigned Amount Units (AAUs) into environmental projects. It outlines two primary implementation paths: a 'programme approach' for small, simple efficiency projects and a 'project approach' for larger, unique investments. The report identifies significant institutional barriers in Russia, including a lack of a strong national focal point and poor reporting statistics, which hinder the eligibility of AAUs for trading. It analyzes the varying requirements of potential buyers: the EU emphasizes environmental integrity and strategic energy dialogue; Japan values good governance and a mix of quantifiable and non-quantifiable activities; and Canada prefers quantifiable, project-specific investments. The authors recommend prioritizing small-scale, technically simple projects in energy efficiency, fuel switching, and renewable energy to build momentum and reduce transaction costs.

The report argues that traditional economic tools, such as cost-benefit analysis and equilibrium models, are inadequate for the structural changes required by the energy transition. It proposes a shift toward 'Risk-Opportunity Analysis' and dynamic modelling that accounts for induced innovation and learning-by-doing. Based on successes in solar PV, LED lighting, and wind power, the authors outline ten principles for policymaking, emphasizing targeted investment, risk management, and adaptive policy packages. National case studies in Brazil, China, and India suggest that while decarbonisation has a negligible impact on overall system costs and GDP, the transition requires significant up-front investment and careful management of distributional impacts, particularly in coal-dependent regions.

The briefing argues that while the transition away from fossil fuels is accelerating due to economic costs, clean energy opportunities, and geopolitical drivers, significant gaps remain in production and emissions. It highlights the vulnerability of fossil-fuel-dependent nations and the need for a 'globally just transition' supported by redirected finance, debt relief, and stronger governance to avoid economic disruption and systemic financial risks.

The first week of COP30 was characterized by significant friction between developed and developing nations over finance, trade measures, and the 1.5C temperature goal. While some progress was made in operationalizing the Fund for Responding to Loss and Damage and advancing Article 6 carbon market standards, negotiations on the Just Transition Work Programme and the Gender Action Plan stalled due to disagreements over terminology and the role of unilateral trade measures. The Brazilian Presidency launched the Belem Health Action Plan and proposed a framework for synergies between the three Rio Conventions, though many thematic areas remain bracketed heading into the second week.

The COP30 Week 2 debrief details the adoption of the 'Global Mutirão' cover decision, which calls for tripling adaptation finance by 2035 but omits references to fossil fuels and deforestation. Key outcomes include the recommendation for a Just Transition mechanism (BAM) to be operationalized in 2026, the transfer of $26.8 million to the Article 6.4 PACM, and the adoption of the Belém Gender Action Plan. However, significant tensions persisted regarding unilateral trade measures, the 1.5°C temperature goal, and the lack of concrete targets in climate finance and the Global Goal on Adaptation (GGA).

The Sharm el-Sheikh mitigation ambition and implementation work programme (MWP), established at COP26, aims to accelerate global emissions reductions through non-prescriptive dialogues and capacity-building. While COP30 confirmed the programme's continuation through 2026 and improved finance matchmaking and inclusiveness, significant divergences remain between developed and developing nations regarding the level of prescriptive guidance for sectoral pathways and the scale of financial commitments. Key areas of ongoing debate include the design of a digital platform for information sharing and the balance between global guidance and national sovereignty in managing forests and waste.

Catastrophe (CAT) bonds are high-yield debt instruments that provide rapid liquidity after natural disasters, such as hurricanes and earthquakes, by transferring risk to investors. The document details how these bonds are structured using parametric or industry-loss triggers and identifies the roles of commercial providers, multilateral development banks (MDBs), and regional pools. It outlines the internal and regulatory capacities governments need to issue these bonds, the challenges of basis risk and high transaction costs, and provides examples of sovereign issuances in countries like Mexico, Chile, and Jamaica.

FAST-Infra is a public-private partnership involving banks, asset managers, governments, and development banks aimed at accelerating private investment in sustainable infrastructure in developing countries. The initiative is developing a sustainable infrastructure labelling system to guide governments, developers, and institutional investors, alongside four pilot market mechanisms: a technology-enabled securitization platform, a global off-take/revenue guarantee provider, an open-sourced managed co-lending portfolio programme, and a sustainable financing facility for national development banks.

The paper argues that for India to achieve net-zero emissions by 2070, the iron and steel sector—responsible for 10-12% of national GHG emissions—must shift to low-carbon production. It proposes a comprehensive 'Green Steel Mission' and a national sustainable finance taxonomy to bridge the gap between conventional and green technologies. The authors emphasize the need for differentiated strategies for primary steel (BF-BOF route) and secondary steel (DRI-IF/EAF route), noting that secondary producers face higher financing barriers despite having high near-term abatement potential. Key recommendations include mandating corporate transition plans, developing a detailed sectoral technology roadmap, and adopting innovative financial instruments like Carbon Contracts for Difference (CCfD) to support low-TRL technologies.

The document provides a comparative overview of emission control regulations and OBD requirements in the European Union, India, Japan, China, the United States, Mexico, Argentina, and Brazil, detailing the specific standards used for light and heavy vehicles.

Carbon Market Watch outlines ten key elements for effective carbon pricing, arguing that such systems must be integrated into a broader policy mix, utilize absolute declining caps, and eliminate free allocations and offsets. The briefing emphasizes the need for transparency, the reinvestment of revenues into climate action and vulnerable communities, and the use of carbon border levies to prevent leakage without protecting polluting industries. It concludes that carbon pricing is a tool to be used alongside regulations and democratic engagement, rather than a standalone solution for decarbonization.

The report examines the uneven progress of carbon pricing in Asia, contrasting the advanced emissions trading systems (ETS) in Japan and South Korea with the early-stage designs in Vietnam, Indonesia, and the Philippines. It argues that while the EU CBAM poses a financial risk to exporters—particularly in the steel sector—the overall impact is limited and can be mitigated by implementing effective domestic carbon pricing and transitioning to cleaner production technologies. The document provides specific fee estimates for each country and recommends phasing out carbon offsets, implementing absolute emission caps, and shifting toward the auctioning of allowances to drive genuine decarbonisation.

The report argues that carbon pricing is a vital but insufficient tool for climate action and must be integrated into a broader policy mix. It advocates for absolute emission caps, the elimination of free allowances, and the reinvestment of revenues into public climate benefits. The document strongly warns against the use of carbon offsets and credits, which it claims undermine environmental integrity and allow polluters to avoid real reductions. It also addresses the 'carbon leakage' myth, suggesting that the risks are often overestimated and used to justify policies that lock in polluting industries.
