Operational control under ISO 14001 (clause 8.1)

Operational control means that you plan the work that has an environmental impact and keep it under control. Clause 8.1 of ISO 14001  requires criteria for those processes, and controls that match them. You record that the work is carried out as planned. It is the bridge between your environmental aspects and the daily work on the shop floor. For more on the standard as a whole, see the requirements of ISO 14001.

What does clause 8.1 specifically require?

The standard asks for three things. You plan, carry out and control the processes needed for the environmental management system. You set criteria for those processes. And you apply the control in line with those criteria, with enough documented information to give confidence that the work is done as planned.

You also carry out the actions that come from your planning in clause 6. Think of the measures that follow from your environmental aspects. You control planned changes, and for unintended changes you assess the consequences. You keep outsourced processes under control or influence them. You pass on the relevant environmental requirements to external providers, such as contractors, hauliers and cleaners.

Why an auditor looks at this

Clause 8 is where the system has to prove on the shop floor that it works. An auditor walks through the processes and asks: what happens here, what is the criterion, and how do you know it is going well? If that answer is missing, a nonconformity often follows.

This is also the area where the limit of “documenting enough” is often misunderstood. The standard does not require every process to be described in detail. It requires documentation to the extent that it gives you confidence that the process works as planned.

An example: waste separation on the construction site

A contractor (fictional, 35 employees) has an environmental aspect: construction waste is often not separated properly. The company therefore sets up operational control for that process. The table shows what this can look like.

Note how the example is built. The process has a criterion you can measure. The check and the record are documented, so an auditor can verify them. And there is a plan for when things go wrong. This is how operational control works in practice.

What belongs in your controls?

Not every process needs the same level of detail. Start with the processes that carry the most weight in your environmental aspects register. These are the processes with a significant aspect.

External suppliers and the value chain

Clause 8.1 is not only about your own work. If an external party causes environmental risks on your behalf, you must keep those under control or influence them. That means passing on the relevant requirements to that party and recording the agreements.

In practice, for the contractor in the example, this means the waste processor needs to know which streams are delivered and how they must be separated. The crane hire company needs to know which oil it may use. This is set out in purchase terms, a work agreement or a toolbox talk list.

The life cycle also plays a role here. You do not need to carry out a full life cycle analysis. You do look at the stages of a product or service that you can influence, such as design, purchasing, transport, use and disposal. For this, read the life cycle perspective.

Common mistakes

• A criterion nobody can measure. “As little waste as possible” is not a criterion. “Less than 10% mixed waste per container” is.
• A control without a record. If you carry out the check but write nothing down, you cannot prove it.
• Treating all processes the same. An office process with low environmental risk does not need the same level of detail as a paint spray booth.
• Forgetting that external parties count. If a subcontractor produces waste on your construction site, you must control or influence that waste stream.
• A work instruction that nobody knows. An instruction in a folder is not control. The employee must know it and use it.

How does this fit with the rest of the system?

Operational control links to your environmental objectives. If one objective is to produce less waste, the control measures on the waste processes are the means to achieve it. Read more about this in environmental objectives (6.2).

Emergency situations also fall under clause 8. There you prepare for incidents that you do not see every day. The routine of operational control is the normal work, and the emergency situation is the exception.

Common questions

How many criteria do I need per process? As few as needed. A process with one clear criterion is better than ten vague criteria that nobody checks.

Do I have to describe every process in full? No. Document what is needed to have confidence that the process works as planned. For the rest, a short instruction is enough.

What if a supplier cannot meet an environmental requirement? Record which requirement applied, what the supplier replied and which measure you took. This could be a different supplier or an adjusted agreement.

Next step

Start with one significant process from your register and work it out in full using the table above. Then apply the same format to the other processes. For a complete overview of what the auditor checks, use the ISO 14001 checklist.
