# ISO 14001, the environmental management system

Markdown version of https://bluegreenmaterials.com/en/iso-14001. Updated on 2026-11-12.

ISO 14001 is the international standard with the requirements for an environmental management system: the way an organization identifies how it affects the environment, meets its obligations and improves its performance. The current edition is from 2026[^iso14001-2026]. Certification is optional, and it is not done by ISO but by a certification body[^iso14001-folleto].

## What an environmental management system is

It is the part of an organization's management system used to manage its environmental aspects, fulfil its compliance obligations and address its risks and opportunities. The standard expects three outcomes: better environmental performance, obligations fulfilled and environmental objectives achieved[^iso14001-2026].

It applies to any organization, of any size or sector, and covers the aspects of its activities, products and services that it can control or influence, with a life cycle perspective. It sets no performance figures: each organization sets its own. And it does not accept partial compliance: to claim conformity, all requirements must be met, without exclusions[^iso14001-2026].

- **670,000+**: certified organizations worldwide, according to the 2024 ISO Survey[^iso14001-noticia]
- **170+**: countries where it is used[^iso14001-folleto]
- **2026**: year of the fourth edition, published on 15 April[^iso14001-2026]

## The Plan, Do, Check, Act cycle

The standard rests on the PDCA cycle: a repeating process to achieve continual improvement, which applies to the whole system and to each of its parts[^iso14001-2026].

1. **Plan**: Set the environmental objectives and the processes needed to deliver results in line with the environmental policy.
2. **Do**: Implement the processes as planned.
3. **Check**: Monitor and measure the processes against the environmental policy, its commitments, objectives and operating criteria, and report the results.
4. **Act**: Take actions to continually improve.

## The requirements, clause by clause

**ISO 14001:2026, clauses 4 to 10[^iso14001-2026]**

| Clause | What it requires |
| --- | --- |
| 4. Context of the organization | Understanding the organization and its context, the needs of interested parties and the scope of the system |
| 5. Leadership | Top management commitment, an environmental policy and roles, responsibilities and authorities |
| 6. Planning | Environmental aspects, compliance obligations, risks and opportunities, environmental objectives and planning of changes |
| 7. Support | Resources, competence, awareness, internal and external communication, and documented information |
| 8. Operation | Operational planning and control, and emergency preparedness and response |
| 9. Performance evaluation | Monitoring, measurement, evaluation of compliance, internal audit and management review |
| 10. Improvement | Continual improvement, nonconformities and corrective action |

The 2026 edition does not rewrite the standard: it clarifies it and brings it closer to priorities such as climate change, biodiversity and resource efficiency, with more weight on leadership and on impacts across the value chain[^iso14001-noticia].

It shares its structure with other management system standards, such as ISO 9001 for quality and ISO 45001 for health and safety, so they can be integrated into a single system and the same audits[^iso14001-folleto].

## How a company gets certified in Mexico

The standard recognizes four ways to demonstrate conformity: declare it yourself, have it confirmed by a party with an interest in your organization, such as a customer, have an external party confirm your declaration, or certify your system with an external body[^iso14001-2026]. Certification is optional[^iso14001-folleto].

1. **Implement the full system**: All requirements, without exclusions, working and with their documented information[^iso14001-2026].
2. **Choose a certification body**: ISO does not certify or issue certificates: external bodies do. ISO recommends evaluating several and checking whether they are accredited[^iso14001-certificacion].
3. **Check its accreditation**: Accreditation is the formal recognition given by an independent body, known as an accreditation body[^iso14001-certificacion]. In Mexico, ema accredits certification bodies[^iso14001-ema].
4. **Audit and certification**: The body assesses your system and, if it conforms, issues the certificate: written assurance that it meets the requirements[^iso14001-certificacion].
5. **Name the edition**: ISO asks you to say "certified to ISO 14001:2026", not just "ISO 14001"[^iso14001-2026].

In Mexico, the 2015 edition was adopted as NMX-SAA-14001-IMNC-2015, identical to ISO 14001:2015[^iso14001-nmx]. If your certificate is to that edition, ISO asks you to consult your certification body on the transition[^iso14001-2015].

> **What it costs** There is no official price: each certification body quotes its own. That is why it pays to compare several before choosing[^iso14001-certificacion].

## ISO 14001 and PROFEPA's Clean Industry certificate

Mexico also has a government programme, which is not the same thing. The LGEEPA lets companies commit to voluntary environmental self-regulation and carry out voluntary environmental audits, and mandates a programme to promote them[^iso14001-lgeepa].

- **ISO 14001**: An international management system standard. It is certified by an external body; that body being accredited is advisable, not mandatory[^iso14001-certificacion].
- **National Environmental Audit Programme**: A PROFEPA programme. The audit examines the company's operations, the pollution and risk they generate and their compliance with regulations[^iso14001-lgeepa]. It grants Clean Industry (Industria Limpia), Environmental Quality or Tourism Environmental Quality certificates, depending on the sector, valid for two years[^iso14001-pnaa].

## Where scrap and waste fit

Under ISO 14001, what your operation generates, waste included, is analysed as an environmental aspect, and the laws that apply to you are compliance obligations. Both are identified in planning, controlled in operation and evaluated in performance[^iso14001-2026].

For waste, the reference law in Mexico is the LGPGIR[^lgpgir]:

- A **large generator** is anyone who generates 10 tonnes or more of waste per year[^lgpgir].
- **Management plan.** Large generators of special handling waste on the lists in the official standards must draw up and carry out a management plan, which is filed with the state authority[^lgpgir].
- **Hazardous waste.** Large generators register with SEMARNAT, keep a log and file an annual report; small generators also register and keep a log[^lgpgir].
- **Liability.** If you hire an authorized company to handle your hazardous waste, you share joint liability with it[^lgpgir].

For the scrap you sell, what backs your records is the evidence for each load that leaves. Asking your buyer for it is part of the operational control and the documented information the standard asks you to keep[^iso14001-2026]:

- Weighbridge ticket with gross, tare and net weight.
- CFDI for the sale and Carta Porte for the haul.
- Documented final destination: which plant the material reached.
- A recycling certificate with a folio that can be verified. See [what it should include](https://bluegreenmaterials.com/en/recycling-certificate).

## What Bluegreen gives you

Bluegreen does not certify management systems and holds no ISO 14001 certification. What it delivers for each lot it buys is evidence for your system:

- **Lot documents**: CFDI 4.0, Carta Porte 3.1 and weighbridge tickets with photos. Net weight is gross minus tare.
- **Certificate with a folio**: Verifiable online without an account: the verification shows the document's fingerprint so an auditor can compare it with their copy.
- **Net impact**: CO₂e avoided on what reached the mill, minus the transport of each haul. The current factors are preliminary and the certificate is not presented as verified. See [the methodology](https://bluegreenmaterials.com/en/impact-methodology).

If you generate scrap and want this evidence for your lots, see [sell scrap metal](https://bluegreenmaterials.com/en/sell-scrap-metal).
