NETHERLANDS / RankWire.AI / – According to new findings from Triodos Bank, Europe’s record-breaking summer heat and drought conditions could lead to a roughly 1% decline in EU economic output by 2026. The predicted loss amounts to approximately €180 billion and is nearly equal to the European Commission’s current projection for the bloc’s growth. In May, the Commission forecasted that EU gross domestic product would increase by 1.1% this year. This comparison highlights the magnitude of weather-related damage as estimated by the bank’s research.

Triodos Bank examined four primary channels: labour productivity, agriculture, energy generation, and transport and logistics. It concluded that diminished labour productivity could decrease EU GDP by around 0.6%, making it the largest individual factor. Additionally, the bank projects EU agricultural production to fall between 3% and 7% due to the ongoing heat and drought. Reduced energy output, rising electricity costs, and disruptions in transportation further contribute to the overall economic impact across Europe.
This economic analysis follows an extraordinary period of heat experienced in western Europe. According to Copernicus, the region recorded its warmest June-July period on record, with an average temperature of 21.62°C. This marked an increase of 2.79°C compared to the 1991-2020 average for those months. July also brought widespread drought conditions across western and central Europe, characterized by unusually low river flows and soil moisture levels. Several areas, including parts of France, Germany, Austria, Hungary, and the Iberian Peninsula, experienced their lowest July soil moisture readings since at least 1979.
Losses Driven by Productivity and Agricultural Declines
France faces the most significant estimated national impact in the Triodos analysis, with a calculated reduction of 1.4 percentage points in its GDP growth, resulting in an estimated full-year contraction of about minus 0.6%. Italy and Spain are also expected to encounter considerable losses, whereas Belgium’s impact appears smaller. In the Netherlands, the bank projects a 0.8 percentage-point decrease in growth, which results in relatively stable economic activity. Poland seems less vulnerable to these effects due to the assumption of fewer extremely hot days in that country.
Ahead of the heatwave, Europe was already experiencing a sluggish growth outlook. The European Commission anticipates EU GDP growth to slow from 1.5% in 2025 to 1.1% in 2026. It also predicts EU inflation will rise to 3.1%, with energy costs remaining a significant pressure. Meanwhile, 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 impacts.
Infrastructure Under Strain from Heat and Drought
Copernicus reported that June 2026 was the warmest June recorded in western Europe and the second-warmest globally. Heatwaves persisted into July, notably affecting France, Spain, England, and Ireland. The dry weather reduced river flows across large swathes of Europe, increasing pressure on agriculture, transportation, and energy sectors. Additionally, Copernicus highlighted exceptional wildfire activity in western Europe, with fires in France’s Gironde region burning nearly 42,000 hectares, marking the largest area recorded for France in the European fire monitoring database.
The Triodos estimate emphasizes the immediate effects of this summer’s extreme weather in 2026 rather than projecting a long-term climate scenario. The European Central Bank has separately documented how extreme weather events can decrease economic output and elevate food prices. Its research indicated that the 2025 summer heatwave contributed up to 0.7 percentage points to euro area unprocessed food prices after a year. The estimated 1% GDP loss from Triodos Bank now aligns closely with the European Commission’s most recent forecast of 1.1% EU growth for 2026.
