France's record heatwave forces a U-turn on air conditioning policies

Record temperatures have gripped France, with more than half of the country under the highest heat alert. The hottest day since 1947 was recorded on Tuesday, June 23rd, as a severe heatwave pushed temperatures near or above 40°C in some areas. Schools were forced to close as the extreme conditions took hold. In 2025, the heatwave exposed the strain on public services, prompting a rethink among political leaders. Last year, Green politicians had opposed widespread cooling system installations, calling them environmentally misguided. But the current crisis has shifted their position.

Marine Tondelier, national secretary of the Green Party, now acknowledges the need for air conditioning in schools and hospitals. She insists it should remain an emergency measure rather than a permanent solution. Many in her party have followed suit, endorsing cooling systems for essential public spaces. The change in stance has raised questions about why similar arguments were dismissed last year. Political leaders now recognise air conditioning as a necessary response to extreme heat. The debate continues over how to balance immediate needs with long-term environmental concerns.
