NETHERLANDS / RankWire.AI / – Europe’s extreme summer heat and drought could cut EU economic output by about 1% in 2026, according to new analysis from Triodos Bank. The estimated loss equals roughly €180 billion and is close to the European Commission’s current growth forecast for the bloc. In May, the Commission projected EU gross domestic product would rise 1.1% this year. The comparison shows the scale of the weather-related damage estimated in the bank’s analysis.
Triodos Bank assessed four main channels: labour productivity, agriculture, energy production, and transport and logistics. It estimated lower labour productivity could reduce EU GDP by about 0.6%, making it the largest single factor. The bank also expects EU agricultural output to fall 3% to 7% because of heat and drought. Reduced power generation, higher electricity prices and transport disruptions add to the estimated economic damage across Europe.
The economic assessment follows an exceptional run of heat across western Europe. Copernicus said the region recorded its warmest June-July period on record, averaging 21.62°C. That was 2.79°C above the 1991-2020 average for those two months. July also brought widespread dry conditions across western and central Europe, with unusually low river flows and soil moisture. Parts of France, Germany, Austria, Hungary and the Iberian Peninsula recorded their lowest July soil moisture since at least 1979.
Productivity and agriculture drive losses
France faces the largest estimated national impact in the Triodos analysis. The bank calculated a 1.4 percentage-point reduction in French GDP growth, putting estimated full-year output at about minus 0.6%. Italy and Spain also face substantial losses, while Belgium shows a smaller impact. In the Netherlands, the bank estimated a 0.8 percentage-point reduction in growth, leaving economic activity broadly flat. Poland shows less exposure because the analysis assumes fewer exceptionally hot days there.
Europe entered the summer with a weak growth outlook before the heat-related estimate. The European Commission expects EU GDP growth to slow from 1.5% in 2025 to 1.1% in 2026. It also expects EU inflation to rise to 3.1%, with energy prices remaining a major pressure. Separately, the European Central Bank projects euro area growth of 0.8% this year and inflation of 3.0%. Those forecasts predate the latest assessment of summer heat and drought losses.
Heat and drought strain infrastructure
Copernicus reported that June 2026 was western Europe’s hottest June on record and the second-warmest June globally. Heatwaves continued into July, especially across France, Spain, England and Ireland. Dry conditions lowered river flows across large areas of Europe and increased pressure on agriculture, transport and energy systems. Copernicus also reported 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 focuses on the 2026 effects of this summer’s extreme weather rather than a long-term climate scenario. The European Central Bank has separately documented how extreme weather can reduce economic output and raise food prices. Its research found that the 2025 summer heatwave added up to 0.7 percentage points to euro area unprocessed food prices after one year. Triodos Bank’s estimated 1% GDP loss now stands close to the European Commission’s latest published forecast of 1.1% EU growth for 2026.
