ISO 14065 accreditation consulting for environmental claims that stand up to scrutiny.

What it is

What is ISO 14065 and what is it used for?

ISO 14065 sets out the principles and requirements for bodies that validate and verify environmental information statements. It is the environmental sector application of ISO/IEC 17029, the general standard for validation and verification bodies: ISO/IEC 17029 supplies the common rules on competence, impartiality and consistent operation, and ISO 14065 adds what is specific to environmental claims. The two are read and assessed together.

The scope is broad. ISO describes the 2020 edition as covering all forms of environmental information, including greenhouse gas statements, carbon and water footprints, environmental labelling claims, sustainability reporting, and information behind green bonds and other financial instruments. Programme owners, regulators and accreditation bodies use it to judge whether a body is competent to give an opinion on those claims.

Current edition. ISO 14065:2020, the third edition, published in December 2020, replaced ISO 14065:2013. ISO completed a systematic review in March 2026 and confirmed the 2020 edition, with no revision shown as under development. It is used together with ISO/IEC 17029:2019, and competence requirements for validation and verification teams sit in the companion standard ISO 14066:2023.

Who it is for

Who needs ISO 14065 accreditation?

ISO 14065 is written for the checker, not the claimant. A company reporting its own emissions does not implement it; the body that verifies that report does. Bodies come to Sterling for ISO 14065 from four starting points:

• Clients want an accredited opinion. Reporters, manufacturers and project developers ask their verifier for proof of accreditation, because their own customers and lenders ask them.
• A tender or programme owner makes it a condition. Carbon crediting, labelling and reporting programmes often admit only accredited validation and verification bodies, and set their own competence rules on top of ISO 14065.
• A regulator relies on third-party verification. Where emissions reporting or disclosure rules call for independent assurance, an accredited scope is usually how the verifier demonstrates it is fit to provide it.
• A group company is adding verification to its services. A certification body, inspection body, laboratory or consultancy group moving into environmental assurance needs a separate, impartial structure and an accreditation scope of its own.

Requirements

What are the main ISO 14065 requirements?

Because ISO 14065 applies ISO/IEC 17029 to environmental information, its requirements fall into the areas ISO names for both standards. The list below is a plain-language map of those areas, not a substitute for the standards; during the programme your body is checked against the full text of ISO 14065, ISO/IEC 17029 and every programme on the intended scope.

• General principles: the principles behind every validation and verification opinion, applied before any detailed rule.
• Impartiality: identify and manage threats from ownership, other services, fees and relationships, so no environmental claim is judged by someone with a stake in it.
• Competence of personnel: a managed process, specified in ISO 14065:2020, 7.3, for defining, evaluating and maintaining competence; team competence itself is set out in ISO 14066.
• Consistent operation: the same controlled path for every engagement, from agreement and planning through evidence gathering to the opinion and its records.
• Validation: confirm that a forward-looking claim, such as projected emission reductions, is plausible for its intended use.
• Verification: confirm that a claim about past performance, such as an emissions inventory or a footprint, is truthfully stated.
• Environmental sector requirements: the additional rules ISO 14065 adds for greenhouse gas statements, footprints, labelling claims, sustainability reporting and green finance information.
• Programme rules: apply the requirements of each validation or verification programme you operate under, where they add to the standard.

Accreditation process

How do you get ISO 14065 accreditation?

Build a body that operates to both standards, run real engagements, then apply. The accreditation body assesses the body and decides on the scope; Sterling prepares you for that assessment and never takes part in the decision.

1. 01
   Define the scope you will apply for.Choose validation, verification or both, the types of environmental information, the programmes and technical areas, and the accreditation body that will assess you.
2. 02
   Gap analysis: compare the body with ISO 14065, ISO/IEC 17029 and each programme.Structure, impartiality, competence, engagement process and records are reviewed; what works stays, and actions get owners and dates.
3. 03
   Implement, qualify people and complete engagements.Put procedures into use, authorise verifiers, validators and independent reviewers, and finish real engagements under the new system.
4. 04
   Audit, review and close the findings.An internal audit traces engagement files from agreement to opinion, management review follows, and we raise findings first so they are closed with evidence before you apply.
5. 05
   Complete the accreditation body's assessment.Document review, the office assessment and witnessed engagements; close any nonconformities, receive the decision on your scope, then maintain it through surveillance and reassessment.

Check the route before you sign. Confirm which accreditation body will assess you, that it accredits validation and verification bodies for the programmes you need, whether it is recognised under the Global ACI arrangement, and what it requires before a first witnessed engagement. Verify each answer with the accreditation body and the programme owner directly.

Cost

How much does ISO 14065 accreditation cost?

The investment depends on what the body already has and the scope it wants. A certification body adding greenhouse gas verification to an existing ISO/IEC 17021-1 system starts in a very different place from a new firm building its first quality system. Every Sterling proposal shows each component and one all-inclusive proposal.

Timeline

How long does ISO 14065 accreditation take?

Measure it in months. The pacing item is not paperwork but engagements: assessors want completed files to sample and a live engagement to witness, so the body must work under its new procedures before it can be assessed. Scheduling, closing findings and the decision then add time outside your control; we track each milestone in Effivity.

Your engagement

What your ISO 14065 engagement includes

One team takes the body from gap analysis to the accreditation decision under one all-inclusive proposal. You choose the level of support: Design™, where we guide and your people build, or Drive™, where we manage the build alongside your team; they are alternatives, not stages. Sustain™ keeps the scope healthy after accreditation, and Automate™ is Effivity.

• Scope, gap analysis and plan

  Programmes, technical areas, owners and dates agreed before work begins.

• Impartiality and structure

  Threat analysis, safeguards and the governance that keeps opinions independent of commercial pressure.

• Competence framework

  Criteria per role and technical area, evaluation and authorisation records, aligned with ISO 14066.

• Engagement procedures and templates

  From agreement and planning to sampling, review and the opinion, written with your technical team.

• Training for the team

  Internal auditor training, as applicable to your standard, and preferential Sterling Academy access, including complimentary awareness training for your people as part of the engagement.

• Internal audit and assessment readiness

  File-based internal audit, management review and support through the accreditation assessment until the decision.

Sterling does not accredit, validate or verify; the accreditation decision remains with the accreditation body.
