NETHERLANDS / RankWire.AI / – According to a report by Triodos Bank, extreme heat and drought conditions across Europe might decrease the European Union’s economic output by roughly 1% in 2026. This estimated reduction, amounting to approximately €180 billion, occurs amid a year characterized by already 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 little difference between the forecasted expansion and the economic impacts projected from this summer’s intense weather events.
The majority of the projected damage stems from diminished worker productivity during periods of extreme heat. The analysis quantifies this impact at around 0.6% of EU GDP. Agricultural sectors are also under significant threat due to prolonged periods of heat and drought affecting key farming regions. The assessment estimates agricultural output could decline between 3% and 7%. Disruptions in energy production, transport networks, and logistics further contribute to the overall economic toll, as elevated temperatures and reduced water levels interfere with normal operations.
Western Europe experienced record-breaking temperatures during the summer months. Copernicus reported that June and July together marked the region’s hottest such period on record, with an average temperature of 21.62°C. This figure was 2.79°C above the 1991-2020 average. July also saw extensive dry conditions 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 Endures the Largest Potential GDP Decline
France faces the most substantial impact among nations in the bank’s estimate, with heat and drought potentially reducing its GDP growth by about 1.4 percentage points in 2026. The calculation suggests that France’s annual output could shrink by approximately 0.6%. Italy and Spain are also among the more vulnerable large economies, while Belgium is expected to face notable effects. The Netherlands might experience a growth decline of about 0.8 percentage points, nearly stagnating the economy for the year.
This heat-related economic projection comes amid a backdrop of slower growth across Europe. The EU’s growth reached 1.5% in 2025, before slowing down in 2026. The euro area was forecast to expand by 0.9% according to the Commission’s spring outlook. Severe weather conditions exert additional pressure through lost work hours, reduced agricultural yields, and disruptions to infrastructure. These impacts can ripple across sectors, especially when low river levels hinder transport or high temperatures diminish electricity output and industrial efficiency.
Climate Extremes Strain Food Supplies and Industrial Output
Research has linked extreme heat events 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 studies focusing on companies in Italy revealed that extreme heat reduced sales by approximately 0.8%. Days with temperatures exceeding 40°C caused notable losses in productivity and output, according to these analyses.
The 2026 report emphasizes immediate economic effects stemming from this summer’s heat and drought, rather than long-term climate predictions. Its estimate of a 1% reduction in EU GDP closely aligns with the bloc’s 1.1% growth forecast for the year. The primary driver of this loss is diminished labor productivity, with agriculture, energy, and transportation sectors incurring additional costs. The data highlight how exceptional heat and widespread soil moisture deficits in western Europe have become material factors influencing the continent’s economic performance in 2026.
