3. Until the establishment of the Union registry, a certification scheme shall establish and duly maintain a certification registry to make publicly accessible in a secure way the information related to the certification process, including the certificates of compliance and updated certificates of compliance, containing, as a minimum, the information set out in Annex III, to enable the tracing of the quantity of units certified in accordance with Article 9.
A certification registry shall use automated systems, including electronic templates, and shall be interoperable with registries of other recognised certification schemes in order to avoid double counting.
The Commission shall adopt implementing acts setting out the structure, format and technical details of the certification registries and of the recording, holding or use of certified units, including as referred to in this paragraph. Those implementing acts shall be adopted in accordance with the examination procedure referred to in Article 17.
