5. 5 Registries are electronic databases Track holdings of units in accounts for Parties and entities Track transactions of all units Networked with each other over the internet National registries Established by Annex B Parties Allow the retirement of assigned amounts for compliance purposes CDM registry Established by the CDM Executive Board for non-Annex I Parties Specifically for the management of credits from CDM projects What registries do

8. 8 Transaction types IssuanceInitial creation of units (AAU, RMU, CER) ConversionTransforming AAUs or RMUs to ERUs for a JI project External transferMoving units to another registry CancellationDisabling the units from use against a target ReplacementReplacing tCERs or lCERs with more permanent units RetirementSetting aside units for use against a target Carry-overChanging unit validity to next commitment period Expiry Date ChangeAmending the lifetime of tCERs or lCERs

9. 9 Sufficient harmonization International rules define Basic registry requirements (decision 19/CP.7)  Parties have significant scope to implement as they wish Basic data exchange standards (decision 24/CP.8)  Recognized that exact technical specifications are needed Detailed specifications of the data exchange standards Coordinate processing undertaken in all registry systems Version 1.0 developed by the secretariat, with registry developers Procedures for use and further development to be implemented through cooperation among registry system administrators

10. 10 Secure communications over the Internet Transaction processing sequences Reconciliation processing sequences Message formats to ensure all communications can be read, including serial, account and transaction numbers ITL response codes to indicate negative check results ITL notifications and other administrative processes Initialization and testing of communications with the ITL Change management procedures for the standards Data exchange standards

11. 11 COP 10 requested consultations on Checks to be performed by the ITL Conformity of the checks with relevant COP decisions Pre-sessional consultations
