The Financial Toll of Extreme Weather

French insurers faced a significant financial burden in 2024, with climate-related events costing them a total of €5 billion. While this figure is below the 2020-2024 average of €5.6 billion, it significantly exceeds the €1.5 billion average recorded between 1982 and 1989.This places 2024 as the ninth most expensive year for insurers since the establishment of the natural disaster compensation scheme in 1982.

These escalating costs underscore the increasing vulnerability of france to extreme weather phenomena,a trend mirrored globally. According to a recent report by the World Meteorological Organization, the past decade has been the warmest on record, leading to more frequent and intense weather events.

Breakdown of Insurance Claims

A detailed analysis of the €5 billion in claims reveals the following:

• Storms, Hail, and Snow: €2.2 billion
• Natural Disasters (Floods and Droughts): €2 billion
• Harvest Insurance: €800 million

It’s critically important to note that storms and hail are typically covered under standard damage contracts, while floods and droughts fall under the “cat nat” (natural catastrophe) scheme. Under this scheme,the French government covers half of the costs,reducing the financial strain on insurers.

Specific Events and Their Impact

Several important weather events contributed to the high insurance payouts in 2024:

• storms Kirk and Leslie, and Cévenols and Mediterranean Episodes (October 2024): €785 million
• Floods in North and Pas-de-Calais (November 2023 – January 2024): €430 million
• Cyclones in Overseas Territories (Belal, Garance, and Chido): Over €1 billion, with cyclone Chido in Mayotte alone accounting for €500 million.

These events highlight the diverse range of climate-related risks facing France,from severe storms and floods in the mainland to devastating cyclones in its overseas territories.

The Rising Tide of Water Damage Claims

France experienced a particularly rainy year in 2024, with the lowest amount of sunshine in over two decades. This led to a 12% increase in the frequency of water damage claims, especially in regions with the highest rainfall.These rain surpluses generate a high risk of remonstation-clay withdrawal (RGA), which makes the buildings crack, in the event of a strong drought during the summer of 2025, warns France Insurers.

The increase in water damage claims is a long-term trend. Over the past 20 years, compensation for water damage has more than doubled (+134%) due to both increased frequency and higher average claim costs. In 2024, water damage claims represented the largest category of claims in home insurance.

In 20 years, water damage compensation has more than doubled (+134%) due to the increase in the frequency and the average cost of claims.

Looking Ahead: Preparing for Future Climate Risks

The escalating costs of climate-related events underscore the urgent need for proactive measures to mitigate future risks. This includes investing in infrastructure improvements to reduce flood vulnerability, implementing stricter building codes to withstand extreme weather, and promoting sustainable land management practices to minimize the risk of soil erosion and landslides. Furthermore, continued research and advancement in climate modeling and forecasting are crucial for anticipating and preparing for future climate challenges.
