NETHERLANDS / RankWire.AI / – According to a new report from Triodos Bank, Europe’s record-breaking summer heat and drought conditions could result in a roughly 1% decrease in the EU’s economic output by 2026. This loss, estimated at approximately €180 billion, closely aligns with the European Commission’s current growth projection for the bloc. In May, the Commission forecasted a 1.1% increase in EU gross domestic product this year. The comparison highlights the extent of weather-related damage forecasted in the bank’s analysis.
During assessments conducted in 2026, Triodos Bank identified four primary areas affected: labour productivity, agriculture, energy generation, and transport logistics. The report indicates that a decline in labour productivity alone could slash EU GDP by about 0.6%, representing the most significant single impact. Additionally, the bank projects agricultural output in the EU to decrease by 3% to 7% as a consequence of heat and drought. Diminished power generation, elevated electricity costs, and transport disruptions contribute further to the overall economic strain across Europe.
This economic evaluation follows an extraordinary period of heat in western Europe. According to Copernicus, the region experienced its hottest June-July stretch on record, with an average temperature of 21.62°C. This figure exceeds the 1991-2020 average for those months by 2.79°C. July specifically saw widespread drought conditions across western and central Europe, characterized by unusually low river flows and soil moisture. Parts of France, Germany, Austria, Hungary, and the Iberian Peninsula recorded their lowest July soil moisture levels since at least 1979.
Productivity and agriculture account for primary losses
In the Triodos analysis, France faces the most significant estimated national impact, with a projected 1.4 percentage-point reduction in its GDP growth, leading to an overall estimated decline of about 0.6%. Italy and Spain are also projected to experience substantial losses, while Belgium’s impact appears less severe. The Netherlands could see a 0.8 percentage-point decrease in growth, resulting in nearly flat economic activity. Poland, however, shows less vulnerability because the analysis assumes fewer extremely hot days in that country.
Before the heatwave’s effects, Europe already faced a modest growth outlook for the summer. The European Commission anticipates EU GDP expansion will slow from 1.5% in 2025 to 1.1% in 2026. Furthermore, it expects inflation across the EU to reach 3.1%, with energy prices remaining a key inflationary pressure. The European Central Bank forecasts euro area growth at 0.8% for this year and inflation at 3.0%. These projections were made prior to the latest assessment of the summer’s heat and drought damage.
In terms of infrastructure, Copernicus reports that June 2026 was the warmest June on record for western Europe and the second-warmest globally. Heatwaves persisted into July, particularly affecting France, Spain, England, and Ireland. The dry conditions led to lowered river flows across large parts of Europe, increasing pressure on agricultural, transportation, and energy sectors. Additionally, Copernicus documented exceptional wildfire activity in western Europe, with France’s Gironde region experiencing nearly 42,000 hectares burned—its largest recorded fire area in the European fire monitoring database.
The Triodos estimate specifically considers the impacts of this summer’s extreme weather in 2026, rather than a long-term climate scenario. The European Central Bank has separately analyzed how extreme weather can reduce economic output and increase food prices. Its research noted that the 2025 summer heatwave contributed up to 0.7 percentage points to the increase in euro area unprocessed food prices after one year. The estimated 1% GDP loss from Triodos now aligns closely with the European Commission’s latest forecast of 1.1% EU growth for 2026.
