EU Heatwaves Cost 180 Billion Euros
A new analysis by a Dutch bank reveals that this year's heat shock could wipe out nearly all of the European Union's projected growth, with France potentially slipping into recession.
A new analysis by a Dutch bank reveals that this year's heat shock could wipe out nearly all of the European Union's projected growth, with France potentially slipping into recession.
This year's prolonged heatwaves across Europe will leave a deep mark not only on public health and forests but also on the economic balance sheets of member states. According to extensive research by the Dutch Triodos Bank, reported by Euronews, the total economic damage from extreme temperatures and wildfires in 2026 will reach as much as 180 billion euros.
That figure corresponds to roughly one percent of the European Union's gross domestic product. It practically cancels out the modest growth of 1.1 percent that Brussels had forecast for this year, leaving the bloc on the brink of economic stagnation.
Bank analysts have identified four main channels through which losses spill into the economy. Farmers are hit first, with drastically reduced crop yields and milk production, along with higher food prices, accounting for about 0.15 percent of GDP.
The energy sector suffers a similar blow. Reduced output from hydroelectric, nuclear, and thermal power plants, coupled with lower efficiency of solar panels at high temperatures, has driven up wholesale electricity prices. According to a report by Financije.hr, this sector loses between 0.12 and 0.15 percent of GDP. Transport infrastructure, disrupted by rail, road, and river transport issues, accounts for an additional 0.15 percent.
But the biggest hit, though the hardest to measure precisely, comes from declining labor productivity. Researchers note that output per worker begins to drop as soon as temperatures exceed the 25 to 30 degrees Celsius threshold. The decline is most dramatic for physical outdoor work, but office workers are not spared either, as hot nights disrupt sleep and cognitive function. An analysis by insurer Allianz, cited in the study, shows that each degree above 30, if sustained for several consecutive days, reduces output per hour worked by about three percent.
The study's findings are not just a list of the hottest countries but a complex matrix that considers economic structure, the share of air-conditioned spaces, travel habits, and population adaptability. In this calculation, France is the hardest hit. Due to the high exposure of its key sectors, it loses 1.4 percentage points of growth, which, for a country with already fragile foundations, means a GDP decline of 0.6 percent and a slide into negative territory.
The Netherlands records a loss of about 0.8 percentage points, bringing it to complete stagnation. On the other hand, Spain and Italy, despite having the most exposed workforce and the highest number of tropical days, suffer a smaller one-off shock thanks to decades of adaptation in work rhythms and infrastructure. Poland, which would be highly vulnerable due to low air-conditioning rates, is saved by somewhat lower summer temperatures, maintaining solid growth of around 2.9 percent.
Official statistics do not capture the heaviest part of this year's balance sheet. During the June heatwave alone, more than 20,000 heat-related deaths were recorded in France, Germany, Spain, and Italy. When the total estimated mortality of around 25,000 people is converted into years of life lost, the economic cost reaches between 1.5 and 7 billion euros.
Wildfires, which by early August had consumed more than 490,000 hectares across the Union-more than double the twenty-year average-bring additional damage. The loss of ecosystems in burned areas is estimated at between 100 million and 4.6 billion euros.
The study's authors emphasize that their estimates are based on very conservative assumptions and that adaptation measures can mitigate productivity losses by at most 40 percent. Therefore, they conclude that adaptation alone is insufficient and sharply criticize the European Commission's recent moves to ease the dynamics of the carbon emissions trading system, calling them a step in entirely the wrong direction.
