Planning and managing of changes (NEW clause)

What changed in the 2026 revision

Entirely new clause in 2026. Requires a structured, documented approach to plan and manage changes that could affect EMS outcomes. Changes can originate from internal or external sources. Must clearly distinguish emergency situations from abnormal operations. Certification-body analysis: 'This formalization addresses a long standing gap where change management has been inconsistently applied.'

What auditors will look for

Implement a documented Management of Change procedure. This is a NEW requirement — most 2015-era systems will not have this. The procedure should cover: (1) identifying the need for change; (2) assessing potential impacts on EMS outcomes; (3) planning the change with resources and timelines; (4) implementing and verifying.

How to close the gap

  1. 1Create a Change Request Form (who, what, why, when, environmental impact)
  2. 2Define an environmental impact assessment checklist for proposed changes
  3. 3Assign responsibility for change approval (typically senior manager)
  4. 4Create a change log to track all assessed changes
  5. 5Link the MoC process to your risk register and aspects register
  6. 6Test the process with a recent real change as a pilot
  7. 7Brief all relevant staff on when and how to raise a change request
