- Triodos economists estimate €180bn could be wiped off EU GDP by the heatwaves, while UK green thinktank Verdant said the heat had already cost the British economy £4.4bn by the end of July.
- France faces the worst projected GDP hit at 1.4 percentage points — pushing the economy into reverse — with up to 15% of its nuclear estate expected offline on Friday as river temperatures force shutdowns at plants that supply two-thirds of national electricity.
- Germany's Rhine river has fallen below critical levels near the town of Kaub, forcing barges to lighten loads and halting ship traffic on a route that carries coal, crude oil, gas and refined products; chemical industry association head Wolfgang Grosse Entrup warned Reuters that 'alarm bells are ringing loudly.'
- Spain has suffered the worst wildfires at nearly 275,000 hectares burned, though Oxford Economics found tourism spending was barely disrupted by the blazes, and Triodos expects heat to knock almost 1 percentage point off the European Commission's 2.8% growth forecast.
- Italy ranks as the second-hardest hit with 1.1 percentage points projected off GDP, while agricultural association Coldiretti claims climate impacts have already cost producers of tomatoes, olive oil and wine about €20bn over the past four years — 12.5% of the sector's output.
- Poland is an outlier with only slightly more hot days than a normal year, still recording healthy 2.9% growth — though low water levels on the Vistula forced power plant shutdowns and prompted PM Donald Tusk to invoke emergency powers on the electricity grid earlier this month.
Why it matters: France's projected 1.4-point GDP loss lands on an economy already paying the highest borrowing rate in 15 years amid political tax-and-spending wrangling, compounding fiscal strain. Germany's Rhine bottleneck threatens industrial supply chains already squeezed by Chinese competition, while Italy's €20bn in agricultural damage over four years signals a compounding drag on an economy with high public debt and an ageing population.
