European Union: EU Issues CBAM Verifier Accreditation Guidance for 2026

On 24 August 2026, the European Commission published comprehensive Guidance on CBAM Verification and Accreditation, addressing verifiers and National Accreditation Bodies (NABs) operating under the Carbon Border Adjustment Mechanism (CBAM) definitive period, which commenced on 1 January 2026. This guidance, developed pursuant to Article 16 of Regulation (EU) 2023/956 (CBAM Regulation) and Implementing Regulation (EU) 2023/1773, clarifies the accreditation requirements for verifiers, the verification process for embedded emissions reports, and the oversight responsibilities of NABs. It establishes a harmonized EU-wide approach to ensure the reliability of emissions data submitted by non-EU producers and importers, covering sectors such as cement, iron and steel, aluminium, fertilizers, electricity, and hydrogen. The document also details the transitional measures for verifiers already accredited under national schemes, the peer evaluation process among NABs, and the Commission’s supervisory role via the CBAM Verifier Portal. This guidance is legally binding for all verifiers seeking accreditation and for NABs granting such accreditation, effective immediately.

Key Takeaways

  • Verifier Accreditation Standards: Verifiers must demonstrate competence in ISO 14065:2020, sector-specific CBAM methodologies, and independence from operators, with mandatory witness audits by NABs to ensure consistent application of verification principles across the EU.
  • Embedded Emissions Verification: The guidance prescribes detailed verification steps for direct and indirect emissions, including electricity consumption, precursor goods, and system boundaries aligned with the EU ETS Monitoring and Reporting Regulation, reducing the risk of under-reporting.
  • NAB Oversight and Peer Review: National Accreditation Bodies are required to participate in EA (European co-operation for Accreditation) peer evaluations and report annually to the Commission on accredited verifier performance, creating a robust quality assurance loop.
