New Index Ranks Vulnerabilities of 188 Nations to Climate Shocks

or at high risk of entering debt distress. The African nations that appear in the bottom 10 across the four climate scenarios are: Angola, Burundi, The Gambia, Guinea-Bissau, Eritrea, Lesotho, Malawi, South Sudan, Sudan, and Zambia.
 There are six nations in the Asia-Pacific region that appear in the Red Zone, and they are home to more than 520 million people. In 2024, the WMO termed Asia the "world's most disaster-hit region from weather, climate and water-related hazards." The six nations are: Bangladesh, Kiribati, Myanmar, Nepal, Pakistan, and Sri Lanka.
 Latin America and the Caribbean (LAC) are home to eight Red Zone nations and more than 100 million people. The LAC region is vulnerable to climate change and requires investment of between $470 million and $1.3 trillion to deliver on the Paris Agreement goals, according to the Inter-American Development Bank. Of the eight LAC nations that appear in the Red Zone, seven do so across all four climate scenarios. The eight nations are: Belize, Bolivia, Ecuador, El Salvador, Guatemala, Haiti, Honduras, and Venezuela.
 Just two European nations appear in the Red Zone. The two nations, which are home to 39 million people, are Ukraine and Cyprus. Cyprus appears in the 2050 optimistic, 2050 pessimistic, and 2080 pessimistic scenarios. Ukraine appears in 2050 optimistic and 2080 optimistic scenarios.
 Across all four climate scenarios, eight of the 10 nations best positioned to respond are OECD members. They are Denmark, Estonia, Japan, Norway, South Korea, Switzerland, Sweden and United States. Non-OECD members to appear in the top 10 are China, Thailand and United Arab Emirates (UAE). China appears across all four climate scenarios, Thailand appears in the 2050 optimistic and 2080 optimistic scenarios, and UAE in the 2050 pessimistic and 2080 pessimistic.

Developed by an interdisciplinary team from the National Center for Disaster Preparedness, based at the Columbia Climate School, and the Center for Global Energy Policy, at Columbia University's School of International and Public Affairs and also an affiliate center of the Columbia Climate School, the CliF Vulnerability Index integrates data on debt sustainability, financial integration and sophistication, and governance considerations that influence lending conditions.

Statements of Support

"The CliF Vulnerability Index is an excellent tool and guides the effectives of climate finance measures for countries facing fiscal risks and fiscal space constraints as a result of climate change. The tool talks to the African Climate Foundation's own work on adaptation and resilience investment platforms where we are looking to adopt more systemic approaches to adaptation in Africa for countries suffering by high debt distress and by tackling the problem of climate risk head on through more robust fiscal measures we hope to find innovate ways to bring fiscal relief." ? Saliem Fakir, Executive Director, The African Climate Foundation
 "Addressing child poverty globally requires us to work collectively to get the right kinds of finance to the right places, at a much greater scale. In particular, countries with the greatest vulnerability to climate and financial shocks require the greatest support to ensure effective investment is flowing to child health, nutrition and resilient communities – the CliF Vulnerability Index plays a key role in ensuring critical decisions can be made in a transparent, data driven way." ? Michael Hugman, Lead Economist & Global Climate Director, Children's Investment Fund Foundation 
  "Africa is on the frontline of the climate change's impact, bearing the brunt despite contributing the least. With 43 of the 65 most vulnerable nations in the Red Zone located in Sub-Saharan Africa, we face a dire threat compounded by a severe lack of funding. The CliF Vulnerability Index is a game-changer, illuminating the urgent need to prioritize financing for Africa. We need this capital flowing immediately to build resilience, foster green growth, and truly champion climate-smart development, for Africa's future and the world." ? William Asiko, Vice President, Africa Regional Office, The Rockefeller Foundation
 "We are witnessing a meaningful shift across Asia in the way countries access and deploy climate finance. Countries like India and Thailand are taking a leadership role that offers a pathway for others in the region to emulate. The CliF Vulnerability Index highlights both vulnerabilities and the subsequent financial opportunity, giving governments and donors a clearer view of the investment landscape. This is crucial as climate impacts intensify and funding gaps continue to grow, even in the countries that are performing well. By offering a more comprehensive picture of risk and readiness, The Index will help countries move forward with greater clarity, intention, and purpose to mitigate and adapt to climate change." — Deepali Khanna, Vice President, Asia Regional Office, The Rockefeller Foundation
  "The CliF Vulnerability Index highlights the risks facing millions of people living in the Latin America and the Caribbean region. This tool comes at a key moment when donors and investors need help understanding and prioritizing resources." ? Lyana Latorre, Vice President, Latin America and the Caribbean Regional Office, The Rockefeller Foundation
