Identifying and Evaluating Environmental Aspects Under ISO 14001
ISO 14001 Clause 6.1.2
This clause requires the organisation to determine the environmental aspects related to its activities, products and services that it can control and influence, and their environmental impacts, within a lifecycle perspective.
ISO 14001 Clause 6.1.2 - Environmental Aspects
ISO 14001:2026 Clause 6.1.2 is arguably the most important clause in the entire standard. It is where the organisation identifies what its activities, products and services do to the environment, decides which of those interactions matter most, and creates the foundation that drives objectives, operational controls, monitoring, training and emergency preparedness.
An environmental aspect is an element of the organisation's activities, products or services that interacts or can interact with the environment. The change to the environment that results - good or bad - is the environmental impact. Aspects and impacts are linked by cause and effect. Energy use is an aspect; the resulting greenhouse gas emissions are the impact. Waste oil generation is an aspect; potential soil and water contamination is the impact.
What Has Changed in ISO 14001:2026
The 2026 edition has clarified what an organisation must take into account when determining its environmental aspects. Under ISO 14001:2026, the organisation must consider:
- normal and abnormal conditions;
- change, including planned or new developments, and new or modified activities, products and services;
- potential emergency situations.
The explicit reference to abnormal conditions is the change. Abnormal conditions are situations that are not typical, happen rarely or are unplanned - things like start-up and shut-down phases, plant trips, adverse weather affecting operations, or extended runs at peak capacity. These can introduce new aspects or change existing ones, often increasing the environmental impact during the period the abnormal condition lasts.
Most organisations were already considering some abnormal conditions implicitly. The 2026 wording makes it explicit so that an auditor can clearly see the consideration has happened, and so that operational controls and emergency preparedness can be designed for the full range of conditions the organisation encounters.
Determining Aspects with a Life Cycle Perspective
The standard requires the organisation to consider environmental aspects with a life cycle perspective. This does not mean a full life cycle assessment - that is a specialist exercise. It means thinking about the stages of a product or service from raw material extraction through to end-of-life disposal, and identifying aspects at each stage that the organisation can control or influence.
The stages typically include:
- acquisition of raw materials, including extraction;
- design and development;
- operational or manufacturing processes;
- transportation and delivery;
- use of the product or delivery of the service;
- end-of-life treatment and final disposal.
An organisation that only buys finished components has very limited influence at the raw materials extraction stage. An organisation that designs its own products has a great deal of influence at every stage. The standard expects the organisation to be honest about which stages it can affect and to focus its effort accordingly.
Determining Significance
Once aspects have been identified, the organisation determines which are significant. The standard does not prescribe a method - the organisation sets its own significance criteria. Common criteria include the scale of the impact, its severity, its duration, the frequency with which it occurs, the regulatory status of the activity, and the level of stakeholder concern.
Three checks work well in practice. First, could the aspect lead to an emergency situation? Second, could it have a significant impact on the environment? Third, is there current legislation covering the impact? An aspect for which any of those three are yes is likely to be significant.
Significant aspects drive the rest of the system. They become priority candidates for environmental objectives at Clause 6.2, they need operational controls at Clause 8.1, they often require training and competence at Clause 7.2, and they need monitoring at Clause 9.1.
Get the aspects register right and the rest of the system flows from it. Get it wrong and you will be patching gaps for years.
The biggest single mistake I see is making the register too short. Organisations think they need to keep it tidy, so they consolidate everything into half a dozen broad categories. Then when an auditor asks how a specific issue - say, refrigerant gas leaks - is being managed, it is not in the register and there is no clear control. Be granular enough to be useful.
For 2026 the change I will be looking at most closely is whether abnormal conditions have been considered. If your aspects register only reflects how the place runs on a normal Tuesday, you are missing potentially significant aspects. What happens at start-up, what happens at shut-down, what happens when the production line trips, what happens when there is unusually heavy rain on site. These are the conditions where environmental incidents tend to occur.
On our site we update the aspects register whenever we make a process change, not just at management review. New chemical, new piece of plant, new product line - the question we ask is what is the environmental aspect, what is the impact, and is anything different from what we already have controls for.
It catches things you would otherwise miss until they become a problem.
Aspects and impacts is just two questions. What does the business do that touches the environment, and what happens as a result. Write it down. Decide which of those things matter most. Then go fix the ones that matter most. The standard wraps it in language but that is what it is.
Practical Compliance Guidance
Environmental aspects and impacts are recorded in a dedicated register. The IMS1 Manual sets out the procedure for identifying aspects in Section 6.2 Environmental Assessment, including the significance criteria the organisation applies.
