Dutch economy loses €9.2 billion to summer heat
Extreme heat cost the Dutch economy an estimated 9.2 billion euros this summer, according to credit insurer Allianz Trade (PDF). Only Italy, Germany, France and Belgium recorded larger losses in Europe. The outcome is notable because the Netherlands was hit almost as hard as countries much further south. Allianz points to weak climate adaptation and unusually low water levels on the river Rhine as key reasons behind the damage.
Why did the heat hit the Dutch economy so hard?
The main reason is lost productivity. People work less hard when it is hot, so building work slows down and less is grown or produced per hour. Allianz calculates that this productivity loss makes up most of the 9.2 billion euro figure. Italy, Germany and France lost even more, at 27.8 billion, 25 billion and 20.1 billion euros respectively, while Belgium lost 9.4 billion euros. The Netherlands and Belgium stand out on this list because they are small economies compared with the others.
What role did low water levels on the Rhine play?
A second factor was the exceptionally low water level of the Rhine this summer. The river is vital for Dutch companies that transport goods to the German Ruhr region. Extra lorries only partly made up for the lower river capacity. Transport took longer and diesel became more expensive, and many planned transports did not go ahead at all. This added further pressure on productivity across the wider economy.
Why did the Netherlands do worse than expected?
According to Allianz, the Netherlands is simply less prepared for extreme heat than countries in southern Europe. Southern European countries have invested for longer in measures such as better irrigation systems for farming, and workers there often take a longer midday break during the hottest hours. Allianz notes that nobody expected conditions to become this extreme, with three separate heatwaves in a single summer.
What needs to change?
Insurers and investors have long argued that companies need to invest more in climate adaptation. Allianz Trade says that the Netherlands lags behind on relevant legislation and suggests that rest breaks and more flexible working hours could help people stay productive during heat. This is not only about people working outdoors: many Dutch factories still have insufficient insulation against heat, which adds to the economic impact.
These figures illustrate how a single summer of extreme heat can already leave a measurable mark on economic output. The estimate comes from a model that translates heat exposure directly into lost productivity, without needing visible damage to buildings or equipment: workers simply work more slowly, take longer breaks, or stay home.
