Extreme heat and drought across Europe could erase approximately 1% [1] of the European Union's gross domestic product this year, Triodos Bank said.
The forecast highlights how climate-driven weather events now pose a direct threat to macroeconomic stability by disrupting energy production and labor output.
Triodos Bank said the brutally hot summer is set to cost the EU economy €180 billion [2], a figure equivalent to roughly 1% [1] of the bloc's GDP. Other estimates place the monetary loss at $208 billion [3] or 295 trillion won [3].
The bank identified two primary drivers for the economic decline. First, extreme temperatures reduce worker productivity as heat stress limits labor capacity. Second, droughts lower the output of nuclear power plants, which rely on water for cooling, a critical vulnerability for the region's energy grid.
France is expected to be the hardest hit of all EU member states. Triodos Bank said repeated heatwaves could potentially push the French economy into contraction [4].
While some reports suggest these losses could erase growth expected for 2026 [5], the bank's primary warning focuses on the immediate impact of the current summer's weather patterns. The report was published on Saturday, Aug. 10 [1].
The findings suggest that the intersection of energy dependence and climate volatility creates a fragile economic environment. As temperatures rise, the cost of maintaining industrial output and power stability increases, leading to the projected billions in losses.
“The extreme heat and drought could erase up to 1% of EU GDP this year.”
This forecast indicates that climate change is no longer just an environmental concern but a systemic financial risk. By linking nuclear power stability and labor productivity directly to temperature thresholds, the report shows that the EU's economic growth is increasingly vulnerable to seasonal weather extremes.
