Climate change is abstract. The economic cost is not. ClimateCost makes visible what states, insurers and citizens in Germany, France, the UK and Italy ultimately bear.

Germany

Moderate combined risk
Right now

New national heat record of 41.8°C set in June 2026; heat-related deaths this year already exceed any full year since 2016.

Active weather warning — Severe

For every €100 of economic output, the state already owes €64 — and most homeowners would pay storm and flood damage out of pocket.

Government debt-to-GDP 64.4%
2026-Q1
Natural-hazard insurance gap 57%
No state backstop
Actual losses since 2015 €43.5bn

2021 riverine flood (Ahr valley): ~€32.7bn — over 75% of all German losses since 2015

Country Vulnerability Index: 5.0/10

System: Voluntary, no mandatory system (41% of homes lack natural-hazard cover)

Trend: Mandatory insurance included in coalition agreement, design still open

France flag

France

Moderate combined risk
Right now

Drought 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.

Active weather warning — Moderate

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.

Government debt-to-GDP 117.6%
2026-Q1
Natural-hazard insurance gap 46%
State-backed, mandatory
Actual losses since 2015 €15.0bn

2021 cold wave: ~€5.0bn

Country Vulnerability Index: 5.7/10

Drought share of Cat-Nat losses 42.2%

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 flag

Italy

High combined risk
Right now

Repeated 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.

Active weather warning — Severe

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.

Government debt-to-GDP 138.9%
2026-Q1
Natural-hazard insurance gap 78%
No state backstop
Actual losses since 2015 €28.5bn

2023 riverine flood (Emilia-Romagna): ~€8.9bn

Country Vulnerability Index: 6.4/10

Damage vs. state coverage, 2015–2024 17%

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: Voluntary, no mandatory system

Trend: Highest gap of the four countries

United Kingdom

Lower combined risk
Right now

Over 6 million English homes already sit in areas at flood risk; that figure is projected to reach 8 million by 2050.

No active warnings

Debt sits close to one year of national output; flood cover exists, but only for a small, subsidised slice of homes.

Government debt-to-GDP 94.1%
July 2026
Natural-hazard insurance gap 10%
Partial (flood only)

System: Flood Re, hybrid, flood cover only

Trend: Scheduled to end in 2039, gap could widen afterwards

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 €43.5bn German loss figure is dominated by a single event — the July 2021 Ahr valley flood. It is not an annual average.
