NETHERLANDS / RankWire.AI / – According to an analysis by Triodos Bank, intense heatwaves and drought conditions across Europe have the potential to shave off approximately 1% from the European Union’s economic output in 2026. This estimated decrease amounts to about €180 billion, occurring amid a year already marked by sluggish growth. The European Commission predicted in May that the EU’s gross domestic product would expand by 1.1% in 2026. This baseline projection leaves little room between anticipated growth and the economic damage projected from this summer’s extreme weather events.
The primary driver of the projected losses is reduced worker productivity during heatwaves, accounting for roughly 0.6% of EU GDP. Agriculture also faces significant challenges following prolonged periods of high temperatures and dry spells across key farming regions. The assessment estimates agricultural output could decline between 3% and 7%. Additionally, disruptions to energy production, transport networks, and logistics further contribute to the overall economic impact, as elevated temperatures and lowered water levels interfere with normal operations.
This summer, Western Europe experienced extraordinary heat levels. Copernicus reported that June and July together marked the region’s warmest period on record, with an average temperature of 21.62°C, which is 2.79°C above the 1991-2020 average. July also saw widespread dryness across much of western and central Europe, with parts of France, Germany, Austria, Hungary, and the Iberian Peninsula recording their lowest soil moisture levels since at least 1979.
France Faces the Most Significant GDP Reduction
France is expected to experience the largest national impact, with heat and drought potentially reducing its GDP growth by approximately 1.4 percentage points in 2026. This scenario suggests that French economic output may contract by around 0.6%. Italy and Spain are also among the more vulnerable major economies, while Belgium is likely to face notable effects. The Netherlands could see a decrease of about 0.8 percentage points in growth, resulting in an overall flat economic activity for the year.
This heat-related forecast coincides with Europe’s ongoing economic slowdown, with EU growth reaching 1.5% in 2025 and a projected slowdown for 2026. The Commission’s spring outlook estimated that the euro area would grow by 0.9% this year. Severe weather conditions place additional strain on the economy through lost work hours, diminished agricultural yields, and infrastructure disruptions. These impacts can ripple across sectors, especially when low river levels hinder transportation or high temperatures reduce electricity generation and industrial efficiency.
Extreme Climate Conditions Impact Food and Industrial Output
Research indicates that extreme heat is linked to rising food prices and declining corporate performance. The European Central Bank found that the 2025 summer heatwave added between 0.4 and 0.7 percentage points to euro area unprocessed food prices after one year. Separate research at the firm level in Italy revealed that intense heat reduced company sales by approximately 0.8%. Days with temperatures exceeding 40°C also caused notable losses in production and productivity, according to that analysis.
The 2026 assessment emphasizes the immediate economic consequences of this summer’s heat and drought, rather than projecting long-term climate impacts. Its estimated 1% reduction in EU GDP closely aligns with the 1.1% growth forecast for the year. The most significant source of losses stems from decreased labor productivity, with agriculture, energy, and transport sectors adding further costs. Given that western Europe experienced extraordinary heat and widespread soil moisture deficits, these figures highlight how severe weather events are becoming a tangible factor in the EU’s economic outlook for 2026.
