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.

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.

Written from an infrastructure perspective. We are not a certification body, an audit firm or a legal adviser, and this is not legal advice. Standards are revised on a cycle — confirm the current edition before you commit.
