CBAM Verification: Carbon Border Adjustment Mechanism
CBAM is an EU regulation that applies a carbon price to certain imported goods. It is mandatory for EU importers, who must report embedded emissions and, to have purchase certificates reflecting those emissions from 2027 and onwards.
While non-EU producers are not directly regulated, they must provide reliable emissions data to their EU customers. Without verified data, importers must use default values, which can increase carbon costs.
As CBAM moves into its fully operational phase, emissions data will directly determine financial liability. Verification becomes essential when reporting actual emissions, supporting compliance and helping reduce costs across the supply chain.
Accredited third party verification will be mandatory for importers reporting actual emissions data. Importers using default values will not be subject to verification requirements.
What is CBAM Regulation?
The Carbon Border Adjustment Mechanism (CBAM) is a key pillar of the European Union’s strategy to prevent carbon leakage and ensure that international trade aligns with its climate objectives. CBAM initially applies to imports of carbon intensive products, including:
- aluminium
- cement
- electricity
- fertilizers
- hydrogen
- iron
- steel
By assigning an emissions cost to imported goods that mirrors the EU Emissions Trading System (EU ETS), CBAM creates a level playing field between EU and non EU producers.
Under the CBAM regulations, non-EU based producers (operators) of covered goods that export to the EU will need to:
- Calculate the embedded emissions of their products under the CBAM methodology
- Get third-party verification for the embedded emissions (verifier visits operator’s installation and issues a verification report)
- Provide data (calculation of emissions and verification report – “actual values”) for good covered by the CBAM regulation
Value of CBAM verification
Verification by an independent third-party means that you have CBAM reporting based on actual emissions data.
As a result, you:
- Reduce your financial exposure: The default values, as defined in the Commission Implementing Regulation and its Annexes published on 16 December 2025, are intentionally conservative and can significantly increase CBAM costs. If your production processes are less carbon‑intensive, using verified actual emissions data can substantially lower EU importers CBAM liability.
- Improve operational efficiency: Reporting actual emissions data provides deeper visibility into your operations. It helps identify inefficiencies, uncover decarbonization opportunities, and drive operational improvements that enhance productivity and cost efficiency.
- Strengthen credibility and trust: Verified emissions data demonstrates a strong commitment to regulatory compliance and sustainability. This transparency builds confidence among customers, investors, and other stakeholders, supporting long‑term business relationships.
- Future‑proof your business against evolving regulations: Implementing CBAM‑compliant systems for emissions data collection, monitoring, and accounting prepares your organization for future CBAM scope expansions and the potential introduction of similar carbon border mechanisms in other markets.

As a DNV customer, you also get access to a suite of digital tools that can help you ensure compliance, continually improve and manage your entire certification journey with us.
Learn about the verification process
The verification process includes the following key steps:
- Perform a strategic and risk based assessment
- Review documentation related to the calculation of embedded emissions and the applicable monitoring procedures
- Conduct your own on site assessment of the completeness of emission sources and flows, the accuracy and traceability of data, and the correct implementation of the monitoring methodology
- Undergo an independent review and receive the Verification Report, which includes the opinion statement, that can be shared with customers.
FAQ – CBAM
-
CBAM (Carbon Border Adjustment Mechanism) is an EU environmental policy designed to prevent carbon leakage by applying a carbon cost to imports of carbon intensive products - such as iron, steel, aluminium, cement, fertilizers, electricity, and hydrogen – such aligned with the EU Emissions Trading System (EU ETS), ensuring fair competition between EU and non EU producers.
-
The CBAM Regulation is the EU legal framework that establishes how the Carbon Border Adjustment Mechanism is implemented, defining its scope, covered products, reporting and compliance obligations, and specifying the conditions for granting accreditation to verifiers.
