As climate change continues to reshape the global landscape, its implications for occupational health and safety (OH&S) are becoming increasingly significant. Organizations that are certified under ISO 45001: Occupational Health and Safety Management Systems must now consider climate-related risks as part of their strategic and operational planning. This integration is not only essential for compliance but also for ensuring long-term business resilience and sustainability.
Climate change introduces a range of environmental stressors that directly affect workplace conditions, employee well-being, and operational continuity. Key impacts include:
Rising global temperatures increase the risk of heat-related illnesses such as heat exhaustion and heat stroke, particularly in outdoor or high-temperature work environments.
Extreme heat and humidity can lead to the malfunction or accelerated degradation of machinery, posing safety hazards and increasing maintenance costs.
The frequency and severity of events such as floods, wildfires, droughts, and storms are escalating, disrupting operations and endangering personnel.
Climate change contributes to the spread of vector-borne and infectious diseases, especially in regions experiencing ecological shifts, thereby increasing occupational health risks.
ISO 45001 provides a robust framework for identifying and managing risks, including those arising from environmental changes. Several clauses are particularly relevant:
By embedding climate considerations into these foundational clauses, ISO 45001 enables organizations to proactively manage evolving safety challenges.
To effectively address climate-related OH&S risks, organizations should implement targeted operational controls:
These measures not only support ISO 45001 compliance but also enhance organizational agility and preparedness.
Incorporating climate change into OH&S risk management yields multiple strategic advantages:
Climate change is not just an environmental issue—it is a critical occupational health and safety concern. By leveraging the ISO 45001 framework, organizations can systematically identify, assess, and mitigate climate-related risks, ensuring safer workplaces and more sustainable operations. As global expectations around ESG performance and climate adaptation continue to rise, integrating these considerations into OH&S systems is not only prudent—it is essential.
