Gap analysis
We review the existing EMS clause by clause against ISO 14001:2026. We identify which documents, controls, context analyses and audit procedures need updating, and prioritise them by impact on the transition audit.

Transition to ISO 14001:2026
ISO 14001:2026 was published on 15 April 2026. Organisations certified under ISO 14001:2015 have until 30 April 2029 to complete the transition. We guide SMEs and mid-market companies through that change without any interruption to their certification.
ISO 14001:2026 is an evolution, not a rewrite. The High Level Structure (Annex SL) remains intact and no requirement from the 2015 version has been removed. Changes are concentrated in four areas: clause 4.1 broadens the organisational context to explicitly incorporate biodiversity, ecosystem health, pollution levels and the availability of natural resources alongside climate change; clause 6 strengthens the management of environmental risks and opportunities and introduces a new sub-clause 6.3 for structured planning of changes to the environmental management system (EMS); clause 8.1 extends operational control to suppliers, contractors and outsourced processes, requiring environmental criteria to be integrated into the supply chain; and internal audit requirements are clarified so that audit programmes reflect the updated standard.
For organisations with a mature EMS, the transition effort typically focuses on reviewing the context and interested-parties analysis (clauses 4.1 and 4.2), updating the risk analysis to incorporate physical and climate-transition risks, extending value-chain controls, and preparing for the transition audit with the certification body. According to data from leading certifiers, most mature environmental management programmes require between 30 and 90 person-hours of focused work to complete the transition. For systems that have not been updated in some time, the effort may be greater and preparation should begin as soon as possible.
Since 2007, Summum Calidad has supported organisations in Castilla y León and the Canary Islands in the implementation and renewal of ISO environmental management systems. We are not a certification body: certification is issued by an accredited third party (AENOR, Bureau Veritas, SGS, TÜV, DNV…). Our work consists in getting the EMS fully ready so that the certifier's transition audit is passed first time, with updated documentation, trained staff and processes aligned with the new requirements.
The Transition to ISO 14001:2026 process.
The process · four stagesEMS update
We review and update the context analysis (biodiversity, climate, ecosystems), the aspects and impacts register, the risk and opportunities matrix, value-chain controls (8.1) and the internal audit programme. We deliver documentation ready to use.
Training and internal audit
We train the EMS team on the standard's changes. We carry out a full internal audit in line with ISO 14001:2026 to verify conformity before the official audit and to detect any minor nonconformity in time.
Transition audit support
We prepare the opening meeting, review the documentary evidence the organisation will present, and address the audit team's queries. After the audit, we manage the closure of any nonconformity identified until the certificate issued under the 2026 version is obtained.

Summum cluster
How it connects with its sisters.
The transition to ISO 14001:2026 intersects with sustainability reporting (ESG/CSRD managed by Summum Consultoría) and with the digitalisation of the EMS through process automation (Summum Sistemas).

If your organisation must report under CSRD, the transition to ISO 14001:2026 feeds directly into the environmental data of the sustainability report. Summum Consultoría manages ESG/CSRD reporting.

The new clause 4.1 reinforces the integration of climate change into the EMS; calculating and managing the carbon footprint is the natural next step once the transition is complete.

Digitalising EMS records and controls (environmental indicators, objective tracking, deviation alerts) reduces maintenance effort and facilitates follow-up audits.

When is the deadline to transition to ISO 14001:2026?
The deadline is 30 April 2029. From 1 October 2027, recertification audits will incorporate the requirements of the new version. Certificates issued under ISO 14001:2015 will expire on that date even if they are still in force; this is why it is advisable to start the transition well in advance and not to wait until the last audit cycle.
What are the most important changes in ISO 14001:2026 compared with the 2015 version?
There are four main changes: (1) clause 4.1 explicitly incorporates biodiversity, ecosystems and the availability of natural resources into the context analysis; (2) clause 6 strengthens environmental risk management and introduces structured planning of EMS changes (new 6.3); (3) clause 8.1 extends operational control to the entire value chain (suppliers and outsourced processes); and (4) internal audit requirements are clarified. No requirements from the 2015 version have been removed.
Do I need to recertify from scratch or is a transition audit sufficient?
There is no need to certify from scratch. Accredited certification bodies (AENOR, Bureau Veritas, SGS, DNV, TÜV…) offer specific transition audits that verify the changes made to the EMS. Once the audit is passed, the certifier issues a new certificate under the 2026 version without the need to repeat the entire initial process.
How long does the transition to ISO 14001:2026 take?
For organisations with a mature and well-documented EMS, the process typically requires between 3 and 6 months of work. The most time-consuming aspects are the review of the context and risk analysis, the extension of value-chain controls and team training. In more outdated systems the timeline may be longer. The recommended approach is to start the gap analysis now and not leave the transition to the last year before the deadline.
Does Summum Calidad certify my company to ISO 14001:2026?
No. Summum Calidad is a consultancy, not a certification body. Our work is to get your EMS fully updated and ready to pass the transition audit of the accredited certifier you already work with or choose. Certification is always issued by a third party accredited by ENAC or an equivalent body.
