Climate Change Is Making Parts of Europe Uninsurable

Full text

BRUSSELS — As wildfires menaced the outer suburbs of Bordeaux and Madrid this week, Europe once more faced an uncomfortable reality: a rapidly warming planet threatens to make parts of the continent uninsurable.

The record-breaking blazes — which have forced hundreds of thousands to flee their homes, destroyed wildlife and threatened cities once thought immune to wildfire — are the latest in a series of climate-related natural disasters that are forcing policymakers to rethink how to handle the risk.

The answer, increasingly, is a brutal one: Either governments step in to protect citizens from soaring insurance premiums, straining public budgets; or people face being left with no protection at all when their homes are flooded or burn down.

The growing risk has prompted the European Central Bank and EU insurance regulator to call on Brussels to take a more active role by setting up an EU-level reinsurance scheme and a public natural disaster fund.

“What’s happening in Europe this summer isn’t unique,” deputy governor of the Bank of France Agnès Bénassy-Quéré said. “These heatwaves and forest fires are part of a marked global increase in extreme weather events that imposes real costs on households, businesses, and governments,” she said.

Wildfires are “the fastest-growing weather peril globally,” even if they have “so far contributed only a relatively small share of insured losses in Europe,” said Nikhil da Victoria Lobo, who leads reinsurance giant Swiss Re’s Property & Casualty Reinsurance business for western and southern Europe, the Middle East and Africa.

Extreme weather events already cost a fortune in repairs for Europe’s cash-strapped governments. Data from the European Environment Agency shows weather-related extremes cost the EU economy over €200 billion in economic losses between 2021 and 2024.

Insurance firms, meanwhile, are hiking their prices and even pulling out of certain at-risk areas, leaving governments and individuals to bear the cost of uninsured losses.

“In Europe, 75 percent of the damages related to natural disasters are not insured,” said Ariel Le Bourdonnec, a campaigner working on insurance at the NGO Reclaim Finance, citing data from the European Insurance and Occupational Pensions Authority. For insurers, flooding and storms are the most costly natural disasters, followed by extreme heat and wildfires, according to Insurance Europe.

Experts predict it’s only going to get worse . As fossil fuel use continues to increase globally, temperatures are rising at an unprecedented rate, disrupting the planet’s climate and ecosystems. Global warming causes more weather extremes like wildfires, floods and droughts.

“Insured wildfire losses in Europe have increased by an estimated 8 to 11 percent per year in real terms since 1970,” added SwissRe’s da Victoria Lobo.

Damages pile up

In France, where a massive wildfire still burns in the south-west Gironde and Landes departments, the government has promised that insurance companies will cover the accommodation costs and the damages for over 200,000 people who have been evacuated.

At least 240 homes have been lost in the fire so far. Wildfires are covered by home insurance, and the government has promised to streamline the process, meaning most of the victims should receive money to rebuild their houses. “Insurers are playing the game,” Industry Minister Sébastien Martin told RMC on Tuesday.

But wildfires will also have a direct impact on France’s already strained public finances for reforestation, reconstruction and for unemployment benefits paid to companies that have been forced to put their activities on hold.

In the Gironde department, around 130,000 workers are currently unable to work because of the wildfires, and 13,000 businesses have been evacuated.

Martin ruled out a massive subsidy plan, calling for “a concrete, targeted and precise response,” adding that it was too early to quantify the economic damage caused by wildfires.

Still, the French environment ministry estimates that reforestation efforts to cover all the land lost to fires in the country this year could cost €1 billion.

The Spanish insurance firm Mapfre said on Monday that it had received 116 claims so far, mostly related to home insurance. A spokesperson for the company said that the fires “are not expected to have a significant economic impact.”

Pushed out

But the cumulative effect of climate-related natural disasters continues to put pressure on insurers. With every fresh disaster, primary insurers need to ratchet their premiums to avoid making losses on new policies.

In some parts of Europe, “the peak risks are becoming a reality. Even the reinsurers themselves, who are supposed to protect the insurers, are pulling back, reducing their coverage, or imposing deductibles, which we call retentions, that are getting higher,” said Thierry Langreney, president of the climate NGO Les Ateliers du Future .

Tourist industry body SKÅL International, citing national data, says that premiums for tourism businesses in Spanish areas prone to wildfires have risen by 15 percent annually over the past five years, while premiums for coastal properties in Italy rose 25 percent in the five years through 2022 due to more frequent storm surges and flooding.

According to the French insurance lobby France Assureurs, home insurance premiums already increased by 7.8 percent in 2025, while the climate disaster premium — which doesn’t cover wildfires — rose by 66 percent.

For now, most French residents can still easily obtain home insurance anywhere in mainland France, according to the public reinsurer. But it is seeing early signs of strain in a few cities, where insurance is becoming harder to obtain, or increasingly unaffordable.

Bit by bit, such trends push the cost of insurance beyond what businesses or households can afford, leading to an ever-wider ‘protection gap’. Around half of global economic losses from natural disasters were uninsured last year, according to insurance giant Aon.

“There is a real risk that this already sizeable gap could widen further as natural catastrophes increase, with serious consequences for people’s daily lives and for economic activity in affected regions,” said Petra Hielkema, who chairs EIOPA, during a conference on climate risk last April.

As a result, governments often have no choice but to act as a backstop, increasing public spending and debt, according to a recent study by the Network for Greening the Financial System, which brings together central banks and financial supervisors from across the world.

“The negative effects are felt via a higher cost of insurance coverage in following years, or higher public debt,” said the report, which identified negative financial consequences of recent natural catastrophes on GDP, inflation and the credit system.

“Sometimes the private sector bears the brunt of the burden, other times the damage appears in public finances. But ultimately, these events are costly for the countries struck by them, and beyond,” said Benassy-Quéré of the Bank of France.

Change the system

The European Central Bank and EIOPA have proposed addressing the problem via a new EU public-private reinsurance scheme and a new EU fund for public disaster financing.

The European Commission is expected to present a package of climate resilience and risk management measures later this year.

“Public authorities must continue providing emergency support, but Europe should also develop common financial instruments that strengthen solidarity and help share climate risks across member states,” said César Luena, a Spanish socialist MEP.

“The future European Climate Adaptation Framework should include a European climate reinsurance or risk-pooling mechanism,” he said.

In France, other climate disasters are covered by a public-private system that makes climate insurance mandatory and spreads the risk between insurers and the state.

“The mechanism comes down to subsidizing the insurance contract located in the areas most exposed by a margin that insurers take from the mandatory insurance in less exposed areas at a rate set by the State,” said Langreney, who advised the French government back in 2024 on how to update the model.

“It’s probably a good practice that’s essential to adopt for other European countries that would like to make insurance more widespread,” he added.

Insurers, meanwhile, want to see more action taken on prevention. Countries should “stop developing assets in high-risk areas” for “fire-prone areas, but also to flood-prone areas,” said Tobias Grimm, chief climate scientist at Munich Re.

Some groups like Reclaim Finance also argue that large insurance firms should foot a larger part of the bill since their profits are going up. “There’s a portion of these damages that’s not covered; this portion keeps growing, and on the other side you have insurers whose profits keep increasing,” Le Bourdonnec said.
