CBAM Verification

Support your EU customers with Carbon Border Adjustment Mechanism (CBAM)-ready emissions data.

CBAM is raising the bar for emissions reporting

Suppliers that provide accurate, verifiable emissions data will be better positioned to support EU customers and protect market access

As CBAM requirements evolve, your customers need reliable emissions data they can use. A repeatable, verification-ready approach can help you stay competitive.

Providing verified emissions data is no longer just a compliance exercise. It is becoming a competitive requirement. When emissions data cannot be verified, EU importers may need to rely on default values, which can increase costs and reduce confidence in your reporting.

We help you strengthen the processes, controls, and evidence behind your emissions data, making it verification-ready and fit for customer use. This helps your customers rely on your figures, supports long-term compliance, and protects your position as a preferred supplier as CBAM requirements continue to evolve.

FAQ

CBAM frequently asked questions

Find out more about EU CBAM, verification, and the value of partnering with BSI.

CBAM (Carbon Border Adjustment Mechanism) is an EU regulation that puts a carbon price on imported goods based on their embedded emissions.

CBAM aligns the carbon cost of imports with EU-produced goods to create fair competition and drive lower-emission production globally.

While the EU importer is responsible for submitting the annual CBAM declaration and meeting the legal reporting requirements, suppliers play a critical role by providing accurate, verified emissions data. Without reliable emissions information from suppliers, importers may be unable to report actual emissions and could face higher CBAM-related costs.
CBAM usually refers to the EU Carbon Border Adjustment Mechanism, which is the first regulation of its kind and currently the most developed.

Other versions, such as the pending UK CBAM or similar proposed regulations in other regions, follow the same principle of pricing carbon on imports, but differ in scope, timelines, and specific requirements. For organizations operating globally, this means requirements may vary by market over time.

BSI currently offers verification aligned to EU CBAM requirements, supporting organizations that need compliant, independently verified emissions data for EU reporting. We are monitoring these new requirements and are readying support options.
CBAM third-party verification is the independent assessment of your embedded emissions data by an accredited verifier. It confirms that the emissions data provided to your EU customers is accurate, complete and aligned with CBAM requirements.

Verified emissions data helps EU importers meet their reporting obligations and avoid relying on default values, which may result in higher CBAM costs. By providing verification-ready data, you can strengthen customer confidence, support compliance across the supply chain, and maintain your competitiveness as CBAM requirements continue to evolve.
CBAM verification helps ensure your emissions data is accurate, compliant and ready for CBAM reporting. Independent verification reduces the risk of reporting errors, rejected declarations and compliance issues across the supply chain.

Verified emissions data helps EU importers avoid relying on default values, which may result in higher CBAM costs. It also increases confidence in your reporting, helping your customers meet their obligations and rely on your data.

Over time, verification helps you build a repeatable, audit-ready process that supports ongoing compliance and positions your organization as a credible supplier.
The CBAM verification process is a structured, independent assessment of your emissions data to confirm compliance.

It typically includes the following steps:

Application: Provide details of your monitoring plan, system boundaries, and embedded emissions.

Planning: BSI review, analyze, and assess risks to develop detailed plans.

Execution: BSI conducts verification through physical and remote site visits.

Findings: Misstatements or non-conformances must be resolved if they materially impact the claim.

Conclusions: Final opinion; all material issues must be addressed for a positive opinion.

Independent review: Ensures minimal risk before issuing the opinion.

Opinion and report: Final opinion issued.
CBAM verification will form part of an annual reporting cycle.

The first verification will cover full-year 2026 import emissions data and can be completed between early 2027 and 30 September 2027. From 2027 onwards, emissions data for the previous reporting year must be verified each year to support CBAM declarations. Because verification is recurring, suppliers need a repeatable process to collect, verify, and improve emissions data ahead of each submission.
CBAM may still be relevant, even if you don’t supply directly into the EU.

Providing verified emissions data can strengthen your position in the supply chain. It can help you maintain relationships and improve your competitiveness when entering new markets. For example, if you act as a supplier to an organization that CBAM is applicable to, they will need your reliable accurate data.

Additionally, other markets are looking at implementing similar requirements to the EU. Readying your data now can ease the burden of future requirements or scope extension.
Standards like those below can support the structure, controls, and documentation needed to meet CBAM requirements effectively.

ISO 14001 (Environmental Management) helps you manage environmental impacts and maintain compliant processes.

ISO 50001 (Energy Management) supports control of energy use and related emissions at facility level.

ISO 14064 (Greenhouse Gas) provides a framework for measuring and reporting emissions aligned to verification requirements.

Together, these systems help you build consistent, audit-ready emissions data and strengthen your readiness for CBAM verification.
In some cases, yes.

If BSI already provides greenhouse gas (GHG) verification services for the same sites and a similar scope, there may be opportunities to align activities and improve audit efficiency. For example, CBAM verification may overlap with organizational-level GHG verification against ISO 14064 or the GHG Protocol.

While management system certifications such as environmental, health and safety (EHS) or energy management typically have a different audit scope, existing site knowledge can help make the CBAM verification process more effective. Combining assurance activities where appropriate can reduce disruption, improve consistency and increase confidence in your emissions data.
You can build CBAM knowledge across your organization through targeted training and structured learning pathways.

BSI offers a dedicated CBAM training course to help you understand requirements, reporting expectations, and verification readiness. This gives your team a practical foundation to manage compliance effectively.

You can also extend learning through BSI’s wider sustainability portfolio, including carbon accounting, emissions reporting, and environmental management. These courses help you strengthen capability in areas directly supporting CBAM.
BSI is progressing accreditation for EU CBAM verification.

Accreditation matters because it confirms that verification is carried out by a competent, independent, and approved third party, meeting strict EU requirements. Without accredited verification, emissions data may not be accepted for CBAM reporting.

By being accredited, BSI ensures its CBAM verification services meet the required standards for credibility, regulatory acceptance, and global consistency. Giving you confidence that your data is verified to the level expected by EU authorities.
Yes, you can work with BSI.

CBAM verification is part of an annual cycle, so you can transfer to BSI for future reporting periods without disruption. The first CBAM report is to be verified and submitted in 2027, so if you are working with other providers for pre-verification, feel free to select BSI as the service provider for your formal CBAM verification.

By working with BSI, you can benefit from a structured verification process and broader support across training, pre-verification, and assurance.
