The document examines the critical water crisis in El Alto and La Paz, Bolivia, where rapid population growth and climate-driven glacier retreat are reducing water supplies. Using the Water Evaluation and Planning (WEAP) tool, the Stockholm Environment Institute identifies that current systems are highly vulnerable, with the El Alto system predicted to fail almost permanently between 2011 and 2030. The briefing recommends a combination of new reservoir construction (such as Khotia Khota and Kaluyo), significant reductions in urban and agricultural water leaks, and improved industrial wastewater recycling to build resilience. It emphasizes the need for watershed-based coordination and community participation in planning to manage the projected population increase to two million people in El Alto by 2050.

The paper argues that private-sector finance is an unreliable primary source for climate adaptation in developing countries due to historical patterns of uneven distribution across regions and sectors. Analysis shows that investment is heavily concentrated in major emerging economies, while Least Developed Countries (LDCs) and critical adaptation sectors like water and small-scale agriculture are largely neglected. The author cautions that the private sector's historical failure to alleviate poverty in the poorest regions suggests it may not naturally address the most pressing adaptation challenges without significant public finance intervention and more rigorous accounting of actual outcomes.

The research examines historical private capital flows—including foreign direct investment (FDI), portfolio equity, and bank lending—to assess their suitability for climate adaptation in developing countries. It finds that private finance is heavily concentrated in a few emerging economies and resource-extraction sectors, often bypassing the Least Developed Countries (LDCs) and critical adaptation sectors like water and small-scale agriculture. The author argues that the unpredictability and sectoral bias of private investment pose significant challenges for the delivery of the USD 100 billion annual climate finance pledge, suggesting that public finance must fill these gaps rather than simply attempting to leverage private flows that naturally avoid the most vulnerable areas.

The document evaluates the 2009 OECD checklist on private sector participation in water infrastructure. It acknowledges positive additions regarding responsible business conduct and sustainability but criticizes the checklist for contradictions regarding decentralization, a perfunctory treatment of international investment arbitration risks, and the omission of the 'duty of efficiency' as a legal requirement for providers.

The document reports that pastoral communities in Ethiopia's Borana and Somali zones are facing unprecedented climate variability, including increasing temperatures and drought frequency, which are rendering traditional coping strategies ineffective. It identifies significant barriers to adaptation, such as land degradation, resource conflicts, and limited access to information and financial services. The brief recommends that the Ethiopian government protect pastoral land, improve weather information sharing, and enhance social safety nets. It advises civil society to integrate climate projections into programming and leverage traditional knowledge, while urging international donors to provide funding flexibility for climate emergencies.

The document presents a method for analysing water-related poverty by integrating the Sustainable Livelihoods (SL) framework with Bayesian networks (BNs). This approach addresses the 'fuzziness' of livelihood systems—caused by variability, diversity, and uncertainty—by using probability distributions rather than fixed values. The authors introduce a novel way to represent institutions as 'categorical inequality' (e.g., gender) and a 'latent variable' method where indicators serve as indirect evidence for assets rather than direct proxies. The model was applied to data from Si Sa Ket province in Northeast Thailand, demonstrating that locally-originated water supply schemes, such as water tanks and drill wells, can be more effective for poor households than unreliable large-scale irrigation projects.

The Borough of Dolphin Coast municipality engaged the private sector, via a deal involving SAUR Services and Siza, to upgrade failing water and sanitation infrastructure. While targets were met in wealthier areas, poorer areas suffered from unmet targets and tariff increases, contributing to 140 cholera cases in the first year. The concession faced financial instability by 2001, necessitating contract adjustments that reduced municipal fees and investment commitments while raising consumer prices.

The document assesses the relationship between international investment agreements (IIAs) and the Millennium Development Goals (MDGs). It finds that while IIAs may attract foreign direct investment (FDI) and potentially foster economic growth, these benefits are uncertain and depend on domestic institutional capacity. Conversely, the paper identifies several systemic risks where IIA provisions—specifically those regarding expropriation, national treatment, and prohibitions on capital controls and performance requirements—may conflict with public health, environmental sustainability, and poverty alleviation efforts.

The report examines future water requirements through a 'Conventional Development Scenario' (CDS), which assumes a continuation of current demographic and economic trends. It finds that global water withdrawals are projected to increase from 3,700 cubic kilometers in 1995 to 5,000 cubic kilometers by 2025 in a mid-range case, with the most significant growth in developing regions. The study introduces several indices—including use-to-resource ratio, reliability, and coping capacity—to map water vulnerability. Results indicate that by 2025, a substantial portion of the world's population will live in water-stressed conditions, particularly in Asia, North Africa, and the Middle East. The report argues that this 'business-as-usual' path is unsustainable and proposes a transition toward a sustainable water future based on efficiency, equity, and ecosystem protection.

The report presents four narrative scenarios for the future of U.S. municipal water systems in 2010, structured around two critical uncertainties: the extent of the federal government's regulatory and managerial role and the availability and cost of capital. The scenarios—'Mandate', 'Approaching Apocalypse', 'Seeking Camelot', and 'Off to Market'—explore how different combinations of these drivers, alongside factors like public health concerns, technological advances, and demographic shifts, could shape water infrastructure, quality, and management. The document emphasizes that these are not predictions but tools to help water managers and policymakers identify risks and develop robust strategies.

The document describes CCORAL, a Caribbean-specific tool used to screen policies, legislation, plans, budgets, and projects for climate risks. It outlines a three-step process involving basic screening questions, a detailed vulnerability workbook, and risk management analyses. The briefing specifically details how CCORAL applies to the water sector, including water policies, legislation, supply plans, financial budgeting, and infrastructure projects, noting that the tool is designed for use by both climate specialists and non-specialists.

The document argues that achieving water security in Africa requires tens of billions of dollars annually, with climate resilience adding an additional US$10–15 billion. It suggests a blended financing approach combining traditional water finance, official development assistance, and specialized climate finance to bridge the funding gap. While most climate finance currently targets mitigation, the briefing emphasizes the need for adaptation funding and the role of the Green Climate Fund in supporting African water infrastructure.

The green bond market experienced rapid growth between 2013 and 2016, with total emissions reaching USD 81 billion in 2016. The market is increasingly dominated by the private sector, with corporate and bank emissions rising from less than 1% in 2010 to 66% in 2016. While mitigation projects—specifically clean energy, energy efficiency, and low-carbon transport—receive approximately 75% of funds, financing for adaptation grew from less than 1% in 2011 to 5% of total emissions, driven largely by US municipalities. China emerged as a leading market, projecting to be the largest globally. To support the Paris Agreement, the Climate Bonds Initiative targets annual green bond emissions of USD 1 trillion by 2020. The document recommends that governments implement national capital mobilization plans, apply international standards like the Green Bond Principles and Climate Bonds Standard, and develop national verifier networks to reduce market friction and prevent greenwashing.

The Climate Bonds Standard and Certification Scheme provides a globally recognised framework for labelling debt instruments, assets, and entities aligned with a 1.5°C pathway. Since 2012, it has certified over USD350bn of Use of Proceeds Green Bonds as of 30 September 2025. The scheme utilizes a network of Approved Verifiers to ensure climate integrity across various certification types, including Use of Proceeds, Asset, Entity, and Sustainability-linked debt. A 2025 update expanded the standard to include a Resilience Taxonomy for projects strengthening resilience to physical climate risks. Eligible sectors span energy, industry, transport, agrifood, and infrastructure.

The Climate Bonds Standard Version 3.0 provides a framework for certifying bonds that fund climate-aligned projects. It aligns with the Green Bond Principles and requires issuers to meet pre-issuance and post-issuance criteria regarding the use of proceeds, project selection, and reporting. Certification is overseen by the Climate Bonds Standard Board and requires independent verification. The standard utilizes a Taxonomy of Green Definitions and sector-specific technical criteria to determine project eligibility, covering areas such as solar, wind, and low carbon buildings.

The Climate Bonds Standard provides a framework for certifying 'green' bonds, ensuring funds are used for climate-aligned projects. It defines pre- and post-issuance requirements, a two-step eligibility process involving a taxonomy and sector-specific technical criteria, and a certification process overseen by an independent board and verified by third-party auditors.

The report argues that the Safe Drinking Water Act (SDWA) has transitioned from an 'outstanding' to an 'outdated' framework due to 1996 amendments that slowed the regulation of new contaminants and a chronic lack of federal infrastructure funding. It highlights critical failures in monitoring and sampling protocols, which allow water systems to use infrequent or misleading tests, and criticizes the lack of transparency in Consumer Confidence Reports. The document emphasizes that low-income, Black, and Indigenous communities disproportionately suffer from these weaknesses. A case study of the Red Hill Bulk Fuel Storage Facility in O‘ahu illustrates how the SDWA failed to detect and report jet fuel and PFAS contamination. Earthjustice calls for a modernized SDWA with streamlined chemical regulation, advanced monitoring technology, and at least $20 billion in annual federal funding.

The report provides a comprehensive list of public laws from 2017 to 2022 that address climate adaptation, focusing heavily on national security, disaster relief, and infrastructure resilience. Key legislative trends include the integration of climate risk into Department of Defense (DoD) planning, the expansion of pre-disaster mitigation funding through the Disaster Recovery Reform Act and the Infrastructure Investment and Jobs Act, and targeted conservation efforts for forests, wetlands, and the Arctic. The document details specific mandates for flood mapping, sea-level rise projections for military installations, and the creation of specialized funds for community resilience and drought management.

The State Revolving Loan Funds (SRFs) operate as finance programs where federal grants are converted into loans for local utilities, which are then repaid and reinvested. The Clean Water SRF (CWSRF) and Drinking Water SRF (DWSRF) provide below-market interest rates (averaging 1.5%) and prioritize projects based on state-specific needs, including green infrastructure and disadvantaged communities. Since 1988, the CWSRF has facilitated over $172 billion in investment across 65,000 projects. The document highlights a critical funding gap, noting that the national need to maintain clean water infrastructure is at least $630.1 billion over the next twenty years.

The document outlines mandatory conditions and recommendations for multiple GCF funding proposals across various countries. General conditions for all proposals include the signing of a funded activity agreement (FAA) and completion of legal due diligence. Specific conditions target projects in Afghanistan (mini-grid market governance), Colombia (REDD+ emission reductions), Ghana (sustainability of shea landscapes), Sudan (conflict analysis and water infrastructure), and others. Recommendations from the independent Technical Advisory Panel (TAP) focus on quality assurance in Indonesia, policy advocacy in Nepal, and gender-inclusive decision-making in Sudan.
