Extreme Heat Creates an €800 Billion Hole
France, Germany, and Italy are hardest hit, while agriculture and construction see productivity drops at temperatures above 30°C.

Extreme heat is becoming an increasingly significant threat to the European economy, with estimated damages of €800 billion. Recent analyses warn that more frequent heatwaves pose not only a public health risk but also a serious economic one, with major economies like France, Germany, and Italy particularly exposed.
According to a simulation by Allianz SE, Europe's largest primary insurer, France could lose around $240 billion (€211 billion) in economic output by 2030. The analysis, based on heatwave data from 2014 to 2024, covered more than 40 countries worldwide.
Italy and Germany follow with estimated losses of $147 billion and $131 billion, respectively. Spain rounds out the list with a potential loss of around $120 billion. EUobserver notes that the fiscal consequences will hit France, Italy, and Spain hardest, as these are economies that "can least absorb them."
Research shows that at temperatures above 30°C, human productivity significantly declines. "Extreme heat and heatwaves are structural risks that pose threats across multiple sectors and the broader economy," Arianna Giannetti, a climate expert at the European Environment Agency (EEA), told EUobserver.
Agriculture and construction are among the hardest-hit sectors. "Compared to storms or floods, extreme heat less often manifests as direct damage," the Allianz report states. However, the consequences are long-term and devastating.
Italian agro-climatologist Marco Moriondo specifically warned about the vulnerability of crops. "A single day of extreme heat during flowering can wipe out an entire harvest, even if the rest of the season is perfect," he told EUobserver, speaking about olive crops.
Studies predict that olive oil yields on the Iberian Peninsula could drop by up to 28 percent. Spain, which produces more than 50 percent of the world's olive supply, is particularly sensitive to this trend.
As devastating wildfires rage in France and Spain, having consumed more than 42,000 hectares in France and 80,000 hectares in Spain, over 300,000 people have been evacuated. Temperatures have exceeded 40°C in several countries, and overstretched health systems are recording thousands of excess deaths across Europe.
"Heat stress is often called the silent killer," wrote Tedros Adhanom Ghebreyesus, head of the World Health Organization (WHO), on platform X.
Hans Martin Füssel, a climate adaptation expert at the EEA, emphasizes the broader implications. "Extreme heat is a major risk to health and the economy in Europe, and it has significant macroeconomic, even fiscal, implications," he told EUobserver.
While analyses show that the largest economies are the most exposed, the EEA is cautious about ranking. "As the EEA, we would not officially endorse that Germany or France is the 'most' affected country," Füssel clarified, stressing that cross-country comparisons depend on the methodology used.
Losses from climate hazards in Europe are spiking sharply, reaching around €50 billion in 2021-2022. A growing body of evidence indicates that heat is no longer just a public health challenge but also a significant economic problem requiring urgent adaptation.
