Under CBAM, only verifiers accredited by EU National Accreditation Bodies (NABs) can verify the total embedded emissions declared in an importer’s CBAM declaration. To support verification bodies both within and outside the EU, this webinar coveredCBAM accreditation and verification processes. Together with subject matter experts, DG TAXUD presented the practical aspects of accreditationand verificationto a target audience of EU ETS verifiers and new verifiers who are potential applicants for CBAM accreditation.
