Heatwave Drives Political Rift Over Air‑Conditioning in France

As France grapples with a record 40°C day, lawmakers clash over subsidising air‑conditioning, revealing deep ideological divides amid rising climate urgency.

France’s record‑temperature heatwave, clocking in near 40°C, has thrust the debate over air‑conditioning into the national spotlight. Only a quarter of French homes are equipped with cooling units, which has prompted calls for government‑backed subsidies and a rush for portable devices. The issue cuts across the political spectrum: the Green left, traditionally opposed, now voices support, while the populist Marine Le‑Pen pushes a nationwide rollout backed by a €20 bn loan programme. Environmentalists warn that air‑conditioners drive electricity use and fugitive refrigerant leaks, but the health and operational risks to schools and hospitals have forced a reassessment of policy. A heat‑map of France shows most regions under high‑heat warnings, offering a stark visual of the stakes involved.

With temperatures soaring, France is being forced to re‑think its longstanding reservations about one possible answer to climate change: air‑cond.

This week’s debate over la clim (climatisation) has erupted again, with Marine Le Pen on the far right urging a mass subsidised roll‑out and the traditionally hostile Greens conceding that some air‑conditioning may now be inevitable.

Only 25% of French households are equipped with an air‑cond unit, compared with 50% in Spain and Italy, and 90% in the US and Japan. French schools and hospitals are also rarely fitted; thousands have had to shut this week, and medical staff complain of intolerable conditions.

The hottest day on record – 40°C – triggered a rush to buy portable appliances, so children could spend hours in class and residents could survive the night.

Long‑standing opponents of air‑conditioners, mainly on the environmental left, are now admitting it will be part of France’s response to global warming.

Marie Tondelier, head of the Ecologists party, broke taboo by saying schools and hospitals will need them. She quoted the slogan "anti‑clim dogma" and warned that "there are places where we just can’t do without it now."

The Green movement has dubbed air‑conditioning the worst solution for climate change, but the deadly heat has forced a reassessment.

Giant new hospitals, such as the one in Nantes, will have AC in only half the rooms, provoking ire from medical trade unions. “In the environmental context, we should have la clim everywhere,” said CGT union officer Olivier Terrien.

Paris regional council president Valérie Pécresse – a conservative – said the state suffers from an anti‑clim ideology, but “air‑conditioning has to be included alongside other cooling methods.” She aims to equip all Parisian buses and trains by 2032 and criticises her Socialist predecessor for not seeing its importance.

The right has always been more pro‑clim than the left – and none more so than the National Rally (RN) of Marine Le Pen. This week she has been calling for a nationwide “plan clim” to equip all schools and hospitals.

RN spokesman Jean‑Philippe Tanguy outlines €20bn interest‑free loans to install units in 30‑40 million households. Critics call the plan opportunistic and uncoupled from a coherent climate strategy.

With temperatures approaching danger levels across France and schools and hospitals at risk of breakdown, the consensus is clear: more clim is inevitable.
