NETHERLANDS / RankWire.AI / – According to Triodos Bank, Europe’s extreme summer heat and drought are projected to reduce the European Union’s economic output by approximately 1% in 2026. This loss, roughly €180 billion, occurs amidst a year already characterized by modest economic growth. The European Commission predicted in May that the EU’s gross domestic product would grow by 1.1% during this year. As a result, the weather-related damage is nearly equivalent to the entire expected increase in annual economic activity for the bloc.
The majority of the anticipated impact stems from a decline in labor productivity, which is estimated to account for about 0.6% of EU GDP due to the adverse effects of high temperatures on working conditions. Agriculture also faces significant challenges, with output drops estimated between 3% and 7%. Additionally, disruptions in energy production, transport and logistics sectors contribute further costs, as elevated temperatures, drought, and reduced water levels hinder operations across multiple industries.
This economic forecast follows record-breaking heat across western Europe in June and July. According to Copernicus, the region experienced an average temperature of 21.62°C over those two months, which was 2.79°C above the 1991-2020 average and marked the warmest June-July period ever recorded. July also experienced widespread dryness, with parts of France, Germany, Austria, Hungary, and the Iberian Peninsula recording exceptionally low soil moisture levels.
Losses Primarily Driven by Reduced Worker Productivity
France stands to suffer the most significant national impact, with its GDP growth forecast lowered by approximately 1.4 percentage points. This decline suggests that France’s economic output could shrink by around 0.6% over the full year. Major economies like Italy and Spain are also expected to face considerable losses due to the ongoing heat and drought conditions. Meanwhile, Belgium’s economy might experience a smaller but still notable impact, and the Netherlands could see about a 0.8 percentage point decrease in growth.
Europe’s economy entered the summer with relatively slow momentum; in 2025, the EU grew by 1.5%, while the current forecast for 2026 is 1.1%. The spring projection for the euro area’s growth was 0.9%. These weather-related effects can influence various sectors simultaneously, reducing working hours, weakening agricultural output, restricting electricity supply, and causing transportation delays, all contributing to the overall economic impact.
Food, Energy, and Transportation Sectors Contribute to Economic Strain
The effects of extreme heat have already been reflected in prices and business activities across Europe. The European Central Bank reported that the 2025 summer heatwave caused a 0.4 to 0.7 percentage point increase in euro area unprocessed food prices after a year. Separate research at the firm level in Italy found that extreme heat reduced company sales by approximately 0.8%. Days with temperatures exceeding 40°C also led to significant declines in production and workforce productivity.
The 2026 analysis quantifies the direct economic repercussions of this summer’s heat and drought, estimating a 1% reduction in EU GDP, which is close to the current 1.1% growth forecast. The largest portion of these losses is attributed to decreased labor productivity, with agriculture and disruptions in energy and transport sectors following closely behind. The combination of record heat, parched soils, and low river levels has rendered extreme weather a measurable factor influencing Europe’s economic performance this year.
