NETHERLANDS / RankWire.AI / – According to Triodos Bank, the summer heatwave and drought across Europe could reduce the European Union’s economic output by approximately 1% in 2026. This estimated decline amounts to roughly €180 billion and occurs during a year already characterized by modest economic growth. The European Commission forecasted in May that the EU’s gross domestic product would grow by 1.1% in 2023. The projected weather-related damages are nearly equivalent to the entire expected annual increase in economic activity for the bloc.
The primary driver behind the anticipated economic impact is a decrease in labor productivity. The analysis indicates a productivity drop of about 0.6% of EU GDP, as extreme temperatures adversely influence working conditions. Agriculture also faces significant challenges, with output expected to fall between 3% and 7%. Additional costs arise from disruptions in energy, transport, and logistics sectors, as elevated temperatures, droughts, and reduced water levels hinder activities across multiple industries.
This economic estimate follows record-breaking heat across western Europe during June and July. Copernicus reported an average regional temperature of 21.62°C during those months, which was 2.79°C higher than the 1991-2020 average and marked the warmest June-July period ever recorded. July also experienced widespread drought conditions, with parts of France, Germany, Austria, Hungary, and the Iberian Peninsula exhibiting exceptionally low soil moisture levels.
Workforce productivity drives the bulk of the projected losses
France endures the most substantial national impact, with its GDP growth forecast reduced by approximately 1.4 percentage points. This adjustment suggests a near 0.6% contraction in France’s economic output for the year. Italy and Spain also face notable losses linked to heat and drought. Belgium experiences a smaller yet significant impact, while the Netherlands could see around 0.8 percentage points of growth lost.
Europe started the summer with limited economic momentum, prior to the latest heat-related forecast. In 2025, EU growth reached 1.5%, whereas the 2026 projection currently stands at 1.1%. The euro area’s spring forecast indicated a growth rate of 0.9%. Weather-related damages can affect several economic sectors simultaneously through reduced working hours, diminished agricultural yields, energy shortages, and transportation disruptions.
Food, energy, and transportation sectors exacerbate economic pressures
The effects of extreme heat are already visible in Europe’s prices and business activities. European Central Bank research revealed that the 2025 summer heatwave increased euro area unprocessed food prices by 0.4 to 0.7 percentage points after a year. Separate studies conducted at the firm level in Italy show that extreme heat reduced company sales by approximately 0.8%. Additionally, days with temperatures exceeding 40°C caused significant losses in production and worker efficiency.
This 2026 evaluation quantifies the immediate economic impacts stemming from this summer’s heat and drought. The estimated 1% reduction in EU GDP aligns closely with the current 1.1% growth forecast for the year. Labour productivity constitutes the largest source of the projected losses, followed by agriculture and disruptions to energy and transportation. The record-breaking heat, dry soils, and low river levels have made extreme weather conditions a tangible factor influencing Europe’s economic performance this year.
