ISO 14001, the environmental management system

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 achieved¹.

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 exclusions¹.

• 670,000+certified organizations worldwide, according to the 2024 ISO Survey ²
• 170+countries where it is used ³
• 2026year of the fourth edition, published on 15 April ¹

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 parts¹.

1. 01

   Plan

   Set the environmental objectives and the processes needed to deliver results in line with the environmental policy.

2. 02

   Do

   Implement the processes as planned.

3. 03

   Check

   Monitor and measure the processes against the environmental policy, its commitments, objectives and operating criteria, and report the results.

4. 04

   Act

   Take actions to continually improve.

The requirements, clause by clause

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 chain².

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 audits³.

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 body¹. Certification is optional³.

1. 01

   Implement the full system

   All requirements, without exclusions, working and with their documented information¹.

2. 02

   Choose a certification body

   ISO does not certify or issue certificates: external bodies do. ISO recommends evaluating several and checking whether they are accredited⁴.

3. 03

   Check its accreditation

   Accreditation is the formal recognition given by an independent body, known as an accreditation body⁴. In Mexico, ema accredits certification bodies⁵.

4. 04

   Audit and certification

   The body assesses your system and, if it conforms, issues the certificate: written assurance that it meets the requirements⁴.

5. 05

   Name the edition

   ISO asks you to say "certified to ISO 14001:2026", not just "ISO 14001"¹.

In Mexico, the 2015 edition was adopted as NMX-SAA-14001-IMNC-2015, identical to ISO 14001:2015⁶. If your certificate is to that edition, ISO asks you to consult your certification body on the transition⁷.

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 them⁸.

• ISO 14001

  An international management system standard. It is certified by an external body; that body being accredited is advisable, not mandatory⁴.

• National Environmental Audit Programme

  A PROFEPA programme. The audit examines the company's operations, the pollution and risk they generate and their compliance with regulations⁸. It grants Clean Industry (Industria Limpia), Environmental Quality or Tourism Environmental Quality certificates, depending on the sector, valid for two years⁹.

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 performance¹.

For waste, the reference law in Mexico is the LGPGIR¹⁰:

• A large generator is anyone who generates 10 tonnes or more of waste per year¹⁰.
• 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 authority¹⁰.
• Hazardous waste. Large generators register with SEMARNAT, keep a log and file an annual report; small generators also register and keep a log¹⁰.
• Liability. If you hire an authorized company to handle your hazardous waste, you share joint liability with it¹⁰.

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 keep¹:

• 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.

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.

If you generate scrap and want this evidence for your lots, see sell scrap metal.
