Identifying environmental aspects: how to inventory and assess them

What is the difference between an environmental aspect and an environmental impact?

An environmental aspect is something your organisation does, uses or produces that can affect the environment. The environmental impact is the result. Diesel consumption is the aspect; emissions and the contribution to climate change are the impact. Noting the two separately lets you tackle the cause later, not just the symptom.

An aspect always belongs to a concrete activity, product or service: a paint spray booth, a cooling system, a fuelling point, a loading dock. General themes such as sustainability are not aspects. Impacts can also be positive, such as solar panels on your roof, but in practice most attention goes to the negative ones.

How do you inventory environmental aspects step by step?

Start with your processes, not with a standard list. For each location, follow the process from arrival to departure: what comes in (raw materials, energy, water, substances), what happens to it and what goes out (products, waste, wastewater, emissions, noise, transport). Involve the people who do the work, because they know the abnormal situations.

Look at three situations: normal operation, deviations such as maintenance or a breakdown, and emergencies such as a leak or a fire. An aspect that is small in normal operation can become large during a breakdown. Also look at what you buy, outsource or deliver and can influence, because that chain belongs in your inventory too. These sources help you get started.

• Process descriptions and site plans
• Energy and water invoices, and waste receipts
• Permit, notification and inspection reports
• Substance register and safety data sheets
• Complaints from neighbours and earlier incidents
• A walk-through with supervisors and the maintenance team

How do you assess whether an aspect is significant?

Not every aspect needs the same attention. A significance assessment determines which aspects you actively control, measure or turn into an objective. A common method scores likelihood and severity, for instance from 1 to 5, and multiplies the two. You choose where the threshold lies and record it, for instance everything from 12 upwards.

Likelihood and severity do not tell the whole story. An aspect can also be significant because a legal requirement or permit condition applies to it, because neighbours or customers complain about it, or because you currently control it insufficiently. Define such criteria beforehand, so two assessors reach the same result for the same aspect.

Write down the reason for your judgement in one sentence per aspect, including the aspects you do not call significant. An auditor will want to know why an aspect is or is not significant, and in a year you will not remember either.

Example lines from an environmental aspects register

A register line contains the activity, the aspect, the impact, the situation, the score and the measure. Below are five example lines with a threshold of 12. The scores are illustrative: your outcome depends on your location, your sector and the scale you choose.

• Vehicle fleet: diesel consumption, impact emissions and climate change, normal situation. Likelihood 5, severity 3, score 15: significant.
• Refuelling and maintenance: leakage of oil or fuel, impact soil contamination, emergency situation. Likelihood 3, severity 5, score 15: significant.
• Construction and demolition: mixed waste, impact on resource use and processing capacity, normal situation. Likelihood 5, severity 2, score 10: below the threshold, but significant because a legal obligation applies.
• Grinding and drilling on site: noise, impact nuisance to neighbours. Likelihood 4, severity 2, score 8: below the threshold, but significant because of complaints.
• Office: paper use. Likelihood 2, severity 2, score 4: not significant, but worth monitoring.

From significant aspect to control measure

Attach at least one measure, an owner and a way to check that it works to every significant aspect. Think in order: can you prevent the aspect, otherwise reduce it, otherwise control it with procedures and resources? You rarely prevent diesel consumption, but you can lower it with driving instructions, route planning and, in time, more efficient or electric vehicles.

If an emergency is part of the aspect, such as a leak, write a scenario and practise it. Make measures measurable: an inspection round, a consumption overview or an objective with a deadline. Only then can you see after a year whether the register has really led to less environmental impact.

Common mistakes when identifying environmental aspects

A register filled just before the audit and never opened again adds little. It is also often too generic: a copied standard list rarely fits your processes. A good register is smaller and more specific, and everyone who works with it knows what it contains.

• Looking only at your own site and forgetting the chain
• Assessing only the normal situation, not breakdowns or emergencies
• Choosing a threshold without explaining why
• Significant aspects without a measure, owner or check
• Not feeding complaints and reports back into the register

When do you update the register?

An environmental aspects register is never finished. Update it when you get a new machine, substance, location or way of working, after a renovation, after an incident or complaint, and when a permit or regulation changes. Also schedule a fixed moment to go through the register, for instance annually, and include the outcome in the management review.

Your inspection rounds and reports are your earliest signal. If an inspector keeps finding the same deviation at the storage area, that aspect may need to score higher. The same goes for reports from neighbours or rising consumption. This keeps the register connected to what really happens on the shop floor.

How BrydgeOne supports this

In the Environmental aspects register, you record per aspect the theme, environmental impacts, activity, location, situation and life-cycle stage. Likelihood and severity from 1 to 5 give the significance score. An aspect also becomes significant when a compliance obligation applies, when it is not controlled or when complaints are known, and you always see the reason. Manual overrides require a justification.

An effects matrix shows aspects against impact categories, with significant aspects in red. AI can propose aspects based on your sector and processes, which you add or reject. You turn significant aspects that are insufficiently controlled into an improvement action or objective. Environmental inspections and Compliance obligations provide the evidence, and Objectives & KPIs tracks your progress.
