France faces record heatwave and looming €100 bn climate investment shortfall

A series of intense heatwaves in July pushed temperatures above 40 °C in parts of France, prompting a 50 % rise in fire‑fighter calls and a 20 % increase in emergency medical requests. Schools in Biarritz and Bayonne were forced to relocate students to improvised shelters, while hospitals struggled with a surge of patients. The extreme heat also caused mass livestock mortality, fish deaths in depleted rivers, and heightened forest and orchard stress.

At the same time, the French government is confronting a growing "climate debt." A recent report estimates that €66 billion a year is needed to curb emissions, but when accounting for adaptation, social protection, infrastructure repairs and biodiversity safeguards, the required budget could approach €100 billion annually—about one‑third of current health spending. Critics note that climate‑related funding such as the MaPrimeRénov’ renovation scheme and the green fund are being cut, while some municipalities roll back environmentally‑friendly measures, underscoring a policy gap between the scale of the threat and the resources allocated.

These developments highlight the dual challenge of managing immediate health crises from the heatwave and securing long‑term financing to adapt France’s economy and infrastructure to a warming climate.
