Climate-Fuelled Damage Costs Caribbean $53bn, Study Finds 2026

Climate-fuelled damage has cost Caribbean nations $53.2bn between 2000 and 2024, according to a new study by ODI Global. This staggering figure represents over 90% of the total $57bn in economic losses across 39 developing island nations, highlighting the disproportionate burden borne by the Caribbean in the global climate crisis.

Caribbean Bears the Brunt of Climate-Fuelled Damage

The research, published on Wednesday, analyzed floods, storms, and drought across the Caribbean, Pacific, Atlantic, Indian Ocean, and South China Sea. It found that the Caribbean alone suffered $53.2bn in damages—more than nine-tenths of the total. The study also estimates that climate change caused over 190 deaths per year across these island nations during the 25-year period.

Emily Wilkinson, the report's author, emphasized the importance of this data for climate reparations discussions. "There have always been hurricanes, heavy rainfall, drought and temperature extremes, historically, but it's really important to be able to say what percentage of that kind of strength or intensity is actually due to increasing global temperatures," she said.

Attribution Science and Climate Justice

Wilkinson explained that climate scientists use attribution studies to determine how much of an event's intensity is due to climate change. ODI Global went further by calculating the fraction of attributable risk to estimate the percentage of reported damage caused by climate change. This approach strengthens the case for compensation from high-emitting nations.

Several Caribbean countries have already provided evidence to the International Court of Justice, which issued a landmark advisory opinion in 2024. That opinion could compel states to pay reparations if they fail to curb fossil fuel emissions and prevent harm to the climate system.

Key Findings from the ODI Global Report

• The Caribbean suffered $53.2bn in climate-fuelled damage from 2000 to 2024.
• Total damage across all 39 developing island nations reached $57bn.
• Climate change caused over 190 deaths annually in these regions.
• The Caribbean accounts for more than 90% of total economic losses.
• The report supports climate reparations claims against major emitters.

Comparison of Regional Climate Damage

This disparity underscores the Caribbean's unique vulnerability to hurricanes and sea-level rise, driven by warming oceans. The report calls for urgent global action to address climate financing and loss-and-damage mechanisms.

Implications for Climate Reparations

The findings are critical for ongoing negotiations on climate reparations. Developing island nations have long argued that they contribute least to greenhouse gas emissions yet suffer the most severe consequences. The ODI Global report provides concrete evidence to support their demands for financial assistance from wealthy, high-emitting countries.

Wilkinson noted that attribution studies are "really important for when we start to think about responsibilities for the impacts of climate change, compensation and climate reparation." The report adds a new layer of accountability by quantifying the climate-driven portion of damages.

FAQ

As the world grapples with climate change, this study serves as a stark reminder of the unequal burden borne by small island developing states. It strengthens the moral and legal case for climate reparations, urging global leaders to act on their promises.
