Before the Article 6.4 Supervisory Body’s 10th meeting from 26 February to 1 March 2024, Carbon Market Watch prepared inputs on the draft document, “Concept note: Operation of the mechanism registry (v01.0)”. The mechanism registry will be a core part of the Article 6 infrastructure, and all activity- and unit-related data must be made accessible to the public in a user-friendly manner. Such data must be viewable in a “live manner” on a public interface of the mechanism registry that is machine-readable and updated in real time (or at regular intervals, e.g. weekly), which is already widely practiced on the voluntary carbon market. For full details, please consult our submission below.
