NETHERLANDS / RankWire.AI / – In Europe, particularly during the summer of 2026, extreme heat and drought conditions are projected to shave approximately 1% off the continent’s economic output, according to an analysis conducted by Triodos Bank. This estimated decline amounts to around €180 billion and occurs amid a year already marked by sluggish growth. The European Commission predicted in May that the EU’s gross domestic product would increase by 1.1% in 2026. This baseline indicates that the expected economic impact from this summer’s severe weather could significantly narrow the growth margin.
The primary contributor to the forecasted economic setback is decreased worker productivity during periods of extreme heat. The report estimates that this effect accounts for roughly 0.6% of EU GDP. The agricultural sector is also under considerable stress following extended periods of high temperatures and dryness across key farming regions. According to the assessment, agricultural output could decline between 3% and 7%. Additionally, disruptions in energy production, transport systems, and logistics further compound the overall economic costs, as elevated temperatures and reduced water levels interfere with normal operations.
Western Europe experienced unprecedented temperatures this summer. According to Copernicus, June and July combined were the region’s hottest such period on record, with an average temperature of 21.62°C, which is 2.79°C above the 1991-2020 average. July also saw widespread dry conditions across much of western and central Europe. Soil moisture levels in parts of France, Germany, Austria, Hungary, and the Iberian Peninsula fell to their lowest July readings since at least 1979.
France faces the greatest estimated GDP decline
Among European nations, France is projected to bear the largest economic impact, with heat and drought potentially reducing its GDP growth by approximately 1.4 percentage points in 2026. This translates to an estimated annual contraction of around 0.6%. Italy and Spain are also among the more vulnerable large economies, while Belgium is expected to see a notable effect. The Netherlands may experience a growth reduction of roughly 0.8 percentage points, bringing its economic activity close to stagnation for the year.
This projection of heat-related economic slowdown coincides with Europe’s existing modest growth trajectory. The EU’s growth rate reached 1.5% in 2025, but it is now facing a slowdown projected for 2026. The European Commission forecast in its spring outlook predicted a 0.9% increase for the euro area this year. Severe weather events exert additional pressure by reducing working hours, diminishing agricultural yields, and causing disruptions to infrastructure. These effects ripple through various sectors, especially when low river levels hinder transportation or high temperatures diminish electricity generation and industrial productivity.
Extreme weather intensifies challenges for food and manufacturing
Research indicates that intense heat is linked to rising food prices and declining corporate performance. The European Central Bank noted that the 2025 summer heatwave contributed between 0.4 and 0.7 percentage points to euro area unprocessed food prices after one year. Independent studies at the firm level in Italy found that extreme heat reduced company sales by approximately 0.8%. Days exceeding 40°C also caused substantial losses in productivity and production, 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. Its estimated 1% reduction in EU GDP closely aligns with the 1.1% growth forecast for the year. The largest source of losses stems from decreased labor productivity, while agriculture, energy, and transportation sectors also incur additional costs. As Western Europe faces record-breaking heat and widespread soil moisture deficits, these figures demonstrate how extreme weather has become a tangible factor influencing Europe’s economic outlook for 2026.
