The GCF Secretariat report for 2026 details progress in enhancing country ownership, delivering impact, and institutional strengthening. Key achievements include the launch of a revised Accreditation Framework, the establishment of regional presence in five locations, and the development of a new Commitment Authority Framework to optimize investment capacity. The report also tracks programming metrics, noting 29 funding proposals submitted to the iTAP and the approval of projects for underserved countries like Bahamas, Chad, and Jamaica.

The report examines how Vertical Climate and Environment Funds (VCEFs)—specifically the Green Climate Fund (GCF), Global Environment Facility (GEF), Climate Investment Funds (CIF), and Adaptation Fund (AF)—can better mobilize private climate finance for emerging markets and developing economies (EMDEs). It identifies three primary opportunities: implementing sequential financing to move projects from ideation to scale, increasing collaboration with the global network of public development banks (PDBs), and aligning funding with country-driven investment plans. The document emphasizes the need to address the high cost of capital in EMDEs to enable greater real-economy transformation as public climate finance becomes more constrained.

The global ocean economy reached USD 2.6 trillion in gross value added in 2020, yet investment in its sustainable transition remains critically low. While tracked ocean finance flows grew to USD 9.18 billion in 2023, this represents less than 2% of the estimated USD 550 billion needed annually by 2030. Financing is heavily reliant on official development assistance (ODA), which accounted for 55% of flows in 2023, but recent ODA cuts by major donors like Germany, the US, the UK, Japan, and France threaten progress. Most funding has historically targeted maritime transport, fisheries, and marine protection, while decarbonisation and adaptation sectors, such as offshore energy and disaster preparedness, remain underfunded. Despite this, investing in the ocean-climate nexus could reduce the 2050 emissions gap by 35% on a 1.5°C pathway and yield global benefits five times the value of the investment.

The project addresses the vulnerability of The Bahamas' water sector to hurricanes, storm surges, and sea level rise, which threaten the nation's primary natural freshwater source: shallow groundwater lenses. The proposal outlines a strategy to shift the national water utility, Water and Sewerage Corporation (WSC), away from a costly and financially unsustainable reliance on reverse osmosis (RO) desalination toward the sustainable use of climate-resilient groundwater. This will be achieved through three main outputs: strengthening national water policy and legislation, establishing a national water resources monitoring network and management unit (WRMU) with a decision support system (DSS), and implementing physical infrastructure upgrades across six priority islands. The project aims to benefit 415,000 people, with 215,273 receiving direct infrastructure improvements.

The report analyzes how GDP composition shifts from agriculture to services and manufacturing as countries grow wealthier. It highlights that while Africa's economic structure mirrors India's service-led growth, it lacks the broad industrial base seen in China's manufacturing-led strategy. The text notes that Africa's growth has been hindered by a reliance on extractive industries and a delayed demographic window of opportunity, expected around 2051.

The Latin America and Caribbean (LAC) region generates 19% of its electricity from wind and solar, exceeding the global average. While nearly half of the 33 LAC countries have pledged net-zero emissions by 2050, an implementation gap persists. The region possesses a third of global lithium, copper, and silver reserves, though investment has historically favored extraction over local manufacturing. Recent trends show a rise in electric vehicle sales and a shift in Venezuela toward solar generation to improve grid stability.

The document defines renewably powered minigrids (or microgrids) as systems combining renewable energy sources, battery storage, and sometimes backup generators to provide power to communities or specific facilities. It details three configurations: isolated, undergrid, and interconnected. Case studies illustrate their use in the Caribbean for hurricane resilience, in Africa for expanding business and home energy access, and in the United States for reducing diesel reliance in remote areas and enhancing military facility resilience.

Climate finance for emerging markets and developing economies (EMDEs) surpassed USD 1 trillion in 2023, with 80% mobilized domestically. Mitigation finance dominates, accounting for 92% of flows (USD 979 billion), while adaptation finance reached USD 48 billion. China is the primary driver, providing 64% of total EMDE flows. Significant gaps remain, with annual mitigation needs estimated at USD 3.86 trillion. The report recommends strengthening domestic enabling environments, improving the quality of international finance, and increasing data transparency to scale investment.

The report examines eight innovative financial instruments—including the Adaptation Benefit Mechanism, biodiversity credits, carbon taxes, carbon trading, credit guarantees, debt-for-nature/climate resilience swaps, pooled investment funds, and sovereign green/sustainability-linked bonds—to bridge the climate finance gap in developing countries. It identifies common barriers such as limited institutional capacity, lack of robust project pipelines, and underdeveloped local capital markets. The document emphasizes that while these instruments can signal a government's commitment to climate action, their success depends on a supportive enabling environment characterized by effective leadership, clear taxonomies, and robust climate data. For least developed countries (LDCs), the report suggests a phased approach, first strengthening basic financial and legal prerequisites before focusing on 'climate investability'. It concludes with specific recommendations for donors and development partners to provide technical assistance, anchor investments, and pilot projects to scale up private sector mobilization.

The report examines the limitations of rigid debt rules in emerging markets and developing economies (EMDEs), proposing a transition to a 'constrained discretion regime'. It argues that current rules-based approaches often lead to complexity and unenforceability, particularly when multiple fiscal rules are layered incrementally. The authors recommend replacing rigid ceilings with flexible 'debt anchors' embedded in a broader institutional framework featuring independent fiscal councils, transparent disclosure rules, and a clear distinction between long-term sustainability goals and short-term budgetary instruments.

The report identifies critical failure modes in ground-mount solar PV systems exposed to extreme winds, such as the failure of top-down clamps and low-cycle fatigue in module frames. It recommends high-load modules (4,000 Pa uplift), through-bolting with specialized washers, and dual-post foundation designs to improve survivability in hurricane-prone regions.

The report argues that the global ocean economy must transition from business-as-usual to a nature-positive model to avoid an estimated US$8.4 trillion in economic value loss by 2036. It introduces the AR3T (Avoid, Reduce, Restore & Regenerate, Transform) action framework to help companies in four key sectors—offshore wind, coastal and marine tourism, shipping, and seafood—halt and reverse biodiversity loss. The document emphasizes that nature positive is a collective societal goal, requiring absolute gains in nature rather than relative net gains or offsets. It provides specific technical recommendations for each sector, such as using nature-inclusive design in offshore wind, implementing sustainable siting in tourism, reducing vessel noise in shipping, and eliminating destructive fishing practices in the seafood sector. The report also highlights the necessity of integrating social equity and Indigenous knowledge into conservation efforts, asserting that a nature-positive future must also be 'people positive'.

The IMO's new Net-Zero Framework is criticized as a 'defeat for the climate' because it replaces a universal carbon levy with a hybrid fuel standard and weak carbon pricing. The author contends that the scheme will only reduce emissions by about 10% by 2030—half of the IMO's own base target—and will generate insufficient revenue ($11-12 billion annually) to support the transition to zero-emission fuels, which requires $12-24 billion per year.

The report identifies a critical need to accelerate the integration of health and climate policies in the Caribbean to address climatic vulnerability and a dual burden of non-communicable and infectious diseases. While there is general support for this integration, current links remain nascent and tenuous. Key barriers include siloed government operations, a rigid top-down policymaking process, inadequate financial and technical resources, and significant data gaps. Opportunities for progress lie in national development plans, international climate commitments, and the health co-benefits of renewable energy. The authors advocate for a 'climate in all policies' approach, enhanced multi-sectoral communication, and the use of analytical risk assessment tools to move from awareness to decisive policy action.

The document explains that climate-resilient debt clauses (CRDCs) are contractual agreements that allow countries to temporarily postpone debt repayments following natural disasters, providing essential liquidity for emergency response. It details the design of these instruments—including parametric and proxy triggers—and discusses their adoption by Caribbean small island developing states and various multilateral development banks. The guide highlights challenges such as trigger identification and portfolio risk for regional banks, while providing a decision tree to help development finance institutions assess the feasibility of offering CRDCs.

The document explains climate-resilient debt clauses (CRDCs) as contractual tools that allow countries to postpone debt repayments following natural disasters, thereby creating fiscal space for emergency response. It details the technical design of these clauses, including triggers and deferral terms, and analyzes the implications for multilateral development banks (MDBs) and public development banks (PDBs). The primer highlights the role of the ICMA Term Sheet in standardization and provides a decision tree to help financial institutions assess the feasibility of adopting CRDCs based on liquidity, regulatory environment, and disaster risk management systems.

The 2025 Impact Report details the Fossil Fuel Treaty Initiative's progress in securing diplomatic support, engaging subnational governments, and conducting research to create a 1.5ºC-aligned mechanism for phasing out fossil fuels. Key achievements include the announcement of the First International Conference on Transitioning Away from Fossil Fuels for April 2026, the addition of Cambodia and Saint Kitts and Nevis to the participating nations, and a resolution in support of the treaty passed by the IUCN. The initiative has grown to include 18 participating countries from the Global South, over 140 cities, and 4,200 civil society organizations.

The report argues that a Fossil Fuel Non-Proliferation Treaty can catalyze the financing necessary for a global just transition by establishing new funding regimes, creating state obligations, and supporting parallel financial reforms. It categorizes potential solutions into three clusters: debt management, new forms of finance and investment, and the replacement of fossil fuel revenues. The authors emphasize that wealthy nations must assume historical responsibility by ending extraction first and providing financial support to low and middle-income countries (LMICs) to diversify their economies.

Carbon Market Watch (CMW) assessed several market-based proposals for international shipping decarbonization, scoring them based on alignment with the 1.5°C Paris Agreement goal, emission reductions, and equity. The analysis highlights that while the IMO's 2023 strategy aims for net-zero emissions by 2050, current measures are insufficient. CMW identifies the proposal by Canada as the strongest (Score A+), citing its high carbon levy of 150 $/tCO2e, while criticizing the Bahamas et al. proposal (Score C) for its reliance on a flexibility compliance mechanism that disincentivizes decarbonization.

Carbon Market Watch (CMW) assessed several market-based measure (MBM) proposals for the international shipping sector, using a methodology developed by CE Delft. The evaluation focused on alignment with the Paris Agreement's 1.5°C goal, immediate emission reductions, support for vulnerable nations and workers, and funding for research and development. The analysis highlights that current IMO strategies are insufficient for 1.5°C alignment and that only proposals with high carbon levies—such as those from Canada and Austria et al.—provide a strong enough price signal to drive the transition to zero-emission technologies.
