Question 1

Which ISO standard does my CBAM verifier need to hold?

Accepted Answer

Your CBAM verifier must hold ISO 14065 accreditation from the national accreditation body of their country. ISO 14065 accredits the verification body — not the manufacturer. The verifier then applies ISO 14067 methodology to calculate your embedded carbon.

Question 2

What is the difference between ISO 14064 and ISO 14067?

Accepted Answer

ISO 14064 covers organisational and project-level GHG quantification. ISO 14067 covers carbon footprint of products — including embedded carbon in manufactured goods. For CBAM, ISO 14067 is the relevant calculation methodology standard.

Question 3

Do I as a manufacturer need to hold any ISO certification for CBAM?

Accepted Answer

No. Manufacturers do not need to hold any ISO certification for CBAM. You need to hire an ISO 14065 accredited verifier who will apply ISO 14067 methodology to calculate and verify your embedded carbon. The verifier holds the accreditation, not you.

Question 4

How much does CBAM third-party verification cost?

Accepted Answer

CBAM verification costs range from EUR 5,000–15,000 for small facilities, EUR 15,000–50,000 for mid-size facilities, and EUR 50,000–150,000+ for large industrial facilities. Costs depend on facility size, sector complexity, number of production lines, and verifier travel requirements.

Question 5

What is ISO/IEC 17029 and does it apply to CBAM?

Accepted Answer

ISO/IEC 17029 is the general conformity assessment standard for validation and verification bodies. It provides the framework within which ISO 14065 operates. For CBAM purposes, ISO 14065 (which references ISO/IEC 17029) is the specific standard to look for when selecting a verifier.

Question 6

What is a national accreditation body?

Accepted Answer

A national accreditation body (NAB) is the government-designated organisation that accredits verification bodies in each country. Examples: SANAS (South Africa), NABCB (India), TÜRKAK (Turkey), CNAS (China), DAkkS (Germany), UKAS (UK). The NAB confirms that a verification body meets ISO 14065 requirements.

Question 7

Can I use a verifier accredited by a foreign national accreditation body?

Accepted Answer

Yes. CBAM does not require the verifier to be accredited by the national accreditation body of the manufacturer's country. A German verifier (DAkkS accredited) can verify a South African manufacturer. However, local verifiers typically have lower travel costs and better knowledge of local grid emission factors.

Question 8

What is the CBAM verification requirement under Implementing Regulation 2023/1570?

Accepted Answer

CBAM Implementing Regulation 2023/1570 Article 8 requires that actual embedded carbon values used in CBAM declarations must be verified by a verification body accredited under ISO 14065 by a national accreditation body that is a member of the International Accreditation Forum (IAF).

Standard	What it covers	Who holds it	Relevant to CBAM?
ISO 14064 (Parts 1, 2, 3)	GHG quantification and reporting at organisational level (Part 1), project level (Part 2), and validation/verification (Part 3)	Manufacturers (Parts 1–2) and verifiers (Part 3)	Partially — Part 1 is used for organisational carbon footprints but is not the primary CBAM methodology
ISO 14065	Requirements for GHG validation and verification bodies — the accreditation standard for verifiers	Verification bodies (verifiers) — accredited by national accreditation bodies	Yes — this is what your verifier must hold
ISO 14067	Carbon footprint of products — quantification and communication. The methodology for calculating embedded carbon in manufactured goods	Applied by verifiers when calculating manufacturer's embedded carbon	Yes — this is the calculation methodology your verifier applies
ISO/IEC 17029	General requirements for validation and verification bodies — the broader conformity assessment framework within which ISO 14065 operates	Verification bodies	Indirectly — ISO 14065 references ISO/IEC 17029
