ISO 14001:2026 is the fourth edition of the international standard for environmental management systems, published by ISO on 15 April 2026. It sets out what an organisation of any size must do to control its environmental aspects, meet its compliance obligations and keep improving its environmental performance. It replaces ISO 14001:2015 and its 2024 climate amendment. It is voluntary, and certification bodies, not ISO, issue certificates.
Last year I sat with the owner of a family bakery group in KwaZulu-Natal. A national retailer’s supplier portal had asked her a yes or no question: does your business hold ISO 14001? She had a food safety certificate on the wall, a diesel boiler behind the bakery and no idea what the question meant. This guide is the conversation we had, written down.
Want the whole standard in plain words before anyone asks you about it? Introduction to ISO 14001:2026 walks every clause on South African food sites, and you finish able to name the significant aspects of your own job, the controls that go with them and what to do in an environmental emergency. About 6 hours online, R1 495.
What are the key facts about ISO 14001:2026?
ISO 14001:2026 is a requirements standard: it says what an environmental management system must do, not how your site must look. It applies to any organisation in any sector, and it is the edition every certificate will move to as the transition runs its course.

What does an environmental management system actually do?
An environmental management system (EMS) is the set of linked processes a site uses to find out how it affects the environment, decide what matters most, control it and check that the controls work. ISO 14001 names three intended outcomes: better environmental performance, meeting compliance obligations and achieving environmental objectives.
On almost every food site I have audited, the environmental work already existed in pieces. Maintenance serviced the boiler. Stores signed for the hazardous waste. The engineer kept the effluent results in a drawer. Nobody had joined the pieces up.
That is the job of the EMS. It starts with your environmental aspects, the parts of your activities that interact with the environment, such as effluent leaving the CIP system or smoke leaving the boiler stack. Each aspect has an impact, the change it causes, such as a pH shock to the municipal sewer works or fine particles in the air your neighbours breathe. We go deeper on this in environmental aspects and impacts, with South African examples.
Once you know your aspects, the system makes you decide which are significant, link them to the law, set controls and objectives, train people, check results and fix what goes wrong. That loop is Plan, Do, Check, Act.

What do clauses 4 to 10 require, in plain words?
Clauses 4 to 10 run in order from understanding your situation to improving the system. Clauses 1 to 3 set out the scope, references and terms. The requirements an auditor checks against start at clause 4.
| Clause | In plain words | What it looks like on site |
|---|---|---|
| 4 Context of the organization | Know the issues that affect your system, including environmental conditions such as pollution levels, water availability and climate change. Know who has a stake and what they expect. Set the scope | Municipal water restrictions in a drought, neighbours along the stream, a retailer’s supplier questionnaire |
| 5 Leadership | Top management is accountable. A policy commits to protecting the environment, preventing pollution, meeting compliance obligations and improving. Roles are assigned | The managing director signs the policy and receives a monthly environmental report |
| 6 Planning | Aspects and impacts, compliance obligations, risks and opportunities, objectives and the plans to reach them, and planning of changes | Effluent pH, boiler emissions, ammonia, packaging waste. An objective to cut water used per tonne of product |
| 7 Support | Resources, competence, awareness, communication and documented information | A CIP operator trained in spill response. A toolbox talk on the new waste bins |
| 8 Operation | Operating criteria and controls, control of externally provided processes, a life cycle view, and emergency preparedness and response | A bunded chemical store, checks on the waste contractor’s licence, a diesel spill drill |
| 9 Performance evaluation | Monitoring and measurement, evaluation of compliance, internal audit and management review | Monthly effluent results against permit limits, a documented audit programme |
| 10 Improvement | Continual improvement, and nonconformity with corrective action | An overflowing grease trap traced to its cause and the fix checked a month later |
If you also run FSSC 22000, ISO 22000 or ISO 9001, you will recognise the shape. All three use the same clause frame, so a lot of your existing system can be shared. I cover that in ISO 14001 vs ISO 9001 vs ISO 22000.
What changed from ISO 14001:2015?
Less than many people feared. The 2026 edition adopts ISO’s harmonized structure, moves risks and opportunities into a new sub-clause 6.1.4, adds clause 6.3 on planning of changes, replaces outsourced processes with externally provided processes, products or services, and asks for audit objectives and a documented audit programme.
The changes that will reach your site in practice:
- 4.1 context. Issues must include environmental conditions, with pollution levels, natural resources, climate change, biodiversity and ecosystem health as examples.
- 6.1 planning. Now five sub-clauses: general, aspects, compliance obligations, risks and opportunities, and planning action. If your procedures say “6.1.4 planning action”, the number has moved to 6.1.5.
- 6.1.2 aspects. Normal, abnormal and potential emergency conditions are spelt out, with a note on the life cycle perspective.
- 6.3 planning of changes. New. Changes that affect the EMS must be carried out in a planned way so the system still delivers.
- 8.1 operation. Externally provided processes, products or services relevant to the EMS must be controlled or influenced, with the type and extent defined.
- 9.2.2 audit programme. Each audit needs defined objectives, criteria and scope, and the programme itself must be available as documented information.
- 9.3 and clause 10. Management review is split into general, inputs and results. Clause 10 now has two sub-clauses.
There is still no stand-alone climate clause, no requirement for a full life cycle assessment and no preventive action clause. The full list, with what each change means for your evidence, is in ISO 14001:2026 vs 2015: every change.
If your site already holds a 2015 certificate, the move to the new edition is a project with a deadline. Certification bodies expect it to end about 30 April 2029, but confirm the dates with your own certification body. Transition to ISO 14001:2026 (about 8 hours, R1 950) gives you a delta check of your own system, an evidence position on every change and a dated action plan.
Supervisors and QA staff do not need the delta check. They need to understand the system they work in. Start Introduction to ISO 14001:2026 today: 21 short lessons, about 6 hours on your phone, scenario checks marked the moment you submit, R1 495.
Is ISO 14001 a legal requirement in South Africa?
No. ISO 14001 is a voluntary standard. The law that applies to your site applies whether you are certified or not. ISO 14001 adds a system that makes sure you know those obligations and meet them.
The Acts behind most food and agricultural sites are the National Environmental Management Act 107 of 1998 (NEMA), the National Environmental Management: Waste Act 59 of 2008, the National Environmental Management: Air Quality Act 39 of 2004, the National Water Act 36 of 1998 and your municipality’s by-laws on trade effluent, air quality and waste. NEMA section 28 places a duty of care on anyone who causes, or may cause, significant pollution or degradation of the environment. That duty does not wait for a certificate.
ISO 14001 calls these legal requirements, plus anything else you choose to comply with such as a retailer’s code, your compliance obligations. Clause 6.1.3 asks you to determine them, work out how they apply and take them into account. Clause 9.1.2 asks you to evaluate whether you are meeting them. For an overview of each Act and where it touches a food site, read the South African environmental laws behind ISO 14001.
Where should a South African business start?
Start by understanding why you are being asked, then train the people who will carry the system, then walk the site with fresh eyes. Buying a template manual on day one is the most expensive way to start.
- Find out who is asking and why. A retailer, an export buyer and a certification body each want different evidence.
- Buy your own copy of ISO 14001:2026. Everything else in your system will refer to it.
- Train the people who will carry it. Supervisors, QA and SHEQ staff. They will find aspects you would miss.
- Walk the site. List every activity and what it uses, releases, discharges or throws away, under normal running, start-up, shutdown and breakdown.
- Collect what you already hold. Permits, licences, the trade effluent permit and waste safe disposal certificates.
- Run a gap assessment and write a dated plan. The full method is in how to implement ISO 14001:2026.
- Talk to certification bodies once internal audit and management review have run at least once.
The person leading the build needs more than an introduction. ISO 14001:2026 Understanding and Implementation (about 24 hours, R4 800) takes you through building your own registers, emergency plan, monitoring plan, audit programme and management review pack. The people around that person need the foundation first. You can see all four courses on the ASC ISO 14001 training page.
Frequently asked questions
What is ISO 14001:2026?
ISO 14001:2026 is the fourth edition of the international standard for environmental management systems, published by ISO in April 2026. It replaces ISO 14001:2015 and its 2024 amendment in a single text.
Is ISO 14001 compulsory in South Africa?
No, it is voluntary. Customers may ask for it, and South Africa’s environmental Acts and municipal by-laws apply to your site whether or not you hold a certificate.
Is an ISO 14001:2015 certificate still valid?
Yes, during the transition period. Certification bodies expect about three years ending about 30 April 2029, so confirm the exact dates with your own certification body.
Can a small business use ISO 14001?
Yes. The standard applies to any organisation of any size, and the amount of documented information can match the size and complexity of the site.
