CBAM Verifiers: Factory Inspections

Writer's picture: Arne MielkenArne Mielken

CBAM verifiers are coming! From 2026, factories must verify carbon emissions' data with accredited experts. Are you prepared?


As the European Union’s Carbon Border Adjustment Mechanism (CBAM) moves toward its full implementation in 2026, businesses face a critical shift: the introduction of accredited verifiers. These verifiers will play a vital role in ensuring the accuracy of carbon emissions data reported for imported goods. This blog explores what businesses need to know and how to prepare for this new layer of scrutiny.


What’s changing?


Mandatory Emissions Verification

Starting in 2026, companies importing goods into the EU under CBAM must provide detailed data on the carbon emissions embedded in their products. Businesses opting to use actual emissions values rather than default values will need this data verified by an accredited verifier before submission to the CBAM registry.


Verifier Accreditation Process

The EU is implementing a rigorous accreditation system:

  • National Accreditation Bodies (NABs) will oversee the accreditation of verifiers in line with legal and regulatory standards such as EN ISO 17011 and EU-specific requirements.

  • This ensures that verifiers are both qualified and impartial, giving confidence in the reliability of the emissions data.


Timeline for Verification

Key milestones to note:

  1. 2026: Accreditation of verifiers begins.

  2. Early 2027: Verification processes commence.

  3. May 31, 2027: The first CBAM declarations with verified emissions must be submitted.


Standardised Reporting and Verification

The EU is aligning CBAM verification standards with its Emissions Trading System (ETS) to ensure consistency. The process will adhere to EN ISO/IEC 14065, setting a high bar for transparency, reliability, and environmental accountability.

Accredited verifiers will:

  • Conduct on-site factory inspections to review operations and emissions records.

  • Ensure compliance with CBAM’s stringent methodology.

  • Provide verification reports that include detailed assessments of the emissions methodology, operator details, and a statement on data accuracy.


Impact on Suppliers and Importers


Increased Responsibility for Suppliers

Suppliers exporting to the EU will bear the responsibility of monitoring, calculating, and reporting emissions data. Collaboration with accredited verifiers will be crucial to meet EU expectations.

Administrative Challenges

For operators, preparing for verifications will require:

  • Meticulous tracking of emissions data.

  • Ensuring internal compliance processes are robust.

  • Managing inspections and addressing potential discrepancies or non-compliance issues.

Cost Implications

The verification process will incur additional costs for hiring accredited verifiers and preparing detailed reports. Importers and customers may ultimately share this financial burden as businesses adjust pricing to offset compliance costs.

Opportunities for Collaboration and Simplification

In 2025, the EU will launch a dedicated portal to facilitate data sharing among third-country operators, verifiers, and EU declarants. This platform aims to:

  • Simplify reporting processes.

  • Enhance collaboration while protecting sensitive business information.

By leveraging these tools, businesses can streamline their CBAM compliance efforts and build stronger partnerships across their supply chains.


Preparing for 2026 and Beyond

The road to CBAM’s full implementation presents both challenges and opportunities for businesses. To stay ahead:

  • Audit your supply chain: Ensure suppliers are monitoring and calculating emissions data correctly.

  • Engage with verifiers early: Build relationships with accredited verifiers and develop internal processes for verification.

  • Invest in training: Equip your teams with the knowledge needed to navigate CBAM compliance effectively.


Final Thoughts

As CBAM evolves, it’s not just about compliance—it’s about embracing a future of greater transparency and environmental accountability. Accredited verifiers will be your partners in this journey, helping ensure your emissions data stands up to scrutiny and reflects your commitment to sustainable trade.
