CDM Registry
Institutional background
The Conference of the Parties serving as the meeting of the Parties to the Kyoto Protocol on its first session, held at Montreal from 28 November to 10 December 2005, established that the CDM Executive Board shall develop and maintain the CDM registry according to the requirements set out in Appendix D to the report (FCCC/KP/CMP/2005/8/Add.1).
These requirements specify that the CDM registry is to be in the form of a standardized electronic database that ensures the accurate accounting of the issuance, holding and acquisition of CERs. In order to do so, Appendix D to Decision 3/CMP.1 provides guidance on the different account types to be available in the CDM registry, provisions for unique serial numbers, conditions for the forwarding of CERs and publicly available information about the operation of the CDM registry.
This document also establishes that
The Executive Board shall establish and maintain a CDM registry to ensure the accurate accounting of the issuance, holding, transfer and acquisition of CERs by Parties not included in Annex I.
The Executive Board shall identify a registry administrator to maintain the registry under its authority.
(3/CMP.1, Annex, Appendix D, paragraph 1). The Executive Board of the Clean Development Mechanism designated the UNFCCC Secretariat as the CDM registry administrator at its thirteenth meeting.
The Annual report (2003–2004) of the Executive Board of the clean development mechanism to the Conference of the Parties also states that the Board agreed that the secretariat is to be the CDM registry administrator with responsibility, under the authority of the Board, for implementing and operating the CDM registry (CP/2004/2/ paragraph 59).
Publicly available information can be found on the issuance of CERs section.
Information about the amount of CERs allocated to the Adaptation Fund account can be found here
The Executive Board provided further guidance for the work of the CDM registry at its subsequent meetings. The reports of each meeting containing the corresponding decisions can be found on the EB section .

An attempt was made from outside the UNFCCC secretariat to execute an unauthorised transfer of certified emission reductions (CERs) from the CDM registry. Internal security procedures prevented the transfer from being executed, and no CERs were transferred. The owners of the accounts involved have been notified by the secretariat. The secretariat is investigating the incident to ensure continuous safe operation of the registry.

Due to scheduled maintenance of the International Transaction Log the CDM Registry will be unavailable to process transactions or issuance/account related matters from 4-10 November 2011. We kindly request the understanding of project participants and account representatives during this outage period which is aimed to improve service requirements and benefit users of the CDM Registry.

09 Feb 11 — Important announcement
Due to the recent closure of EU national registries for security reasons, the CDM Registry kindly requests the understanding of project participants for the undue delay in processing CER forwarding transactions. As soon as the national registries concerned are available the requested action will be taken as soon as possible.
07 Dec 09 — Electronic interface update
Updates to the electronic interface designed to facilitate requests for changes to MOC statements form focal point entities were introduced on 30 November 2009. The changes and improvements include a new ‘action-based’ interface where focal point entities are invited to use the new functions available which, amongst others, provide for the possibility to upload additional documents, including Letters of Approval (LoAs), via the online interface.
The secretariat continues to test and modify new features which will lead into the next phase of development expected in the first half of 2010.
04 Sep 09 — Electronic interface for requesting changes to the MOC, addition/withdrawal of project participants or updating contact details
Following the guidance provided in the Procedures for Modalities of Communication between Project Participants and the Executive Board adopted at EB45, the secretariat is pleased to announce that a pilot interface was deployed on 12 August 2009 (version 1) as a first step towards a full online and paperless process.
Authorised signatories of project participants and focal point entities that wish to request changes to existing Modalities of Communication, addition/withdrawal of project participants or updating contact details should use the electronic F-CDM-MOC form available on the link provided in the registration and issuance emails.
It is no longer necessary to submit the hard copy of the MOC form or any of its annexes, provided the scanned documents have been duly signed and uploaded through this interface. Please note, however, that these documents should be available upon request should the secretariat deem it necessary to verify the originals.
For security reasons, all communication must be channelled via the authorised signatory/ies of the focal point entity and each request made through the electronic interface should be made using the name and email address that has been officially registered in the modalities of communication.

24 Oct 08 — CDM registry starts live operations with EU registries
The CDM registry is pleased to announce that, as a result of the successful connection of EU registries and CITL to the ITL, our live operations with EU registries have officially started on Wednesday 22 October. As from that date the CDM registry has been able to forward CERs held in temporary holding accounts to their associated EU registries for all cases where the national registry ID was made available by account representatives and where the receiving national registry confirmed their readiness to receive them.
Entities responsible for instructing on forwarding of CERs from the Pending account of the CDM registry to acquiring holding accounts of project participants authorised by an EU country, as stated in the modalities of communication, are encouraged to check whether the corresponding EU national registry is available to receive CERs from the CDM registry and to ensure that the receiving account corresponds to an account within that national registry.
Account representatives of temporary holding accounts that are still expecting to receive CERs in the corresponding national registry are requested to ensure that the national registry account ID has been instructed through the CDM registry online interface (user name and password needed).
16 Oct 08 — Successful connection of the CITL and EU national registries to the ITL
The UN Climate Change secretariat announced on Tuesday 14 October 2008 that it is on schedule to complete the live connection of the UNFCCC International Transaction Log (ITL) with the European Union (EU) Community Independent Transaction Log (CITL) and 26 European Union greenhouse gas emissions trading system (EU ETS) registries. As a result of this, the CDM registry and other Non-EU registries have been switched back to "Operating" mode as from today Thursday 16 October. The CDM registry is therefore now fully operational and able to resume forwarding of CERs as usual.
Please note, however, that the forwarding of CERs from Temporary Holding Accounts (THAs) to the associated EU registries will not take place until all the preparatory work has been completed in coordination with the receiving registries. The exact date when all these CERs will be sent to EU registries will be advised on this page in the next few days.
01 Oct 08 — Connection of the CITL and EU registries to the ITL
The European Commission (EC), Member States and the secretariat of the United Nations Framework Convention on Climate Change (UNFCCC) are currently working on the last preparatory phases of setting up a live connection between the CITL, the UNFCCC International Transaction Log (ITL) and Member State registries. The final connection process between the ITL and CITL will start on 6 October at 8:00 am CEST and is expected to take at least 10 calendar days (see here).
Please note that, as a result of this process, the CDM registry will not be available for forwarding transactions during that time starting on October 7 2008. Although issuance of CERs will still be conducted as usual, ensuing forwarding requests will not be processed until the connection process is finalised.
Once this connection process has been successfully completed, the CDM registry intends to forward all CER units currently held in temporary holding accounts to the national registries they are associated with. All CERs contained in a temporary holding account will be forwarded to the receiving account in the national registry in a single transaction. Specific instructions in this regard are being provided to account representatives via email.
