ISO 14001:2026 for Auditors > Clause 6.3
Explained: Planning of Changes
Clause 6.3 of ISO 14001 asks an organisation to plan changes that may affect its Environmental Management System. In plain English, this means thinking through environmental risks, opportunities, controls and responsibilities before making changes that could affect EMS performance.
What is ISO 14001 Clause 6.3 trying to achieve?
Clause 6.3 is about avoiding accidental damage to the EMS when the organisation changes.
Organisations change all the time. They introduce new processes, new equipment, new materials, new suppliers, new working patterns and new services. Some changes are planned carefully. Others happen quickly and informally.
Clause 6.3 expects the organisation to plan changes that could affect the EMS so that environmental impacts, compliance obligations, risks and controls are considered before the change is made.
The aim is simple: change should not accidentally create environmental problems, compliance failures or weakened controls.
Why planning changes matters in an EMS
Many environmental problems happen because something changed and nobody considered the environmental consequences.
For example:
- a new chemical is introduced without reviewing storage, spill response or waste disposal requirements;
- a new supplier is appointed without checking environmental controls or compliance expectations;
- a production line is moved and drainage risks are not reconsidered;
- a site layout changes and emergency access or spill response equipment becomes harder to reach;
- new packaging is introduced and waste streams increase;
- staffing changes leave key EMS responsibilities unclear;
- a contractor begins work without suitable environmental induction.
Clause 6.3 helps the organisation build environmental thinking into change decisions before issues appear.
What types of changes may need planning?
Clause 6.3 can apply to many different types of change. The key question is not simply whether something is “big”, but whether the change could affect the EMS, environmental performance, compliance obligations, operational controls, risks, opportunities or the organisation’s ability to achieve intended outcomes.
Changes that may need planning include:
- new or changed activities, products or services;
- new or modified processes, production methods or service delivery arrangements;
- changes to equipment, plant, machinery, tools or environmental control equipment;
- changes to facilities, buildings, site layout, storage areas, drainage arrangements or physical boundaries;
- new materials, chemicals, substances, packaging or process inputs;
- changes to the technical specifications of materials, products, components or process inputs;
- changes to suppliers, contractors, outsourced processes or externally provided services;
- changes to transport, logistics, distribution, delivery routes or storage arrangements;
- changes to waste streams, waste contractors, waste storage arrangements or disposal routes;
- changes to compliance obligations, including legal, permit, licence, customer, contractual or voluntary requirements;
- changes in the needs and expectations of interested parties;
- changes in environmental aspects, impacts, risks or opportunities;
- changes in environmental objectives, targets, action plans or performance indicators;
- changes to operational controls, procedures, work instructions or inspection routines;
- changes to emergency preparedness and response arrangements;
- changes in roles, responsibilities, authorities, staffing levels or organisational structure;
- changes in competence needs, training arrangements or awareness requirements;
- changes in monitoring, measurement, analysis or evaluation methods;
- changes in documented information, records, software systems or data-management arrangements;
- changes in technology, automation, digital systems, technical knowledge or best available methods;
- changes to business assets, ownership, mergers, acquisitions, joint ventures, divestitures or organisational restructuring;
- changes caused by supply chain disruption, labour disputes, loss of key suppliers or contractor availability;
- changes caused by external disruption such as severe weather, natural disasters, political unrest, conflict, infrastructure failure or market disruption;
- temporary changes, trials, pilot projects, short-term workarounds or emergency arrangements;
- unplanned or unintended changes that have already occurred and may need review or mitigation.
Not every change needs a lengthy formal change-control process. However, the organisation should be able to show that changes with environmental significance are considered before implementation where possible, and reviewed afterwards where unintended changes occur.
Auditor tip
When auditing Clause 6.3, do not only ask whether the organisation has a “change procedure”. Pick a recent change and follow the trail. Was the environmental impact considered? Were compliance obligations checked? Were controls, competence, communication and documented information updated where needed?
What does ISO 14001 expect?
ISO 14001 expects the organisation to ensure that changes relevant to the EMS are carried out in a planned manner.
In practical terms, the organisation should consider:
- what is changing;
- why the change is happening;
- which environmental aspects and impacts could be affected;
- whether compliance obligations could change;
- whether new risks or opportunities are created;
- whether operational controls need to change;
- whether competence, awareness or communication is needed;
- whether documented information needs updating;
- who is responsible for implementing and reviewing the change;
- how the organisation will check whether the change has been effective.
The standard does not require unnecessary bureaucracy. It requires sensible control of change where change could affect the EMS.
Planning changes and environmental aspects
Planned changes should trigger a review of environmental aspects and impacts where relevant.
For example:
- a new cleaning chemical may create new storage, use, disposal or spill-response aspects;
- a new production process may change energy use, emissions, waste or noise;
- a new delivery model may affect fuel use and transport emissions;
- new packaging may affect resource use and waste disposal;
- a new contractor activity may introduce new pollution risks.
Auditors should check whether changes are reflected in the aspect and impact register where appropriate.
Planning changes and compliance obligations
Changes can affect legal and other requirements.
The organisation should consider whether a planned change creates, removes or alters compliance obligations.
Examples include:
- new equipment requiring permits, inspections or maintenance controls;
- new waste streams requiring different classification or disposal routes;
- new chemicals requiring updated safety, storage or disposal arrangements;
- new customer requirements for environmental reporting;
- changes to operations affecting planning conditions or permits;
- new contractors needing environmental competence checks;
- site expansion affecting drainage or emissions requirements.
Compliance obligations should not be reviewed only after problems occur. They should be considered as part of planning.
Planning changes and risks and opportunities
Changes can create both risks and opportunities.
Risks may include:
- increased emissions;
- increased waste;
- loss of existing controls;
- new emergency scenarios;
- compliance gaps;
- lack of competence;
- contractor control weaknesses;
- inadequate monitoring;
- confusion over responsibilities.
Opportunities may include:
- lower energy use;
- reduced waste;
- better resource efficiency;
- cleaner technology;
- improved supplier performance;
- improved data collection;
- better emergency preparedness;
- stronger environmental performance.
A planned change should not only ask “what could go wrong?” It should also ask “what could be improved?”
Planning changes and operational control
If a change affects an operational process, the organisation should consider whether operational controls need to be created, updated or removed.
This may include:
- work instructions;
- inspection routines;
- maintenance plans;
- waste segregation arrangements;
- spill response procedures;
- contractor controls;
- emergency arrangements;
- monitoring points;
- documented information;
- training and awareness.
Simple example
If a site changes where chemicals are stored, the EMS may need updated storage controls, spill-kit locations, signage, inspection checklists, emergency response arrangements and staff briefings.
Planned versus unplanned change
Clause 6.3 is mainly about planned change, but auditors should also consider how the organisation deals with changes that happen quickly or unexpectedly.
Examples of less controlled change include:
- temporary storage arrangements;
- emergency supplier substitution;
- unexpected staff absence affecting EMS roles;
- urgent maintenance or repair work;
- short-term process changes;
- temporary contractor work;
- weather-related operational changes.
The EMS should be flexible enough to manage urgent changes without ignoring environmental risk.
Practical implementation guidance
Organisations can manage planning of changes through existing business processes. A separate EMS change process is not always necessary if environmental issues are built into current change controls.
Useful methods include:
- change request forms;
- project planning checklists;
- management of change procedures;
- procurement approval processes;
- new product or process introduction reviews;
- contractor approval processes;
- risk assessment reviews;
- aspect and impact review prompts;
- compliance obligation review prompts;
- pre-start environmental checks;
- management review action tracking.
A simple EMS change review may ask:
- Does this change affect environmental aspects or impacts?
- Does it affect compliance obligations?
- Does it create new risks or opportunities?
- Does it require new or changed controls?
- Does it affect competence, awareness or communication?
- Does documented information need updating?
- Who is responsible for the change?
- How will the change be reviewed after implementation?
What auditors typically look for
Auditors look for evidence that changes affecting the EMS are considered and controlled before implementation where practicable.
Evidence may include:
- change request records;
- project plans;
- risk assessments;
- updated aspect and impact registers;
- updated compliance obligation registers;
- updated procedures or work instructions;
- training or briefing records;
- contractor communication records;
- inspection or monitoring records;
- management review minutes;
- pre-start checks;
- post-change review records;
- corrective actions arising from change-related issues.
Auditor tip
Ask about a recent change. Then follow the evidence trail. Was the environmental impact considered before the change? Were obligations reviewed? Were controls updated? Were people briefed? Was the change reviewed after implementation?
Common weaknesses in Clause 6.3
- environmental review happens after the change instead of before it;
- change processes focus on cost, safety or production but ignore environmental issues;
- aspect registers not updated after changes;
- compliance obligations not reviewed when activities change;
- new contractors or suppliers introduced without environmental checks;
- documented information not updated;
- staff not briefed on changed environmental controls;
- temporary changes become permanent without review;
- emergency situations created by change are not considered;
- post-change effectiveness is not evaluated.
Weak example
“The organisation installed a new washdown area and updated the procedure afterwards.”
This is weak if drainage, wastewater controls, chemical use, spill risk, staff competence and compliance obligations were not considered before the change was made.
Better example
“Before installing the new washdown area, the organisation reviewed drainage routes, wastewater controls, chemical use, spill risk, permit requirements, staff competence and emergency response arrangements. Procedures and inspections were updated before use, and effectiveness was reviewed after the first month.”
This is stronger because the environmental effects of the change were considered before implementation and checked afterwards.
Real-world example: new chemical introduced
A manufacturing site introduces a new cleaning chemical.
Planning of the change should consider:
- environmental aspects and impacts of storage, use and disposal;
- spill response requirements;
- waste classification and disposal routes;
- storage compatibility;
- labelling and signage;
- staff competence and awareness;
- contractor or supplier information;
- updates to documented information;
- whether emergency arrangements need changing;
- whether compliance obligations are affected.
An auditor could test this by reviewing the change approval record, updated aspect register, training records, storage arrangements and waste documentation.
Real-world example: office relocation
An office-based organisation moves to a new building.
Planning of the change may consider:
- energy performance of the new building;
- waste and recycling arrangements;
- landlord environmental requirements;
- commuting and business travel impacts;
- IT equipment movement and disposal;
- procurement of new furniture or equipment;
- staff communication;
- changes to emergency arrangements;
- updates to EMS scope, context and aspects.
This shows that planning of changes applies to service and office environments as well as industrial operations.
