The Inter-American Institute for Global Change Research (IAI), alongside the Alliance for Just Deliberation on Solar Geoengineering (DSG) and The Degrees Initiative, conducted a workshop series culminating in an in-person simulation in Bogota, Colombia. The program aimed to empower policymakers and technical specialists from Latin America and the Caribbean (LAC) to navigate the complexities of solar radiation modification (SRM) governance. Participants identified critical needs for regional research to understand local physical and socio-economic impacts, noting a disparity between the region's low greenhouse gas emissions and its high climate vulnerability. Discussions highlighted the risk of SRM creating a "moral hazard" that could divert attention from Paris Agreement commitments, specifically Nationally Determined Contributions (NDCs). The report emphasizes the necessity of strengthening science-policy interfaces, ensuring the participation of Indigenous Peoples through free, prior and informed consent, and fostering South-South and triangular cooperation to enhance regional data access and institutional knowledge.

The document assesses the UN climate regime's transition to the 'implementation era' following the completion of the Paris Agreement rulebook. It identifies systemic inefficiencies, including a predominance of procedural decisions (87%) over substantive ones, overlapping mandates among 17 constituted bodies, and significant funding gaps for adaptation. The authors argue that the regime is hindered by a de facto veto system based on consensus and the influence of fossil fuel lobbyists. Key recommendations include adopting formal voting rules, closing the Kyoto Protocol's remaining structures to save an estimated €62 million over five years, and operationalizing new governance platforms like a UN Climate Council. The brief also emphasizes the need to address structural drivers of the crisis, such as overconsumption and corporate impunity, while leveraging the 2025 ICJ Advisory Opinion to strengthen legal accountability for both states and non-state actors.

The document argues that the UN climate regime, comprising the UNFCCC, Kyoto Protocol, and Paris Agreement, is currently hindered by procedural complexity, fragmented institutional structures, and a lack of accountability. It highlights that 87% of recent decisions are merely procedural and recommends a systemic overhaul, including the formal closure of the Kyoto Protocol, the adoption of majority voting to replace consensus, and a shift toward a more active implementation role for the UNFCCC Secretariat. The authors emphasize the need for a new climate finance goal of at least $300 billion annually by 2035 and the integration of ethical considerations and structural causes of the climate crisis into future governance.

The guide offers ten tips for Climate Week NYC 2025 attendees, focusing on time management, attire, networking strategies, and mental well-being. It emphasizes the need for buffer time for security and travel, the importance of prioritizing events to avoid burnout, and the value of authentic connections over corporate jargon and 'spin'. Logistical advice includes using unlimited data for navigation and preparing outfits in advance to reduce mental load.

The International Organisation for Standardisation (ISO) and the Greenhouse Gas Protocol (GHG-P) announced a partnership on 9 September 2025 to merge and align their greenhouse gas accounting frameworks. The collaboration focuses on three core areas: corporate footprints, product footprints, and project-level GHG accounting. While the authors welcome the potential for a unified global framework to reduce fragmentation and reporting burdens, they warn that harmonisation must not lead to the dilution of standards. Specifically, they argue that carbon credits must not be treated as substitutes for direct emission reductions and that scope 3 accounting must not be artificially lowered through certificate trading. The authors also emphasize that the governance of the new standards must be transparent and inclusive to prevent the overrepresentation of large corporate interests, suggesting a model that combines ISO's regulatory recognition with GHG-P's transparency and stakeholder breadth.

The Francophone court of first instance in Brussels ruled that the Belgian federal government and the regional governments of Wallonia, Brussels, and Flanders breached their duty of care under the Belgian Civil Code and violated Articles 2 and 8 of the European Convention on Human Rights. The court found this breach was based on ineffective climate governance, mixed results in emission reductions, and ignored warnings from the European Union. However, the court rejected the plaintiffs' request to set specific binding emission targets, citing the principle of separation of powers. The case is currently pending following an appeal filed on 17 November 2021.

The report examines climate governance, targets, monitoring processes, and compliance mechanisms in the UK, EU, Germany, US, Japan, and South Korea. It argues that monitoring frameworks are essential for translating long-term net-zero visions into actionable policies and corrective actions, specifically to support Southeast Asian nations in their energy transitions.

The document identifies 14 distinct tactics of climate obstruction used during UNFCCC negotiations, ranging from overt rejection to subtle procedural delays. It argues that obstruction is unevenly distributed, with wealthier and fossil-fuel-producing nations exercising disproportionate influence. The brief maps these tactics across negotiation stages and predicts their likely application at COP30 in areas such as the Global Goal on Adaptation, fossil fuel phase-outs, and climate finance.

The document outlines the challenges of researching climate obstruction in restrictive political environments, focusing on participant safety, data security, and the navigation of political 'red lines'. It recommends flexible research designs, such as using snowball sampling and reframing sensitive topics, to mitigate risks associated with government surveillance and data manipulation in non-democratic states.

The IRES project in Cuba is on track to achieve its expected results, though implementation of productive landscape modules is significantly behind schedule due to COVID-19, procurement delays, and fuel shortages. The project has successfully strengthened institutional capacities, improved governance, and contributed to national policy reforms. While it has a strong gender focus, the evaluation recommends moving toward a more gender-transformative approach to better capture and empower women's leadership and economic roles. The project is currently meeting its greenhouse gas emissions reduction targets, but requires improved monitoring and reporting capacities.

The research introduces a framework designed to address the limitations of climate adaptation strategies that are typically confined to local, national, or sectoral contexts. By providing typologies of cross-border impacts and responses, and defining actor configurations, the framework aims to facilitate systemic adaptation and cross-scale resilience. The authors tested this approach using a historical analysis of the 2010 food affordability crisis and a hypothetical future global food security crisis, concluding that the framework helps map policy gaps and informs the selection of governance approaches based on impact dynamics and coordination capacities.

The roadmap, developed following a 2023 science-policy dialogue with 45 regional stakeholders, provides 15 recommendations to address 'next generation' climate risks in the Hindu Kush Himalaya. These recommendations are categorized into research and knowledge sharing, policy and governance, and implementation, capacity strengthening, and finance, aiming to establish new channels and leverage existing entities for regional cooperation.

The research paper examines the critical role of women in climate mitigation across sectors like agriculture and energy, while highlighting systemic barriers such as limited land ownership and educational gaps. It advocates for feminist climate justice frameworks and gender-responsive policies, citing successful initiatives in Kenya, Nepal, Senegal, Southeast Asia, and Indonesia, and aligning these with global frameworks like the UNFCCC's Lima Work Programme on Gender.

RMI has launched the State CDR Atlas, a tool designed to help the 50 US states scale carbon dioxide removal (CDR) by assessing their unique geographies, infrastructure, and regulatory landscapes. The Atlas evaluates states across eight CDR approach categories using two primary ratings: an Opportunity Rating based on natural resources and infrastructure, and an Enabling Policy Rating based on the current regulatory environment. Using Virginia as a case study, the document illustrates how the tool identifies specific gaps—such as Virginia's lack of government procurement programs for CDR—and provides guidance on Terrestrial Enhanced Weathering (TEW) as a specific CDR approach. The tool is intended as an orientation and prioritization resource rather than a final siting mechanism.

The document clarifies that while COPs are often mandated to take 'any action necessary' to achieve treaty objectives, their power to act via decisions is limited. Decisions are typically suitable for guidance, budgeting, and coordination, but cannot fundamentally alter Party rights or obligations. Modifying obligations, creating new ones, or changing annexes generally requires formal amendments, which are subject to higher voting thresholds and lengthy ratification processes. The brief argues that relying on a general framework to be strengthened later via COP decisions is often ineffective, urging negotiators to secure strong provisions during the initial treaty adoption.

Canada has established a legal framework centered on the Canadian Net-Zero Emissions Accountability Act (2021), which mandates a binding process for setting emission targets and reporting progress. This system is supported by the 2030 Emissions Reduction Plan, carbon pricing via the Greenhouse Gas Pollution Pricing Act, and the creation of an independent Net Zero Advisory Body that integrates scientific and Indigenous knowledge.

The Lagos State Climate Adaptation and Resilience Plan (LCARP) identifies critical climate risks—sea-level rise, extreme rainfall, and extreme heat—and proposes a $9 billion portfolio of 33 projects to mitigate these threats. The plan emphasizes diversifying financing mechanisms beyond concessional debt to include blended finance, grants, and nature-based solutions, while recommending policy and governance reforms to attract private investment.

Chile has proposed that the Climate Science and Resilience Center (CR2) be admitted as an Associate of the Inter-American Institute for Global Change Research (IAI). The proposal highlights CR2's regional research ambitions in South America and Antarctica, its interdisciplinary approach to bridging natural and social sciences, and its contributions to Chilean public policy, including the 2022 Framework Law on Climate Change and the design of Chile's NDC for COP25. Additionally, CR2's leadership in climate services is noted through the creation of the Climate Risk Atlas of Chile (ARClim) and 14 other open-access climate services.

The IAI Science Diplomacy Center (SDC) is a regional initiative designed to foster science-policy dialogue and collaboration in the Americas, particularly Latin America and the Caribbean. Between 2023 and April 2024, the SDC established three priority pillars: Capacity Building, a Knowledge Hub, and Emerging/Evolving/Innovation Issues. Key achievements include the launch of a Science Diplomacy Training Program for Policy Makers, the expansion of the Science, Technology, and Policy (STeP) Fellowship program, and the development of a specialized science diplomacy curriculum with the University of Sao Paulo. The SDC is also building a Knowledge Hub to map experts, bibliography, and events, while engaging in strategic partnerships with organizations such as AAAS, UNESCO, and DiploCientifica to secure funding and expand regional training.

The proposal seeks USD 687,710 over 24 months to address five key barriers hindering Nicaragua's climate action: limited knowledge of GCF investment criteria, technical capacity gaps within the National Climate Change Management System (SNGCC), the absence of a long-term strategic roadmap, a lack of a scalable knowledge platform, and inadequate climate integration in educational curricula. The project, implemented by the Global Green Growth Institute (GGGI), will deliver training on project design, develop a National Climate Change Strategy Roadmap, update the NDC, and create an online educational platform for government officials, academia, and the private sector.
