NETHERLANDS / RankWire.AI / – According to a new analysis from Triodos Bank, Europe’s intense summer heat and drought could lead to a reduction of about 1% in EU economic output by 2026. This estimated loss is roughly €180 billion and closely matches the European Commission’s current growth forecast for the bloc. In May, the Commission predicted EU gross domestic product would increase by 1.1% this year. The comparison highlights the weather-related damage projected in the bank’s analysis.

Triodos Bank examined four main areas: labour productivity, agriculture, energy production, and transport and logistics. It found that lower labour productivity alone could reduce EU GDP by about 0.6%, making it the largest factor. The bank also predicts EU agricultural output could decline between 3% and 7% due to heat and drought conditions. Disruptions in power generation, rising electricity prices, and transport issues are also expected to contribute to economic losses across Europe.
This economic assessment comes amid an extraordinary period of heat across western Europe. Copernicus reported that the region experienced its hottest June-July period on record, with an average temperature of 21.62°C. This was 2.79°C above the average for those months during 1991-2020. July also saw widespread dryness across western and central Europe, with unusually low river flows and soil moisture. Several parts of France, Germany, Austria, Hungary, and the Iberian Peninsula recorded their lowest July soil moisture levels since at least 1979.
Losses Driven by Productivity and Agriculture
France is expected to face the largest impact in the Triodos analysis. The bank estimated a 1.4 percentage-point decrease in French GDP growth, bringing the full-year outlook to about minus 0.6%. Italy and Spain are also projected to encounter significant losses, while Belgium’s impact is smaller. In the Netherlands, the bank estimates a 0.8 percentage-point reduction in growth, leaving overall economic activity relatively unchanged. Poland shows less vulnerability, as the analysis assumes fewer exceptionally hot days there.
Europe’s growth prospects for summer were already weak before considering the heat-related effects. The European Commission forecasts EU GDP growth to slow from 1.5% in 2025 to 1.1% in 2026. Inflation in the EU is also expected to rise to 3.1%, with energy prices remaining a key challenge. Meanwhile, the European Central Bank predicts euro area growth of 0.8% for this year and an inflation rate of 3.0%. These forecasts predate the latest summer heat and drought damage estimates.
Infrastructure Under Pressure from Heat and Drought
Copernicus reported that June 2026 was western Europe’s hottest June on record and the second-warmest globally. Heatwaves continued into July, especially across France, Spain, England, and Ireland. Dry conditions caused river flows to drop across large parts of Europe, straining agriculture, transport, and energy systems. Copernicus also noted exceptional wildfire activity in western Europe. Fires in France’s Gironde region burned nearly 42,000 hectares, the largest area recorded for France in the European fire monitoring database.
The Triodos estimate emphasizes the impacts of this summer’s extreme weather in 2026 rather than a long-term climate scenario. The European Central Bank has separately documented how extreme weather can decrease economic output and increase food prices. Its research showed that the 2025 summer heatwave added up to 0.7 percentage points to 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.
