France faces the largest estimated national impact in the Triodos analysis. The bank calculated a 1.4 percentage-point reduction in French GDP growth, putting estimated full-year output at about minus 0.6%. Italy and Spain also face substantial losses, while Belgium shows a smaller impact. In the Netherlands, the bank estimated a 0.8 percentage-point reduction in growth, leaving economic activity broadly flat. Poland shows less exposure because the analysis assumes fewer exceptionally hot days there.
