Germany
Moderate combined riskNew national heat record of 41.8°C set in June 2026; heat-related deaths this year already exceed any full year since 2016.
For every €100 of economic output, the state already owes €64 — and most homeowners would pay storm and flood damage out of pocket.
2021 riverine flood (Ahr valley): ~€32.7bn — over 75% of all German losses since 2015
Country Vulnerability Index: 4.6/10
System: Voluntary, no mandatory system (41% of homes lack natural-hazard cover)
Trend: Mandatory insurance included in coalition agreement, design still open
France
Moderate combined riskDrought has quietly overtaken flood as France's main Cat-Nat cost driver: it made up 42.2% of natural-disaster losses since 1982, and over 50% of payouts in most recent years, as drying clay soils crack building foundations nationwide.
France insures nearly everyone against disasters, but the risk mix behind that safety net is shifting from flood to drought — and the state is raising the price of coverage as claims climb either way.
2021 cold wave: ~€5.0bn
Country Vulnerability Index: 5.3/10
Flood still leads over 1982–2024 (51.5%), but drought (soil subsidence damaging building foundations) has overtaken flood in most years of the last decade and made up over 50% of annual Cat-Nat payouts recently. 2025 losses: ~€1.7bn, of which €770m–1bn from drought alone. Source: SDES (Ministère de la Transition écologique) and CCR annual report, 1982–2025.
System: CatNat, mandatory, 98% coverage
Trend: Surcharge raised 12%→20% as of Jan 2025, driven by both flood and a fast-growing drought/subsidence bill — fiscal strain per Court of Auditors
Italy
High combined riskRepeated hail, flood and landslide damage in 2026 continues to concentrate in Lombardy, Veneto and Emilia-Romagna — the northern region generating roughly 55% of Italy's GDP. Emilia-Romagna alone saw three major flood events in 2023–2024, including one that submerged ~550km² and caused an estimated €7bn in damage.
Debt is the highest of the four, four out of five euros in storm damage go uninsured — and the damage is landing in the industrial north, not the periphery, which is exactly where Rome's tax base sits. State and EU funds have covered less than a fifth of landslide and flood damage since 2015.
2023 riverine flood (Emilia-Romagna): ~€8.9bn
Country Vulnerability Index: 6.3/10
Landslide and flood damage since 2015 exceeds €19bn (Greenpeace analysis of Protezione Civile data); national and EU solidarity funds covered only ~17% of it (~€4bn combined). Regional coverage varies sharply: Lombardy 18%, Emilia-Romagna 17%, Piedmont 16%, Sicily/Veneto 15%, Campania just 7% despite the second-highest damage total. Landslide-prone area grew 15% in three years (2021–2024: 55,400km² → 69,500km², now 23% of national territory); 94.5% of Italian municipalities face landslide, flood, coastal erosion or avalanche risk.

System: Mandatory for businesses since 2024, still voluntary for households — under 20% insurance density overall
Trend: No comprehensive residential system, unlike France or Spain
United Kingdom
Lower combined riskOver 6 million English homes already sit in areas at flood risk; that figure is projected to reach 8 million by 2050.
Debt sits close to one year of national output; flood cover exists, but only for a small, subsidised slice of homes.
System: Flood Re, hybrid, flood cover only
Trend: Scheduled to end in 2039, gap could widen afterwards
Spain
Moderate combined riskThe October 2024 Valencia DANA floods caused an estimated €3.5bn in insured losses and over 225,000 claims — the CCS paid out around 80% of total losses within four months. 2026 has brought both extreme heat and windstorm damage across the country.
Spain runs one of Europe's oldest and most comprehensive catastrophe insurance systems — 83% of households have some form of cover, well above Germany's 54%. Note the gap figure below measures uninsured households, not uninsured losses like the other four countries, so it isn't directly comparable to them.
The Consorcio de Compensación de Seguros paid out €10.6bn for extraordinary risks between 1987 and 2022, roughly 70% of it flood-related — a track record of actually paying claims, not just underwriting them. Insurance density in Spain is 83% (cepStudie 2025), higher than Germany's 54% but below France's 98%. Note this is a different metric from the loss-based 'protection gap' used for the other countries here: density measures the share of households with any policy, not the share of economic losses left uncovered. Average combined loss ratio for Spanish home insurance, 2014–2023: 94%.

System: Consorcio de Compensación de Seguros (CCS), state monopoly with unlimited government guarantee, automatically bundled into property policies since 1941 — 83% insurance density (cepStudie 2025), though buying a policy itself isn't compulsory unless there's a mortgage
Trend: CCS paid out €10.6bn for extraordinary risks 1987–2022, ~70% of it flood-related; average combined loss ratio for home insurance 2014–2023 was 94%
No European system has yet solved this trade-off: France covers almost everyone but at rising cost to taxpayers; the UK covers a narrow slice cheaply, with an expiry date; Germany and Italy leave the bill largely to households. As storms and heatwaves become more frequent, the choice for every country is the same — pay for prevention and shared insurance now, or pay for recovery later, and less fairly.

Data note: the €43.8bn German loss figure is dominated by a single event — the July 2021 Ahr valley flood. It is not an annual average.
