France’s historically hot summer will cost the country between €10 billion and €15 billion, the equivalent of up to 0.5 percent of gross domestic product, according to preliminary estimates from Minister for Ecological Transition Monique Barbut.
Barbut shared the figures on Wednesday, cautioning they should be treated “with great caution” as they are based on an extrapolation of heat-related costs compiled by France’s official statistics agency Insee in previous years. She warned the figure could rise as temperatures remain well above seasonal averages across many French regions.
Wildfires and Crop Failures Drive Costs
The minister identified recent wildfires and drops in agricultural output as the biggest estimated costs, warning they would continue to grow if governments fail to implement policies to limit the impacts of climate change. Eighty-five percent of France was under drought warnings as of mid-July, compounding the damage from months of extreme heat.
France’s August 2003 heatwave, which until this summer was the warmest ever recorded in the country, led to a 22 percent drop in cereal production and a 9 percent drop in wine production, according to Insee. The current summer has already surpassed those temperature records, raising concerns that agricultural losses could be even more severe.
Broader European Economic Impact
The economic toll extends beyond France. A separate analysis estimated that extreme heat could cost EU economies around €180 billion this year, roughly 1 percent of GDP and almost exactly the growth the bloc had been expecting for 2026. France faces the heaviest blow among the larger member states.
A 2025 report from the European Central Bank found that regions hit by heatwaves and droughts experienced noticeable impacts on economic output, with effects persisting well beyond the immediate weather events. The findings underscore growing concerns about the economic resilience of European economies to climate-driven shocks.
