Extreme heat is emerging as one of the most underestimated occupational hazards in the European Union, as the climate crisis increases the frequency, duration, and intensity of heatwaves. According to data cited by To Vima, workplace deaths linked to rising temperatures have increased by 42% in the EU since 2000.
Experts warn that high temperatures are also associated with an increase in workplace accidents. When temperatures exceed 30°C, the risk of an accident rises by 5% to 7%, while above 38°C, the likelihood of an accident increases by 10% to 15%.
At the same time, the number of workers exposed to heatwaves across EU countries has increased by 60% over the past two decades. Despite the seriousness of the situation, the institutional response remains limited.
The European Trade Union Confederation says these deaths are preventable and is calling for EU legislation instead of non-binding guidelines.
Across Europe, although 47% of workers say they have experienced excessive heat in the workplace, only 15% report that protective measures have been implemented by employers, despite the guidelines issued by the European Commission in 2023.
Greece is a particularly high-risk case due to prolonged summer heatwaves. According to data from OSETEE, 22 worker deaths in 2025 can be linked to excessive heat.
The European Trade Union Confederation argues that these deaths are not “accidents,” but predictable and preventable incidents, calling for binding European legislation instead of simple recommendations.
