The scorching summer of 2026 has left a trail of economic turmoil across Europe, with the continent's major economies feeling the heat. From tourism to power generation and productivity, the impact of heatwaves is far-reaching and costly. Economists at the Dutch bank Triodos estimate that the total economic cost of heatwaves in the EU could reach a staggering €180 billion, with each country facing its own unique challenges. Here's a closer look at how some of Europe's key economies are faring.
France: Nuclear Woes and Wildfires
France is facing a double-edged sword. On one hand, the country's nuclear power plants are struggling to cope with the heat, leading to potential shutdowns and lost energy output. More than two-thirds of France's electricity generation relies on nuclear power, and when river temperatures around these plants soar, they must shut down to prevent overheating. This has already resulted in a 15% offline capacity on Friday, with temperatures expected to rise further.
On the other hand, France is battling widespread wildfires, which pose a significant challenge to the economy. The knock-on effects of these fires include higher prices for businesses, as the country grapples with the loss of energy output and the potential for further shutdowns.
Economists at Triodos predict that France could be one of the hardest-hit European economies, with a 1.4 percentage point knock-off GDP. This could exacerbate the country's fiscal challenges, as Paris already faces the highest interest rate in 15 years on its borrowing, amidst political wrangling over tax and spending.
Germany: Logistics in Crisis
Germany is facing a critical situation on the Rhine River, a vital freight route for the country. Low water levels have forced barges to lighten their loads, and ship traffic has been significantly reduced. This is particularly concerning for the chemical industry, as the Rhine carries the bulk of German inland waterway freight, including coal, crude oil, gas, and refined products.
Wolfgang Grosse Entrup, the head of the German chemical industry association VCI, warns that the extremely low water levels are pushing logistics and supply chains to their limits. This comes at a time when many German industrial sectors are already struggling against cut-price competition from China.
While the impact on GDP is expected to be smaller than in France, at less than a percentage point, the challenges for Germany's economy are still significant.
Spain: Tourism Resilience and Wildfires
Spain has been hit hard by devastating wildfires, with almost 275,000 hectares damaged, according to the EU's Copernicus monitoring system. However, surprisingly, the economic impact is likely to be relatively minor. Credit card data shows no clear disruption in non-resident spending, suggesting that tourism was barely affected.
The wildfires did cause a temporary fall in resident spending, but this was a direct consequence of evacuations, and spending returned to its normal level within days. Nevertheless, with an estimated 47 excessively hot days expected by the end of the summer, Spanish workers and firms will face a hit, with Triodos predicting a knock-off of almost 1 percentage point from Spain's 2.8% growth forecast.
Italy: Tourism and Agriculture in Peril
Italy's economy is heavily reliant on tourism and agriculture, making it particularly exposed to the effects of heatwaves. The agricultural association Coldiretti claims that climate impacts have already cost producers of commodities such as tomatoes, olive oil, and wine about €20 billion over the past four years, equivalent to 12.5% of the sector's output.
With more hotel beds than any other EU country, Italy could also suffer if tourists opt for cooler destinations due to the legacy of repeated heatwaves. Triodos estimates that Italy will be hit second-hardest of the EU countries studied, with a 1.1 percentage point knock-off GDP.
Over time, the effects could compound the challenges for an economy already struggling with an ageing population and high public debt. Separate research by the Italy-based climate group CMCC suggests that the country's exposure to heatwaves and drought could eventually drive up the interest rate the government pays to borrow, as investors worry about the impact on public finances.
Poland: Outlier in the Heatwave
Poland stands out as an outlier, having experienced only a few more hot days in 2026 than in a normal year. However, it has not been completely insulated from the heatwaves, with low rainfall affecting its rivers and power plants. Poland's electricity grid operator had to invoke emergency powers earlier this month, during what the prime minister, Donald Tusk, called a "very difficult period".
Despite the challenges in harder-hit EU economies, Poland is recording healthy economic growth of 2.9% this year, with little change from the European Commission's spring forecast. However, the knock-on effects of transport and energy challenges in other EU countries could still impact Poland's economy.
In conclusion, the economic cost of heatwaves in Europe is profound and multifaceted. From nuclear power plants to freight routes and agricultural sectors, the impact is felt across various industries. As the continent grapples with the consequences of a scorching summer, the need for sustainable solutions to combat the effects of climate change has never been more urgent.
