Europe’s Heatwave Deaths Are a Policy Failure, Not a Disaster

Nearly one-in-three Europeans lives in rented housing, yet these tenants are disproportionately confined to energy-inefficient buildings. While homeowners can often adapt their properties, renters frequently lack the legal authority to install necessary cooling protections like external shutters or blinds. Research indicates that 75 percent of the EU’s building stock is currently inefficient, leaving millions trapped in homes that trap heat rather than shield occupants from it.

The crisis is particularly visible in countries like Spain and France. In Spain, where temperatures have climbed 1.69°C since the mid-20th century, roughly 75 percent of buildings fail to meet modern energy standards. Despite multi-billion euro renovation programs, the funding rarely reaches the low-income households that need it most. In France, 66 percent of citizens report difficulty managing indoor heat, with 43 percent of homes lacking basic sun protection on windows.

Grassroots movements are beginning to challenge this status quo. In France, the 'Pas de volets, pas de loyer' campaign demands that tenants be allowed to withhold rent into escrow to fund safety improvements when landlords refuse to act. As the EU approaches the 2026 deadline for National Building Renovation Plans, current proposals remain insufficient. Experts argue that protecting citizens requires a shift toward passive cooling, immediate access to renewable energy systems, and legal protections that prioritize human health over property-owner convenience.
