2026 Heatwave Threatens French Economy with Billion-Euro Losses and Calls for Worker Protections

France is currently enduring an unprecedented heatwave, with temperatures surpassing 44°C across 54 departments, intensifying threats to both public health and the economy. The extreme weather has led to widespread crises, including the closure of 1,352 schools and urgent calls to safeguard workers exposed to hazardous conditions.

A comprehensive study by Allianz Trade reveals severe economic consequences, projecting that repeated heatwaves could shrink France's GDP by up to €210 billion by 2030. The study highlights a sharp decline in productivity once temperatures exceed 30°C, with hourly production dropping by approximately €1.10 per degree increase up to 35°C, and even more beyond that threshold. The French economy's heavy reliance on services and agriculture makes it particularly vulnerable to these climate disruptions, threatening lower tax revenues and increased public expenditure on healthcare, emergency responses, and infrastructure adaptation.

In response to these mounting pressures, former Economy Minister Bruno Le Maire outlined three main priorities to revitalize France's economy in this challenging context. Emphasizing a break from reliance on gas and oil and addressing systemic issues exposed by recent judicial controversies, France aims to modernize its economy effectively. Concurrently, a notable initiative is the proposal of a 'climate leave,' championed by Sabrina Sebaihi of the Ecologist and Social party, aiming to protect workers whose health is at risk due to extreme temperatures.

These developments come as Europe faces a potential 5 to 7% decrease in economic growth by 2030 due to rising heatwaves, further underscoring the urgency of adaptive measures. The government is now tasked with balancing economic recovery ambitions alongside immediate public health and workforce protection amid this escalating climate crisis.
