This report analyzes adaptation finance for Small Island Developing States (SIDS), finding that current annual flows of just over USD 2 billion (0.2% of global climate finance) must increase six-fold to USD 12 billion to meet assessed needs. It highlights that 44% of this finance is debt-based, funding is highly concentrated among 10 SIDS, and there is a significant disparity between ODA-eligible and ODA-ineligible nations. The authors call for increased grants, a shift toward a multidimensional vulnerability index for eligibility, and improved tracking of both public and private finance.

A 'Call to Action' issued on 12 March 2025 by Government Representatives of Small Island Developing States (SIDS) meeting in Bridgetown, Barbados. The document outlines the urgent need for a just energy transition in SIDS to reduce fossil fuel dependency, address climate vulnerabilities, and increase energy access through five key areas of action: strengthening commitments, mobilizing finance, enhancing regional platforms, augmenting institutional capacity, and improving resilience and innovation.

This briefing summarizes two 2024 IPBES assessments, highlighting that over half of global GDP (USD 58 trillion) depends on nature, yet financial systems continue to prioritize harmful activities. While USD 7 trillion is invested annually in biodiversity-damaging activities and subsidies for such sectors reach up to USD 3.3 trillion, biodiversity conservation receives only USD 135-200 billion. The reports argue for a systemic transformation—including pricing externalities, reforming debt for low-income nations, and closing a funding gap of up to USD 1 trillion per year—which could potentially create USD 10 trillion in business value and 395 million jobs by 2030.

This executive summary, published by the Stockholm Environment Institute (SEI) in 2024, provides recommendations for the operationalization of the Loss and Damage Fund established at COP27. Based on consultations with stakeholders from the Global South, the document advocates for a participatory governance structure, direct access for local communities, and a comprehensive funding approach that addresses both economic and non-economic losses while prioritizing human rights and dignity.

This report by the Rocky Mountain Institute (RMI), in partnership with the Clinton Climate Initiative and UN-OHRLLS, provides policymakers in Small Island Developing States (SIDS) with best practices to increase the resilience of solar photovoltaic (PV) systems against extreme wind events. Based on field evaluations of failures and successes following hurricanes in the Caribbean and Pacific, the document outlines technical specifications for ground-mount and rooftop systems and emphasizes the need for multi-stakeholder collaboration to ensure infrastructure survives Category 5 storms.

This research paper by the Stockholm Environment Institute analyzes development finance for energy sectors in 37 Small Island Developing States (SIDS) between 2002 and 2016, utilizing data from the OECD Development Assistance Committee and the World Bank.

This policy brief examines the role of micro-insurance as a climate change adaptation strategy for Small Island Developing States (SIDS), specifically targeting low-income coastal communities in sectors like tourism, fisheries, and agriculture where traditional insurance is often non-existent or inaccessible.

This briefing, published by the Climate and Development Knowledge Network in 2014, distils the findings of the IPCC's Fifth Assessment Report specifically for Small Island Developing States (SIDS). It outlines the observed and projected impacts of climate change on SIDS, including sea level rise, temperature increases, and the degradation of critical ecosystems like coral reefs. The document discusses the high economic costs of adaptation relative to SIDS' GDP, the risks of 'maladaptation', and the necessity of international cooperation and finance to avert existential threats to atoll nations.

This précis outlines the implications of the United Nations Secretary’s High-Level Advisory Group on Climate Finance (AGF) recommendations for Small Island Developing States (SIDS), focusing on the goal of raising US$100 billion per year for climate change investment in developing countries by 2020.

This briefing, written by Vivid Economics and funded by the Climate and Development Knowledge Network (CDKN), analyzes the implications of the Advisory Group on Climate Finance (AGF) recommendations for Small Island Developing States (SIDS). It evaluates the investment needs for adaptation and mitigation in SIDS, the potential for public and private funding sources, and the specific risks and opportunities these financial mechanisms present for island nations.

This policy submission by the International Institute for Sustainable Development (IISD) examines the challenges of aid delivery to Small Island Developing States (SIDS). It argues that while per capita aid is often higher for SIDS than for mainland developing countries, overall aid levels declined by over 50 percent between 1994 and 2004. The document proposes eight reforms to make aid more effective, including untying aid from donor procurement, harmonising policies across donors, and replacing GDP-per-capita assessments with vulnerability indices.

This report summarizes a workshop held during COP19 as part of the Many Strong Voices (MSV) Programme. The dialogue focused on the challenges of climate-induced community-based relocation, specifically in the Arctic and Small Island Developing States (SIDS), emphasizing the need for participatory decision-making, international finance, and the protection of human rights and cultural identity.

This report by the Climate Policy Initiative and the Global Center on Adaptation analyzes international public climate adaptation finance for Small Island Developing States (SIDS) between 2021 and 2022. It identifies a significant funding gap, noting that current annual flows of approximately $2 billion are far below the estimated annual need of $11.7 billion. The report highlights that a large portion of this finance is provided as debt, posing macroeconomic risks, and calls for a shift from GNI-based ODA eligibility to a multidimensional vulnerability index to improve financial access.

This executive summary synthesises three reports from the Ocean Risk and Resilience Action Alliance (ORRAA) regarding the 'Blue Acceleration'—the rapid expansion of ocean-based industries. It highlights the systemic inequities of this growth, noting that benefits primarily flow to powerful states and corporations while Small Island Developing States (SIDS) and Least Developed Countries (LDCs) face disproportionate risks. The document emphasizes the need for multidimensional risk assessments, the integration of local and indigenous knowledge, and gender-transformative approaches to ensure an equitable and resilient ocean economy.
