Overview
ISO 45001:2018/Amd 1:2024 is the first amendment to ISO 45001:2018 and introduces targeted climate action changes to occupational health and safety (OH&S) management systems. Prepared by ISO/TC 283, this amendment requires organizations to determine whether climate change is a relevant issue within their management system context and highlights that interested parties may have climate-related requirements.
This short amendment aligns OH&S management with emerging expectations for climate-aware organizational management and helps organizations integrate climate considerations into existing ISO 45001 processes.
Key Topics
- Relevance of climate change: Organizations shall determine whether climate change is a relevant issue when establishing the context of the OH&S management system (addition to clause 4.1).
- Interested parties: A new note clarifies that relevant interested parties can have requirements related to climate change (addition to clause 4.2).
- Scope for integration: The amendment prompts integration of climate-related considerations into risk assessment, objectives and controls where relevant, without prescribing specific technical measures.
Keywords: ISO 45001, amendment, climate action, occupational health and safety, OH&S, climate change, interested parties, risk assessment, management systems.
Applications
This amendment has practical value across sectors where organizations operate OH&S management systems and face climate-related change or stakeholder expectations. Typical applications include:
- Integrating climate risk considerations into hazard identification and risk assessment workflows.
- Updating the organization-context analysis to record climate relevance and related implications for OH&S performance.
- Reviewing interested-party analyses and contractual or regulatory requirements that reference climate impacts, resilience or adaptation.
- Aligning OH&S objectives and controls with broader corporate climate policies or sustainability strategies.
Benefits for organizations:
- Improved resilience by explicitly considering climate-related hazards that may affect worker safety and health.
- Stronger stakeholder alignment by recognising and addressing climate-related requirements from regulators, customers or communities.
- Easier integration with other management systems (e.g., environmental or business continuity) where climate change is already considered.
Related Standards
- ISO 45001:2018 - Occupational health and safety management systems - Requirements with guidance for use (base standard).
- Other ISO standards on environmental and risk management may be relevant when integrating climate considerations (for example, ISO 14001 and ISO 31000), although specific cross-references should be checked against each organization’s implementation.
For implementation guidance or country-specific interpretation, consult your national standards body or the full ISO amendment text. The amendment is limited in scope and intended to ensure that climate change is considered where relevant within existing OH&S systems, without prescribing sector-specific technical solutions.
