Question 1

What is ISO 14065 and what does it govern?

Accepted Answer

ISO 14065:2020 is the international standard that specifies requirements for bodies performing validation and verification of environmental information — including greenhouse gas (GHG) inventories, GHG project emission reductions, and sustainability assertions. It is the accreditation standard that validation and verification bodies (VVBs) must meet to be recognised as competent to conduct ISO 14064-3 GHG verification engagements. ISO 14065 governs the competence, impartiality, and consistent operation of verification bodies — requiring them to demonstrate technical expertise in the GHG assertions they verify, maintain independence from the organisations they audit, operate documented management systems for verification processes, and participate in proficiency testing and peer review. National accreditation bodies (such as UKAS in the UK, DAkkS in Germany, and RvA in the Netherlands) assess verification bodies against ISO 14065 requirements before granting accreditation. For organisations subject to CSRD, their sustainability statement assurance provider must be an accredited statutory auditor or, for GHG-specific elements, an ISO 14065-accredited verification body. Ledger2Carbon's ISO 14065 readiness support platform helps organisations prepare the documentation that these accredited bodies require to conduct verification engagements efficiently.

Question 2

How does Ledger2Carbon provide ISO 14065 readiness support?

Accepted Answer

Ledger2Carbon's ISO 14065 readiness support platform prepares organisations for verification body engagements by maintaining the evidence file structure and process documentation that ISO 14065-accredited verifiers need to conduct their assessment efficiently. The platform organises GHG assertion documentation in a structure aligned to the verification body's typical engagement workflow — including the GHG inventory or project documentation, methodology justifications, activity data evidence, emission factor provenance records, uncertainty assessments, and completeness checks — so that the verifier can proceed directly to substantive testing rather than spending billable time collecting disorganised documentation. Pre-engagement readiness checks identify non-conformance risks and documentation gaps before the verifier arrives, allowing organisations to resolve issues at low cost. Role-based access controls allow verification body team members to be granted structured read access to the specific evidence packages within their engagement scope.

Question 3

Why is ISO 14065 readiness support important for carbon emissions validation?

Accepted Answer

ISO 14065 readiness support is important because the quality and organisation of evidence documentation directly determines the efficiency, cost, and outcome of a verification body engagement. ISO 14065-accredited verifiers follow structured engagement procedures — planning, risk assessment, substantive testing, and reporting — and their ability to complete each stage efficiently depends on the clarity and completeness of the documentation they receive. Disorganised evidence files force verifiers to raise repeated information requests, extending the engagement timeline and increasing billable hours. Incomplete methodology documentation leads to non-conformance findings that must be resolved before a positive verification statement can be issued. Missing linkage between activity data and calculation results creates material misstatement risks that verifiers are required to report. Organisations that invest in ISO 14065 readiness support — maintaining structured, continuously updated evidence files throughout the year rather than assembling documentation at year-end — consistently complete verification engagements faster, at lower cost, and with fewer findings than organisations that treat verification preparation as an annual sprint.

Question 4

What services does Ledger2Carbon offer for ISO 14065 compliance readiness?

Accepted Answer

Ledger2Carbon's ISO 14065 compliance readiness services cover four areas. Evidence structure management — the platform maintains GHG assertion documentation in a structured repository with evidence linked to each result, methodology, and emission source, organised in the format that ISO 14065-accredited verification bodies expect. Pre-engagement readiness assessment — built-in completeness and accuracy checks identify non-conformance risks, missing evidence, and undocumented assumptions before the verification body engagement begins, when they can be addressed without delaying the verification timeline. Verification body selection support — guidance on identifying ISO 14065-accredited verification bodies with relevant sector expertise for your GHG assertion type (ISO 14064-1 corporate inventory, ISO 14064-2 project reductions, or CSRD sustainability statement assurance). Ongoing verification alignment — repeatable annual workflows that maintain verification readiness continuously rather than requiring intensive year-end preparation, reducing the cost and duration of each successive verification engagement.

Question 5

How does ISO 14065 readiness relate to CSRD assurance requirements?

Accepted Answer

ISO 14065 readiness is directly relevant to CSRD assurance because the GHG data disclosed in CSRD sustainability statements under ESRS E1 (Climate Change) must be capable of withstanding external assurance by an accredited statutory auditor or equivalent assurance provider. CSRD requires limited assurance of the full sustainability statement from the first reporting cycle (2025 for large companies) and is expected to escalate to reasonable assurance from 2028. Assurance providers conducting CSRD sustainability statement review under ISAE 3000 (for sustainability information generally) and ISAE 3410 (specifically for GHG statements) apply procedures that are substantively equivalent to ISO 14064-3 verification — assessing the completeness and accuracy of GHG data, the appropriateness of methodologies, and the consistency of boundary and reporting decisions. Organisations that have achieved ISO 14065 verification readiness for their GHG inventory therefore have a strong foundation for the CSRD assurance process — the same structured evidence repository, methodology documentation, and data consistency with financial records that ISO 14065 verifiers require are precisely what CSRD assurance providers assess. Ledger2Carbon's platform is designed to serve both contexts from a single evidence base.
