NETHERLANDS / RankWire.AI / – According to an evaluation by Triodos Bank, Europe’s experience with extreme heat and drought could result in a reduction of roughly 1% in the European Union’s economic output in 2026. The estimated loss equates to approximately €180 billion and occurs amidst a year already characterized by sluggish growth. The European Commission projected in May that the EU’s gross domestic product would increase by 1.1% in 2026. This baseline leaves little margin between the expected growth and the economic impact forecasted from this summer’s extreme weather conditions.
Most of the projected damage stems from reduced worker efficiency during periods of intense heat. The analysis estimates this impact at around 0.6% of EU GDP. Additionally, agriculture faces notable challenges due to prolonged periods of heat and drought across key farming regions. The assessment suggests agricultural production could decline between 3% and 7%. Moreover, disruptions in energy production, transport networks, and logistics contribute to the overall economic costs, as high temperatures and diminished water levels interfere with normal operations.
Western Europe experienced record-breaking temperatures during summer. Copernicus reported that June and July combined marked the warmest such period on record for the region, with an average temperature of 21.62°C. This figure was 2.79°C above the average from 1991-2020. July also saw widespread dry conditions across much of western and central Europe. Several parts of France, Germany, Austria, Hungary, and the Iberian Peninsula recorded soil moisture levels in July that were the lowest since at least 1979.
France faces the most significant projected GDP decline
Among the nations assessed, France is expected to endure the greatest impact. The bank’s estimates suggest that heat and drought could reduce France’s GDP growth by about 1.4 percentage points in 2026. Under this estimate, the country’s annual output might contract by roughly 0.6%. Italy and Spain are also among the more vulnerable large economies, while Belgium is expected to experience a notable effect. The Netherlands could see a growth decline of approximately 0.8 percentage points, rendering its economic activity nearly stagnant for the year.
This heat-related forecast comes amid a broader context of slower economic growth across Europe. In 2025, EU growth reached 1.5%, but a slowdown is anticipated for 2026. The Commission’s spring outlook projected a 0.9% expansion for the euro area this year. Severe weather conditions are expected to exert measurable pressure through lost working hours, reduced agricultural output, and disruptions to infrastructure. These impacts often ripple across sectors, especially when low river levels hinder transport or high temperatures diminish electricity generation and industrial productivity.
Intense weather conditions threaten food supply and industrial output
Research indicates that extreme heat correlates with increased food prices and decreased corporate performance. The European Central Bank observed that the summer heatwave of 2025 added between 0.4 and 0.7 percentage points to the euro area’s unprocessed food prices after one year. Separate studies at the company level in Italy revealed that extreme heat caused sales reductions of approximately 0.8%. Days exceeding 40°C also led to significant losses in productivity and output, according to that research.
The 2026 analysis emphasizes the immediate economic impacts of this summer’s heat and drought, rather than long-term climate projections. The estimated 1% reduction in EU GDP closely aligns with the 1.1% growth forecast for the year. The largest source of losses is attributed to declining labor productivity, with agriculture, energy, and transportation also incurring additional costs. As western Europe experiences extraordinary heat and soil moisture deficits, these figures demonstrate how severe weather has become a tangible factor in Europe’s economic performance for 2026.
