As Europe grapples with an unprecedented spell of extreme heat, a long-standing reluctance to adopt air conditioning is increasingly coming under scrutiny. Temperatures have crossed 40 degrees Celsius in several parts of France, Spain, Italy and Germany, disrupting daily life, forcing school closures, straining hospitals and exposing the continent’s limited preparedness for rising temperatures.
Unlike the United States, where air conditioning is a standard feature in most homes, Europe has historically relied on natural ventilation and traditional cooling methods. According to the International Energy Agency, only about one in five European households has air conditioning, compared with nearly 90% of homes in the US. The gap is rooted in Europe’s cooler climate, where buildings were designed to retain heat during long winters rather than stay cool during prolonged summers. However, with Europe warming nearly twice as fast as the global average, those architectural advantages are increasingly becoming liabilities.
Many of Europe’s older buildings feature thick walls and compact windows that trap heat during heatwaves, while newer glass-fronted structures often intensify indoor temperatures by acting like greenhouses. Despite the growing need for cooling, installing air conditioning remains a complicated and expensive affair in many cities. Heritage conservation rules frequently prevent residents from placing outdoor condenser units on historic buildings, while strict aesthetic regulations in urban areas often delay or block installation requests altogether.
Cost is another major hurdle. Installing a standard split air-conditioning system can exceed €1,000, while more energy-efficient heat pump systems can cost several thousand pounds even after government subsidies. On top of installation expenses, Europe’s comparatively high electricity prices discourage many households from running cooling systems regularly. As a result, many residents continue to tolerate short periods of extreme heat rather than invest heavily in air conditioning.
The issue has also evolved into a broader political and cultural debate. In France, some political leaders have argued that wider access to air conditioning is essential to protect public health during increasingly severe heatwaves. Others contend that expanding air-conditioning use would increase electricity consumption and greenhouse gas emissions, making climate change even worse. Climate experts argue that presenting the issue as a simple political divide overlooks the need for comprehensive climate adaptation strategies, including better urban planning, improved building design and increased green spaces.
Beyond politics, cultural attitudes continue to shape public opinion. Many Europeans traditionally view air conditioning as unnecessary or even excessive, contrasting with the American tendency to prioritise indoor comfort. This outlook is partly influenced by generations that experienced hardship and resource scarcity, making energy-intensive cooling systems seem extravagant. Environmental concerns reinforce these attitudes, with surveys indicating that a large majority of people in countries such as France believe widespread air conditioning harms the environment.
Nevertheless, experts point out that the environmental impact of air conditioning depends largely on how electricity is generated. Countries like France, which rely heavily on nuclear power, produce relatively low-carbon electricity, reducing the emissions associated with cooling. At the same time, cooling demand already accounts for a significant share of global electricity consumption, and energy use for cooling buildings across the European Union has risen sharply in recent years.
Researchers also caution that air conditioners alone cannot solve the problem. Studies suggest that large-scale use of air-conditioning units can raise outdoor temperatures in densely populated urban areas by releasing waste heat, making surrounding streets even hotter. Experts therefore advocate a balanced approach that combines efficient cooling technologies with passive measures such as better insulation, shaded streets, green infrastructure, improved ventilation and climate-resilient urban planning.
As climate change continues to drive more frequent and intense heatwaves, Europe is increasingly confronting the challenge of balancing public health, environmental sustainability, heritage conservation and energy efficiency. The continent’s traditional resistance to air conditioning is gradually giving way, but policymakers and urban planners face mounting pressure to develop long-term solutions that protect residents without undermining climate goals.
