NETHERLANDS / RankWire.AI / – According to an evaluation by Triodos Bank, extreme temperatures and drought conditions across Europe could lead to a reduction of approximately 1% in the economic output of the European Union in 2026. This decline is estimated to be around €180 billion and occurs amid a year already characterized by sluggish growth. The European Commission projected in May that the EU’s gross domestic product would grow by 1.1% in 2026. This baseline indicates a narrow margin between expected growth and the economic impact of this summer’s extreme weather events.
The primary contributor to the projected economic damage is a decrease in worker productivity during heatwaves. The study estimates this factor accounts for roughly 0.6% of EU GDP. The agricultural sector also faces significant challenges following extended periods of heat and drought across key farming regions. The report suggests crop yields might decline between 3% and 7%. Additionally, disruptions in energy production, transport networks, and logistics further compound the overall economic toll, as high temperatures and reduced water levels hamper normal operations.
This summer has seen record-breaking temperatures in Western Europe. The Copernicus Climate Change Service announced that June and July together marked the warmest such period on record for the region, with an average temperature of 21.62°C. This level surpasses the 1991-2020 average by 2.79°C. Prolonged dry spells affected large parts of western and central Europe during July, with regions including France, Germany, Austria, Hungary, and the Iberian Peninsula experiencing their lowest soil moisture levels since at least 1979.
France faces the greatest potential reduction in GDP
Among EU countries, France is projected to experience the most significant economic impact. The analysis suggests that heat and drought could cut French GDP growth by about 1.4 percentage points in 2026, translating to an approximate 0.6% contraction in annual output. Italy and Spain are also among the most vulnerable large economies, with Belgium expected to see notable effects as well. The Netherlands might experience a growth decline of about 0.8 percentage points, which could result in economic activity remaining nearly stagnant for the year.
This heat-related economic forecast coincides with a period of already decelerating growth in Europe. In 2025, EU growth reached 1.5%, but a slowdown is now anticipated for 2026. The European Commission previously projected a 0.9% expansion for the euro area this year. The impacts of severe weather—such as lost working hours, diminished agricultural yields, and infrastructure disruptions—are expected to impose additional strains on the economy. These effects tend to cascade across different sectors when low river water levels hinder transportation or high temperatures reduce electricity generation and industrial productivity.
Weather Extremes Amplify Food and Industrial Sector Pressures
Research into economic impacts has also linked extreme heat events with rising food prices and reduced 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 within a year. Separate analyses at the firm level in Italy indicated that extreme heat decreased company sales by approximately 0.8%. Days exceeding 40°C in temperature caused notable losses in production and efficiency, according to these studies.
The 2026 assessment emphasizes the immediate economic effects of this summer’s heat and drought rather than long-term climate change projections. Its estimated 1% reduction in EU GDP closely aligns with the forecasted 1.1% growth for the year. The primary source of losses appears to be diminished labor productivity, with agriculture, energy, and transportation sectors also incurring additional costs. As Western Europe endures exceptional heat and widespread soil moisture deficits, these figures underscore how severe weather phenomena have become material factors influencing Europe’s economic outlook in 2026.
