The Business of Keeping Europe Cool

For decades, Europe treated air conditioning as something faintly un-European, an American excess to be looked down on from a shaded café. That attitude is collapsing in real time, and it is turning the European air conditioning market into one of the largest adaptation opportunities of the decade.

The demand is already frantic. Air-conditioner sales through German e-commerce channels rose about 37% in a single month year on year, while shipments in Spain and France more than doubled. Demand for one popular portable unit ran so hot that second-hand prices climbed above the cost of a new one. A continent that spent years insisting it did not need cooling is now buying it in a panic.

The interesting question for anyone in business is not whether Europe will cool itself; it plainly will. The real question is who captures the money while it does, and the answer reaches far beyond the air conditioner.

A Cost That Has Become Permanent

Behind the buying spree sits a hard economic shift. Europe is the world’s fastest-warming continent, with temperatures up around 2.4°C over the past five years, almost twice the global average.

The bill is already enormous. Heat, drought, and flooding cost European economies nearly $50 billion in a single recent year, most of it lost productivity. One projection puts the cumulative cost to Europe’s largest economies at $638 billion by 2030.

The shift that matters is in how this is now classified. The trade-credit arm of the insurer Allianz has called extreme heat a structural economic risk, with Europe highly exposed. Once a cost stops being treated as a freak event and starts being modelled as a recurring line item, it stops being merely a loss and becomes a market, and several distinct markets are now forming around it at once.

The Air Conditioning Market Is the Loud, Easy Win

The fastest money is flowing to the companies that already make cooling at scale, almost none of which are European.

Asian manufacturers such as South Korea’s Samsung, China’s Midea, and Japan’s Mitsubishi Electric are enjoying a windfall as Europe scrambles for relief. They built their businesses in markets where air conditioning is standard across homes, offices, and transport, so they had the products and the production lines ready the moment European demand spiked.

This is the obvious response to a hot continent, and it is also the shallowest. The profit from shipping more units largely leaves Europe, and the units themselves carry a sting in the tail. Air conditioners and electric fans already consume about a fifth of all the electricity used in buildings worldwide, and the International Energy Agency expects cooling to become one of the single largest drivers of global electricity demand over the coming decades. More heat drives more air conditioning, which strains the grid and adds emissions, which drives more heat.

The air conditioning market is real and growing fast, but on its own it is a treadmill. The more interesting businesses are the ones built around not needing to run the compressor in the first place.

Why Do So Few European Homes Have Air Conditioning?

Fewer than one in five European homes has air conditioning, against roughly 90% in the United States, for the simple reason that Europe never used to need it. Summers were mild enough that the cost and the cultural distaste outweighed the benefit, and the building stock was shaped by that assumption. The largest and most durable opportunity now lies in undoing it.

More than 85% of the European Union’s buildings were constructed before 2001, most of them designed for a climate that no longer exists, with heavy reliance on single glazing, dark roofs, and no shading. Cooling Europe is therefore less an appliance problem than a renovation problem, and the renovation has to happen across hundreds of millions of existing structures.

That is why investors moved into European building-efficiency names when the red alerts spread: the materials group Saint-Gobain, the refrigeration and HVAC wholesaler Beijer Ref, the heat-pump maker NIBE Industrier, the heating-and-cooling firm Ariston, and the insulation manufacturer Rockwool. Insulation, reflective and green roofs, external shading, smart glazing, and heat pumps are all part of the same wave. A Morningstar analyst added a note of realism, observing that while the heat strengthens the long-term case for these firms, it is unlikely to move their earnings or share prices in the near term. The retrofit is a decade-long build, not a summer trade, which is exactly what makes it durable.

Beneath the listed giants, a layer of startups is attacking the same problem with new technology. Some are building cooling that uses no synthetic coolants and claims to undercut conventional air conditioning on price by up to half. Conry Tech raised seed funding for a modular system it says can halve a commercial building’s energy bill by distributing small units instead of running one central chiller. District and geothermal cooling networks, which pipe cooling through a neighbourhood the way gas once flowed, add another layer with a built-in local-jobs story.

Cooling as Infrastructure

Step back from the building and a bigger market appears: cooling as a shared system rather than a private appliance.

The same surge in cooling demand that is filling shops with portable units is also straining the electricity grid, which turns grid storage, demand management, and backup capacity into adjacent businesses. The strain runs both ways with the AI boom, because the data centres now spreading across Europe are themselves enormous heat problems that need constant cooling, putting industrial cooling, liquid-cooling systems, and energy management at the centre of two megatrends at once.

Even the supply of electricity is exposed. During past heatwaves, French nuclear plants had to cut output because the rivers they rely on for cooling ran too warm, tightening supply and spiking power prices. Every one of those constraints is a market for someone, whether in storage, efficiency, or alternative cooling.

The Market for Keeping Workers Working

The clearest productivity loss from heat falls on people who work outdoors or in hot buildings, and a whole protective economy is forming around them.

Employers are equipping staff with cooling vests, water-activated wrist coolers, cooling towels, and ventilated headgear, and governments are starting to subsidise the spend. New York’s state insurer launched an Extreme Heat Equipment Credit that lets small businesses cut their workers’ compensation premiums by up to $1,000 when they buy heat-protective equipment. Where a government underwrites demand like that, a supply industry follows.

Above the gear sits a software and monitoring layer. Solar installers are already using wearable thermometers, and firms are deploying heat-stress sensors and scheduling tools that shift labour to cooler hours. The stakes are large enough to justify the spend: the International Labour Organization projects that agriculture alone will account for 60% of global working hours lost to heat stress by 2030. Anything that claws back a fraction of those hours has an obvious buyer.

What Is Parametric Heat Insurance?

Parametric heat insurance pays out automatically when temperatures cross an agreed threshold, rather than after a slow, assessed claims process. If heat is now a structural risk, someone has to price it, and this is how finance is starting to.

The model is already live. In India, migrant and gig workers have received heatwave-linked payouts through schemes run by insurers and non-profits, and the model is spreading. One Indian broker reports that nearly every company with a large gig workforce is now exploring heat-risk cover. The same instinct that put climate risk into mortgage pricing and catastrophe bonds is now being applied to temperature, and parametric payouts double as a planning tool, letting an employer fund extra staff to cover shortened working days.

This is the quiet, lucrative end of the adaptation economy. It does nothing to cool anyone down; it simply turns the volatility of heat into a product, and volatility has always been something finance is happy to sell.

The Ripple Into Food and Travel

Two further markets sit one step removed from cooling but move with it.

Heat curtails crop yields and has already fed measurably into European food prices, which pushes money toward heat-resistant seed, cold-chain logistics, and controlled-environment indoor farming. And the tourism map is shifting, as the classic Mediterranean summer becomes punishing enough to nudge travellers north and into the shoulder seasons, rerouting billions in holiday spending and rewarding whoever positions for the cooler destinations and the cooler months.

Beyond the Air Conditioner

The winners in the European air conditioning market will not be whoever sells the most air conditioners.

That prize, the rush of portable units off the shelves, is real but shallow, and most of the cash flows to Asian manufacturers who were ready first. The deeper and more defensible businesses are spread across the retrofit of the building stock, the cooling of the grid and the data centre, the protection and scheduling of the workforce, the pricing of the risk, and the slow reshaping of where Europe grows its food and takes its holidays.

Europe spent decades convinced it did not need to think about staying cool. It now has to adapt an entire economy to a climate it was not built for, and that adaptation is the fastest involuntary retrofit of a rich region in modern memory. The air conditioner is merely the noisiest thing being sold. The lasting money belongs to whoever understood that the real market was the heat itself, and everything a society has to buy to keep functioning inside it.
