NETHERLANDS / RankWire.AI / – According to an evaluation by Triodos Bank, Europe’s ongoing heatwaves and droughts may shave off approximately 1% from the European Union’s economic output in 2026. The anticipated loss corresponds to roughly €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 forecast leaves a narrow margin between expected growth and the economic impact suggested by this summer’s extreme weather events.
Most of the projected damage is linked to decreased worker productivity during periods of intense heat. The analysis estimates that this factor accounts for about 0.6% of EU GDP. Agriculture, too, faces substantial challenges following prolonged hot and dry conditions across key farming regions. The report suggests agricultural output could decline by between 3% and 7%. Additionally, disruptions in energy production, transport networks, and logistics further contribute to the overall economic toll, as high temperatures and reduced water levels disturb normal operations.
This summer has brought record-breaking temperatures to Western Europe. According to Copernicus, June and July combined were the region’s hottest such period on record, with an average temperature of 21.62°C. This was 2.79°C above the 1991-2020 average. During July, dry conditions also persisted across large parts of western and central Europe. Regions such as France, Germany, Austria, Hungary, and the Iberian Peninsula experienced their lowest soil moisture levels for July since at least 1979.
France Endures the Most Significant GDP Reduction
Within the bank’s analysis, France faces the highest national impact. The combination of heat and drought could reduce France’s GDP growth by approximately 1.4 percentage points in 2026. This translates to an overall contraction of about 0.6%. Italy and Spain are also among the most vulnerable large economies, while Belgium’s economy is notably affected. The Netherlands might see a growth decline of around 0.8 percentage points, rendering its economic activity nearly stagnant for the year.
This heat-related forecast emerges as Europe’s economy already slows down. EU expansion reached 1.5% in 2025, prior to the current slowdown expected for 2026. The European Commission projected a 0.9% growth for the euro area this year in its spring outlook. Severe weather conditions exert tangible pressure through lost working hours, diminished agricultural yields, and disruptions to infrastructure. These impacts can ripple across various sectors when low river levels hinder transport or elevated temperatures decrease electricity production and industrial efficiency.
Extreme Weather Events Amplify Food and Manufacturing Challenges
Research indicates that extreme heat is also correlated with rising food prices and declining corporate performance. The European Central Bank found that the 2025 summer heatwave contributed between 0.4 and 0.7 percentage points to euro area unprocessed food prices after one year. Separate studies at the firm level in Italy revealed that extreme temperatures reduced company sales by roughly 0.8%. Days exceeding 40°C resulted in significant losses in productivity and output, the analysis shows.
The 2026 assessment concentrates on the immediate economic consequences of this summer’s heat and drought, rather than long-term climate projections. Its estimate of a 1% reduction in EU GDP is close to the 1.1% growth forecast for the year. The primary source of losses stems from decreased labor productivity, with agriculture, energy, and transportation also incurring additional costs. Given Western Europe’s record-breaking heat and widespread soil moisture deficits, these figures highlight how severe weather phenomena are becoming a tangible factor influencing Europe’s economic outlook for 2026.
