Updated ISO Standards

ISO 9001, ISO 14001 and ISO 45001 are being updated, bringing new requirements and expectations for certified organisations.

The latest edition of BS EN ISO 14001 was launched in April 2026. This 2026 update aligns with modern management system structures (including ongoing revisions to BS EN ISO 9001 and BS EN ISO 45001), making cross standard integration smoother than ever.

The 2026 update builds on and significantly strengthens expectations around climate change, risk-based thinking, lifecycle impacts, the sustainable use of natural resources and protection of biodiversity. The key changes include:

• clearer wording and improved practical guidance
• continued alignment with other ISO management system standards
• climate change fully embedded into EMS planning and context, requiring organisations to assess and act on climate-related risks and opportunities
• a requirement to actively integrate climate mitigation and adaptation into environmental planning, rather than treating climate as a standalone risk topic
• clearer linkage between EMS delivery and wider organisational climate strategy and governance
• clearer lifecycle thinking, with greater emphasis on upstream and downstream supply chain impacts
• greater expectations around sustainable procurement, supplier capability, material choices, and embodied carbon across the supply chain
• increased focus on natural resources and biodiversity impacts
• stronger leadership accountability and visibility
• clearer expectation that senior leadership can demonstrate ownership of environmental risk, performance and compliance outcomes
• clearer control of outsourced processes and subcontractors
• more explicit expectations around managing change and its environmental impacts
• stronger emphasis on performance monitoring, data-led decision making, and continual improvement
• a shift towards more structured, auditable environmental risk management, with clearer traceability between risks, controls and legal compliance obligations
• increasing expectation for robust, well-evidenced environmental management systems supported by structured (and increasingly digital) records rather than informal spreadsheets or ad hoc tracking tools

For construction organisations, the practical effect is a clear step-up in expectation across live projects. Climate considerations are no longer “add-ons” — they are embedded into how schemes are designed, planned and delivered. This means demonstrating how projects address climate resilience (flooding, overheating, extreme weather), reduce embodied carbon, and protect biodiversity from the earliest design stages through procurement and construction.

Supply chains also come into sharper focus. Clients will expect clearer evidence that subcontractors and suppliers are selected and managed based on environmental performance and not just on cost and programme. Material choices, sourcing decisions and procurement strategies will increasingly need to show lifecycle thinking and carbon awareness.

Finally, environmental management systems will need to be more robust, joined-up and evidence driven. The days of static registers and loosely linked documents are fading, replaced by more integrated, traceable systems that clearly show how risks are identified, controlled and verified in real time.

The transition period is up to three years from publication. Organisations certified to the 2015 edition will need to transition before April 2029 to maintain valid certification.

The revision of ISO 45001 is now approved and moving in to the planning stage. The reviewed version of the standard will not be published until 2027.
