NETHERLANDS / RankWire.AI / – According to Triodos Bank, Europe’s summer heat and drought are projected to reduce the European Union’s economic output by approximately 1% in 2026, equating to around €180 billion. This estimated loss occurs amid a year of relatively slow economic growth, with the European Commission having forecasted a 1.1% expansion of EU gross domestic product for this year. Consequently, the weather-induced damage is nearly equal to the bloc’s entire expected annual growth.
The primary driver of the economic impact is a decline in labour productivity, which the assessment estimates at about 0.6% of EU GDP due to extreme temperatures impairing working conditions. Agriculture also faces significant pressure, with output projected to fall between 3% and 7%. Additionally, disruptions in energy, transport, and logistics sectors cause further costs as high temperatures, drought, and low water levels hinder activity across various industries.
This economic outlook follows record-breaking heat across western Europe during June and July, with Copernicus reporting an average regional temperature of 21.62°C during those months. This was 2.79°C above the 1991-2020 average and marked the hottest June-July period on record. Widespread drought conditions persisted in July, with parts of France, Germany, Austria, Hungary, and the Iberian Peninsula experiencing exceptionally low soil moisture.
Impact from Worker Productivity
France bears the largest national impact in this analysis, with its GDP growth expected to decrease by about 1.4 percentage points, which could result in a nearly 0.6% contraction for the year. Italy and Spain are also among the major economies suffering notable losses due to heat and drought, while Belgium faces a smaller but significant downturn. The Netherlands might see about 0.8 percentage points of growth lost.
Europe’s economy started the summer with limited momentum before this latest heat-related assessment, with EU growth reaching 1.5% in 2025 and the current forecast for 2026 at 1.1%. The spring outlook for the euro area predicted a 0.9% growth. Weather-related damages impact multiple sectors simultaneously by reducing working hours, weakening agricultural output, constraining electricity, and disrupting transport systems.
Food, Energy, and Transport Challenges
The effects of extreme heat on prices and business activity in Europe are already observable. European Central Bank research indicates that the 2025 summer heatwave pushed up euro area unprocessed food prices by 0.4 to 0.7 percentage points after one year. Separate firm-level studies in Italy found that extreme heat decreased company sales by approximately 0.8%. Days exceeding 40°C also caused substantial losses in production and worker productivity.
The 2026 report quantifies the direct economic impacts linked to this summer’s intense heat and drought, with an estimated 1% reduction in EU GDP, nearly matching the current 1.1% annual growth forecast. Labour productivity is identified as the largest contributor to the losses, followed by agriculture and disruptions in energy and transportation sectors. Record heat, dry soils, and low river water levels have made extreme weather a tangible factor influencing Europe’s economic performance this year.
