Protecting Workers from Heat Risks: The European Union's Multifaceted Approach

The European Union is taking significant steps to safeguard workers from the occupational risks posed by extreme heat, a growing concern exacerbated by climate change.

The EU's Strategic Framework on Health and Safety at Work (2021–2027) prioritises addressing climate-related health risks, such as heat stress, as part of its broader agenda [1]. This framework forms the backbone of the EU's efforts to protect workers from heat-related hazards.

In response, the European Commission is currently reviewing the EU Workplace Directive 89/654/EEC with a focus on heat at work. This review follows the publication of heat-at-work guidance by EU-OSHA in May 2023 [1]. Advisory bodies like the Advisory Committee on Safety and Health at Work and the Senior Labour Inspectors’ Committee (SLIC) have also advanced recommendations and formed working groups to promote consistent enforcement of occupational safety directives concerning extreme temperatures [1].

A proposed directive under discussion outlines adaptation mechanisms to reduce workers’ vulnerability to extreme heat. This directive calls for the establishment of maximum allowable working temperatures, accounting for different sectors and individual circumstances [2]. It aligns with broader European concerns about outdoor workers’ exposure to heat and its physical and mental health consequences.

At the national level, countries like Luxembourg are updating occupational disease frameworks to include heat-related conditions based on scientific evidence linking prolonged thermal stress to kidney disease and other illnesses [3]. This reflects a wider European trend to modernize occupational health policies considering climate change effects.

The International Labour Organization (ILO) has highlighted the urgency of the situation, with millions of workers globally, including in Europe, facing extreme heat risks causing injuries and fatalities annually [4][5]. The ILO warns that 130 million workers in Europe are exposed to excessive heat, underscoring the need for protective regulations.

Key aspects of the proposed directive include establishing maximum working temperatures, mandatory heat risk assessments, and heat management plans. These measures aim to ensure workers' health and safety in the face of escalating heat risks, as foresight studies suggest that these risks will continue to escalate [2].

The European Trade Union Confederation (ETUC) has been at the forefront of advocating for greater protection from extreme heat. On 4 March, the ETUC adopted a resolution outlining a future directive aimed at preventing occupational heat risk [2]. This resolution aligns with the logic of the Framework Directive on occupational health and safety by advocating the STOP approach [2].

Regulation must address both common and differentiated needs created by excessive heat. The Mediterranean region, for example, is expected to experience significant temperature increases, making efforts to address extreme heat risks increasingly complex [2]. The resolution advocates for the use of Wet Bulb Globe Temperature (WBGT) in risk assessments, ensuring inclusivity for vulnerable groups [2].

In some countries, such as Spain and Greece, regulations requiring companies to communicate alerts issued by meteorological authorities are already in place [2]. Greece has temporarily approved the suspension of outdoor work during periods of extreme temperatures [2].

The ILO's latest report, "Ensuring Safety and Health at Work in a Changing Climate," highlights this critical issue [4]. The report underscores the need for a coordinated, multi-faceted approach to protect workers from heat risks associated with climate change.

In summary, the EU’s approach combines legislative review, expert advice, enforcement coordination, and adaptation tools aimed at protecting workers from heat risks associated with climate change [1][2][3][4][5]. This approach reflects a growing recognition of the urgent need to address heat-related occupational risks and the potential for eco-anxiety, an emerging occupational safety and health risk, to exacerbate these risks.

1. To counter the escalating heat risks due to climate change, the European Union is prioritizing the integration of environmental-science, specifically climate-change research, into its Health-and-Wellness agenda.
2. As part of this comprehensive strategy, the EU is having discussions on a proposed directive that shines light on workplace-wellness, mandating maximum temperature limits, heat risk assessments, and heat management plans.
3. The ILO's report, "Ensuring Safety and Health at Work in a Changing Climate," supports this multifaceted approach, underlining the importance of health and safety considerations in response to the challenges posed by environmental changes and climate-related health risks.
