2025 Heatwaves Cost France 0.3% of GDP, Major Economic Implications Ahead

The recent heatwaves that have swept across France have had a notable economic impact, with a loss estimated at 0.3% of the country's GDP, according to a report by Allianz. The heat has disrupted productivity in several sectors, particularly agriculture, construction, and transport, with severe declines in efficiency noted as temperatures soared above critical thresholds.

Specifically, productivity plummets by 40% at temperatures exceeding 32 degrees Celsius and nearly 70% once temperatures surpass 38 degrees. This trend has raised significant concerns about operational capabilities within affected industries. Furthermore, the labor market has shown signs of strain, particularly impacting seasonal workers, alongside escalating energy costs that businesses must contend with due to the heat.

The report draws a compelling comparison, illustrating that a day of extreme heat can lead to productivity losses equivalent to a half-day of a national strike. Although it is projected that between 30-50% of these economic losses could be recouped, the total cost attributed to the extreme heat is expected to surpass 3 billion euros in 2025. This assessment considers the number of hot days and the inherent vulnerabilities of the French economy.

Looking ahead, analysts warn that the impacts of heatwaves could double by 2030, indicating an urgent need for strategic investments in adaptation measures, such as infrastructure improvements and urban greening initiatives, to mitigate the future economic impacts of rising temperatures. As France grapples with these challenges, the pressing nature of climate adaptation becomes increasingly clear, positioning the heatwaves not just as a seasonal concern but as a pivotal factor influencing the nation’s economic trajectory going forward.
