ISO 14001
Environmental management systems — Requirements with guidance for use. Updated: September 29, 2026.
ISO 14001 certifies an environmental management system. It is included here because it increasingly turns up in the same supplier questionnaires as ISO 27001 and ISO 9001, and because IT organisations that assume it is only for manufacturers are usually wrong about their own footprint.
What It Requires
- Identify your environmental aspects — the ways your activities interact with the environment — and which of them are significant.
- Know your legal obligations, which for IT commonly means waste electrical equipment regulations and how hardware is disposed of.
- Set objectives and measure against them, rather than stating intentions.
- Control your operations so the significant aspects are actually managed.
- Plan for environmental emergencies, which for a data centre includes things like coolant or fuel release.
- Consider the life cycle, including what you buy and what happens to it at the end.
What It Means for an IT Organisation
The aspects that matter are usually these: energy consumption, which for infrastructure is the dominant one and is measurable; hardware disposal, which carries both an environmental and a data-security obligation and where a certificate of secure destruction serves both; procurement choices, including provider energy sourcing; and travel.
There is a genuine overlap with ordinary good infrastructure practice worth pointing out. The infrastructure audit finding that a third of your virtual machines are barely used is simultaneously a cost finding and an energy finding, and right-sizing reduces both. The same is true of switching off non-production environments outside working hours. That makes 14001 unusually cheap to evidence for an organisation that already manages capacity properly.
Who Needs It
Suppliers to large corporates and to the public sector, where environmental criteria are routinely scored; organisations with reporting obligations of their own; and any business whose customers ask about supply-chain sustainability. For a small consultancy it is often disproportionate — but the measurements it asks for are worth having regardless.
What the Auditor Will Ask to See
- The register of environmental aspects, with the reasoning for which are significant. For an IT organisation energy and hardware disposal usually dominate.
- The legal register and evidence of compliance — for IT, most often the waste electrical equipment rules.
- Energy consumption measured, not estimated, with a trend. If you cannot measure your own racks, the provider's figures and your own utilisation data stand in.
- Objectives with numbers, and progress against them.
- Hardware disposal: certificates of recycling and of secure destruction, which satisfy this standard and the information security one at the same time.
- Procurement criteria showing environmental factors were weighed.
- Emergency preparedness for the environmental incidents that apply to you — coolant, fuel, battery.
Worth knowing: the infrastructure audit finding that a third of your virtual machines are barely used is simultaneously a cost finding and an energy finding, and right-sizing evidences both. The same is true of switching non-production environments off outside working hours. For an organisation already managing capacity properly, much of this evidence exists before the project starts.
What It Does Not Prove
That your environmental impact is low. It certifies that you have identified your significant impacts, set objectives, measured against them and improved — starting from wherever you started. An organisation with a large footprint managing it deliberately is conformant; one with a small footprint and no system is not.
So as a supplier question it says a process exists, not that the number is good. If the number is what you care about, ask for the measurements rather than the certificate — and under this standard they should exist.
Getting Certified
The same management system structure and the same three-year cycle. If you already hold ISO 9001 or ISO 27001, the shared clauses mean this is one of the cheapest additional certifications to obtain.
