Nearly 130 Million EU Workers Face Annual Heat Stroke Hazard, New Analysis Finds
Published on 07/08/2026 at 08:06 | Redaktion boerse-global.de
Europe is dangerously unprepared for rising temperatures in the workplace, according to a report from the European Trade Union Institute (ETUI). The analysis estimates that 130 million employees across the European Union are exposed to heat stroke risk every year, leading to approximately 277,000 hospital admissions and 230 deaths annually. The institute is pushing for binding EU-wide legislation requiring mandatory heat risk assessments at every worksite.
The World Health Organization has also sounded the alarm. Regional Director Hans Kluge noted that fewer than half of European countries have adequate heat-health action plans in place. Preliminary data suggests a June heat wave in Western Europe resulted in more than 4,000 excess deaths. In Germany, prosecutors in Cologne are investigating twelve deaths that occurred at a hospital in Leverkusen during a hot weekend at the end of June.
With the ETUI pushing for mandatory heat risk assessments across Europe, ensuring workplace hazards are properly documented is more urgent than ever. Yet many safety professionals struggle to structure their risk assessments efficiently. A free Risk Assessment Toolkit offers 41 ready-to-use checklists and templates covering everything from fire safety to lone working — helping you build a compliant, thorough risk management system.

Productivity losses mount as mercury rises
The economic toll from heat is substantial. A study by Prognos found that a single hot day in the German state of Baden-Württemberg generates costs of roughly €60 million, driven by illness-related absences, workplace accidents, and diminished performance. Market researchers at Allianz Trade observed that once the temperature exceeds 30 degrees Celsius, productivity drops by about 3 percent for each additional degree. The ETUI report adds that in certain sectors, output begins falling as early as 16 degrees, declining by 2 percent per degree. During extreme heat waves in Southern Europe, losses have reached 25 percent.
Summit in Vienna debates structural changes
On Wednesday, politicians, climatologists, health scientists, building managers, and union representatives gathered at Austria’s education ministry in Vienna for a summit on stricter heat protection rules. The discussions focused on shading buildings, enshrining regulations for extremely hot days into law, and potentially moving summer holidays earlier in the year.
Austria’s national parliament has already acted on a separate measure, approving the introduction of a "BauID" card for roughly 138,500 construction workers. Issued by the construction workers’ vacation and severance fund, the card is designed to enable real-time inspections.
Employer obligations and tricky clothing rules
German workplace regulations already set clear thresholds. The Technical Rules for Workplaces (ASR A3.5) recommend easing measures from 26 degrees Celsius, and mandate specific actions once the thermometer hits 30 degrees. Yet only about half of German offices have air conditioning; in private households the figure is one in five.
Meeting your legal obligations under workplace regulations — whether for temperature thresholds or general safety — requires proper documentation and training materials. A free Health & Safety Toolkit gives UK businesses ready-to-use risk assessments, toolbox talks, and checklists that cover key legislation from the Health & Safety at Work Act to COSHH. Used by over 37,000 UK companies, it helps you demonstrate compliance and protect your workforce. Download the free Health & Safety Toolkit
Clothing policies remain a flashpoint. In May 2024, the Düsseldorf Regional Labor Court upheld the dismissal of an employee who refused to wear prescribed workwear despite the heat – provided that safety or corporate identity considerations take precedence. Generally, works councils have a co-determination right when it comes to dress codes. Some companies are going further: a roofing firm in Melk, Lower Austria, struck a new protective agreement for its workers just this week.
Heat dome forecast for late July
Meteorologists are predicting a so-called heat dome for the second half of July. Eastern Austria in particular could see temperatures climb to 35 degrees Celsius. Doctors are warning of severe strain on the circulatory system and urging people to drink plenty of fluids.
