Technical committee
The Technical Committee (TC) is composed of the lead auditors of all Certifying Bodies (CBs). It advises the CCvD on how to interpret the CO₂ Performance Scale and manage the certification process. One of the main tasks of the committee is to discuss topics related to harmonization. Once these topics are approved by the CCvD, they become official decisions known as harmonization acts.
