As a blistering heatwave grips Western Europe, France finds itself in the grip of a political row over air conditioning. The divide is not just about comfort; it is about class, environment, and national identity. On one side, the government and business leaders champion modern cooling as a right. On the other, green activists and left-wing politicians decry it as an energy-guzzling symbol of inequality. Amid the fray, a British innovation in passive cooling is being touted as a potential solution.
The heatwave, which saw temperatures soar past 40C in Paris, has turned the debate toxic. President Macron’s government has called for the expansion of air conditioning in public buildings, including schools and hospitals, arguing that it is a matter of public health. “We cannot let our citizens suffocate,” said a spokesperson for the Ministry of Ecological Transition. Yet critics point to the irony of a nation that signed the Paris climate accord pushing for more AC units, which emit potent greenhouse gases.
The political divide cuts deep. In working-class suburbs, where many live in poorly insulated flats with no green space, the demand for air conditioning is highest. But these communities are also those least able to afford the running costs. Meanwhile, in affluent neighbourhoods, air conditioners hum away, often installed by those who also drive SUVs and fly on holiday. This has created a “cooling apartheid,” said one Parisian activist. “The rich have their private microclimates, while the poor sweat it out.”
Into this charged atmosphere comes a British innovation: a passive cooling system that requires no electricity. Developed by a team at the University of Cambridge, the system uses a combination of reflective materials and phase-change materials that absorb heat during the day and release it at night. The technology has been trialled successfully in social housing in London, where it kept indoor temperatures 5C cooler without a single watt of power. “This is not a silver bullet,” said lead researcher Dr. Emily Watson. “But it shows that we can adapt our buildings without resorting to high-energy consumerism.”
The French government has expressed cautious interest. A spokesperson for the Ministry of Housing said they were “monitoring the technology,” but warned that retrofitting France’s ageing housing stock would be costly. The trade unions, however, are more enthusiastic. The CGT, one of France’s largest unions, has called for government subsidies for passive cooling, arguing that it would create jobs and reduce energy bills for workers.
The political battle lines are now drawn. The far-right Rassemblement National has seized on the issue, accusing the government of “waging a war on comfort” and pandering to “eco-elites.” They demand tax breaks for AC purchases, framing it as a matter of personal freedom. Meanwhile, the Greens have launched a campaign called “Cool Without the Coal,” pushing for regulations to ban new AC installations in favour of passive solutions.
For the average French worker, the divide is felt most keenly. Marie Lambert, a 42-year-old teaching assistant in a Parisian suburb, has no air conditioning at home. “It’s unbearable. I lie awake at night, and then I have to teach children who are also exhausted. They say we should use fans, but fans just blow hot air. The government talks about ecological transition, but that means nothing when you can’t sleep.”
The British passive cooling innovation offers a glimmer of hope, but it faces an uphill battle. The French Construction Federation has already warned that any mandatory measures could be “unrealistic and expensive.” Yet as the heatwaves become more frequent and intense, the need for a sustainablecooling solution grows more urgent.
The divide over air conditioning is a prism through which France’s deeper social and political fractures are visible. It is a tale of two Frances: one that can afford to stay cool, and one that cannot. And as the mercury rises, so does the tension.
