Opinion Piece: Europe's 'Air Conditioning Politics'

36°C, 44.3°C, 40°C—this June, Europe was hit by a record-breaking heatwave. Temperatures in the UK soared past 36°C, while Pissos, a small town in southwestern France, recorded 44.3°C. Paris saw consecutive days nearing 40°C, and in Belgium, railway tracks visibly warped due to extreme heat. The World Health Organization reports over 200,000 heat-related deaths in Europe over the past four years. Since June 21, this heatwave alone has caused over 1,300 excess deaths across Europe, with France recording over 1,000 excess deaths in just three days starting June 24—85% of whom were over 65. France’s Ministry of Health confirmed a 40% rise in home deaths, and two central Paris funeral homes are already at full capacity.

In developed European nations, why are so many dying from heat? Most European households endure extreme heat not because they can’t afford air conditioning, but because installing AC has long been viewed as conflicting with environmental values.

Is installing air conditioning during extreme heat an act of selfishness? This dilemma has sparked fierce debate in the UK. Opponents argue that air conditioning contributes about 4% of global greenhouse gas emissions; if its use risks worsening climate change, it should come at a cost. In Camden, London, a resident was ordered to remove a newly installed AC unit, with officials suggesting opening windows as the alternative. In May, a primary school student in Nîmes, France, suffered heatstroke due to high classroom temperatures. Parents raised funds to install five portable AC units, only for the mayor to order their removal, citing concerns over creating 'inequality' with schools in poorer conditions. Absurd? Yet such cases repeatedly reveal the same truth: when life safety clashes with environmental ideals, decision-makers often prioritize the latter.

Ironically, this contradiction extends to EU leadership. During the heatwave, the EU headquarters shut down AC on floors 1–7 due to cooling system overload, while upper floors housing top officials like Commission President von der Leyen kept their AC running—sparking employee outrage. France’s Minister for Ecological Transition questioned whether AC units could prevent forest fires or animal deaths, only for media to later reveal her own office’s AC was fully operational, turning her into a public spectacle.

The heat crisis also highlights a deeper political gap: those calling for 'shared sacrifice' are often not the ones enduring the worst heat.

This AC debate has now become a political battleground between left and right. France’s far-right National Rally proposed a 'Grand Air Conditioning Plan', advocating AC installation in all schools and hospitals and offering €20 billion in interest-free loans to help 30–40 million households purchase units. While addressing basic needs, the plan faces opposition from some left-wing politicians and environmental groups.

Paris’s deputy mayor warns mass AC installation could worsen urban heat island effects, fail to solve root causes, and derail carbon neutrality goals. Yet others counter: France emits less than 1% of global greenhouse gases—can refusing AC really alter climate change, or does it merely impose unnecessary life risks on vulnerable populations?

Beyond ideology, institutional barriers are equally significant. In Paris, many Haussmann-style buildings in historic districts are strictly protected. Installing outdoor units requires approval from a 'French Heritage Architect'; if deemed visually disruptive, installation is denied. Even in regular apartments, residents must gain majority approval at an annual co-ownership meeting—missing one means waiting a year. After approval, a municipal declaration and a one-month review follow. If noise exceeds legal limits post-installation, removal may still be ordered.

On top of these hurdles, a basic AC unit with installation costs €1,500–3,000; multi-split systems for entire homes can exceed €4,000–5,000—no small sum for Europeans with a median annual income of around €20,000.

Underlying this debate is a deeper energy infrastructure issue. According to energy think tank Ember, the EU is rapidly phasing out traditional energy. Wind and solar now supply about 30% of electricity, nuclear about 23%, and fossil fuels under 30%. While this appears a strong environmental transition, during heatwaves, hydropower and wind generation both dropped, forcing reliance on expensive imported natural gas. Peak electricity prices rose over 11%.

Even nuclear power isn’t immune. High temperatures warmed river water, forcing some French nuclear plants to reduce output or shut down due to cooling water shortages. France’s Court of Auditors warns heatwave-related nuclear losses may grow. In renewable-heavy UK and Germany, the situation is clearer: during peak heat, the UK paid over ten times its usual price (€470/MWh) to import emergency power from continental Europe, and Germany paid similarly (€545/MWh). These costs ultimately land on consumers’ electricity bills.

More fundamentally, Europe’s existing power grid was designed for the 20th century’s centralized fossil fuel and nuclear systems, not today’s decentralized, intermittent wind and solar. High temperatures cause power lines to sag and resistance to rise, forcing grid operators to reduce load. A substation in northwest France shut down due to overload, cutting power to tens of thousands. Milan and Turin faced widespread blackouts.

Imagine if European governments relaxed AC restrictions, raising adoption from today’s ~20% to the 90% seen in the US and Japan. Current power infrastructure would struggle to cope even now, let alone in the future.

This is the core of the 'air conditioning debate': while environmental ideals matter, balancing them against basic human safety is far more urgent than debating who is right. Europe must confront not just ideological debates, but whether its current energy policies and power infrastructure can withstand future extreme climates—and the rising electricity demands of AI.
