AMSTERDAM, Aug. 13, 2026 – Extreme heat, drought and related disruptions could reduce European Union economic output by roughly €180 billion this year, equivalent to about 1% of the bloc’s gross domestic product, according to an assessment published on Thursday by Dutch sustainable banking group Triodos Bank.
The estimate comes as large parts of Europe continue to experience prolonged high temperatures, dry soils, low river levels and elevated wildfire risks. Triodos said the economic toll is spreading beyond agriculture to affect transport, energy generation and labour productivity.
Productivity losses weigh on output
In a report shared with Reuters, Triodos calculated that heat induced productivity losses alone could shave about 0.6% off EU economic output. Extreme heat can impair physical and cognitive performance, especially in outdoor sectors such as construction, agriculture and logistics, while employers may be forced to introduce extra rest breaks and other protective measures for workers, the bank said.
Agriculture remains highly exposed to heat and water shortages, which can cut crop yields, harm livestock and push up food production costs.
France seen among most vulnerable
France is among the member states facing a relatively large potential hit. Triodos estimated that recurring heatwaves could reduce French economic growth by about 1.4 percentage points under its modelling assumptions. The bank stressed that this is not a forecast of an actual contraction, but rather a scenario based illustration of possible heat related losses.
Low water levels disrupt transport and energy
Low water levels on key inland waterways are adding to the strain. The Rhine and Danube rivers serve as major arteries for industrial commodities, agricultural goods and energy related freight. Reduced draft capacity can force vessels to carry lighter loads, raise shipping costs and cause delivery delays, Triodos noted.
At the same time, extreme heat tends to boost electricity demand for cooling while lowering the efficiency of thermal power generation. Drought can also curtail hydropower production and restrict cooling water availability for some industrial plants and power stations.
Modest growth provides limited buffer
The potential losses come at a time when Europe’s economic expansion remains subdued. The European Commission has forecast EU GDP growth of 1.1% in 2026, with the euro area projected at 0.9%. The European Central Bank and the International Monetary Fund have各自 estimated euro area growth at 0.8% and 0.9%, respectively. Against that backdrop of relatively low growth, a severe weather related shock could have a discernible impact on annual economic performance, Triodos said.
Climate risks translate into financial risks
The Triodos assessment illustrates how extreme weather can propagate through interconnected economic systems – affecting food production, labour productivity, energy markets, logistics and industrial supply chains simultaneously.
The €180 billion figure is an estimate based on the bank’s assumptions and current weather patterns, not a definitive projection. The final economic cost will hinge on the duration and geographic spread of the extreme conditions, subsequent weather developments, market adjustments and the adaptive capacity of businesses and governments.
For European policymakers, the broader question is how to strengthen economic resilience as extreme weather events become an increasingly systemic risk to productivity and growth. Triodos said it would continue to monitor the situation and update its analysis as new data become available.
