CDM Registry

3/CMP.1, Annex, Appendix D, paragraph 1 provides 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 (3/CMP.1, Annex, Appendix D, paragraph 1).

The CDM Registry is an electronic database managed by the secretariat, serving as the CDM registry administrator, and into which CERs are issued and from which CERs are forwarded, transferred and cancelled. In November 2005, the Executive Board noted that the full version of the CDM registry had been deployed in the secretariat (EB 22, paragraph 75).

Structure of the CDM registry

The CDM registry is defined as follows:

The CDM registry shall be in the form of a standardized electronic database which contains, inter alia, common data elements relevant to the issuance, holding, transfer and acquisition of CERs. (3/CMP.1, Annex, Appendix D, paragraph 2).

A CER may only exist in one account at a time:

Each CER shall be held in only one account in one registry at a given time (3/CMP.1, Annex, Appendix D, paragraph 4).

The CDM registry must conform to technical standards:

The structure and data formats of the CDM registry are required to conform to technical standards to be adopted by the COP/MOP for the purpose of ensuring the accurate, transparent and efficient exchange of data between national registries, the CDM registry and the international transaction log (3/CMP.1, Annex, Appendix D, paragraphs 2).

The CDM registry has has several accounts:

The CDM registry shall have the following accounts:

  1. One pending account for the Executive Board, into which CERs are issued before being transferred to other accounts
  2. At least one holding account for each Party not included in Annex I hosting a CDM project activity or requesting an account
  3. At least one account for the purpose of cancelling ERUs, CERs, AAUs and RMUs equal to excess CERs issued, as determined by the Executive Board, where the accreditation of a designated operational entity has been withdrawn or suspended
  4. At least one account for the purpose of holding and transferring CERs corresponding to the share of proceeds to cover administrative expenses and to assist in meeting costs of adaptation. This account is not otherwise permitted to acquire CERs (3/CMP.1, Annex, Appendix D, paragraph 3).

Holding Accounts

Each non-Annex I Party providing an entity with written approval to participate in a CDM project activity may request a holding account for that Party in the CDM registry and specify representatives for the account (EB 20, paragraph 69).

The Executive Board has clarified that permanent holding accounts for project participants in the CDM registry shall be marked as being associated with the non-Annex I Party which provided the written approval to participate in the CDM project activity (EB 20, paragraph 69)

Temporary holding accounts in the CDM registry

Pursuant to clarification from the Executive Board, the CDM registry also includes temporary accounts for Annex I Parties, and project participants from such Parties, until national registries for such Parties and entities are operational, for the purposes of receiving CERs forwarded to them from the Executive Board pending account and for transferring such CERs to accounts in national registries (EB 12, paragraph 35(b)).

The Executive Board has clarified that non-Annex I Parties, and project participants from non-Annex I Parties are permitted to transfer CERs, tCERs and lCERs from their holding accounts in the CDM registry to national registries of Annex I Parties (EB 15, paragraph 33).

Temporary holding accounts for project participants in the CDM registry are required to be marked as being associated with the Annex I Party which provided the letter of approval to participate in the CDM project activity. This facilitates the reporting to the DNA of unit holding and transaction data for all accounts associated with each Party (EB 20, paragraph 69).

Account numbers

A unique account number is allocated to each account in the CDM registry:

Each account within the CDM registry shall have a unique account number comprising the following elements:

  1. Party/organization identifier: the Party for which the account is maintained, using the two-letter country code defined by the International Organization for Standardization (ISO 3166), or, in the cases of the pending account and an account for managing the CERs corresponding to the share of proceeds, the Executive Board or another appropriate organization
  2. A unique number: a number unique to that account for the Party or organization for which the account is maintained (3/CMP.1, Annex, Appendix D, paragraph 5).

Role of the CDM Registry Administrator

The COP/MOP charged the Executive Board with the task of identifying a registry administrator to maintain the CDM registry under its authority:

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).

At EB 13, the Executive Board appointed the secretariat to be the CDM registry administrator with responsibility, under the authority of the Executive Board, for implementing and operating the CDM registry (EB 13, paragraph 42).

On instruction by the Executive Board, the CDM registry administrator must issue and forward CERs:

Upon being instructed by the Executive Board to issue CERs for a CDM project activity, the registry administrator shall, in accordance with the transaction procedures set out in decision 13/CMP.1:

  1. Issue the specified quantity of CERs into the pending account of the Executive Board;
  2. Forward the quantity of CERs corresponding to the share of proceeds to cover administrative expenses and to assist in meeting costs of adaptation to the appropriate accounts in the CDM registry for holding and transferring such CERs; and
  3. Forward the remaining CERs to the registry accounts of Project Participants and Parties involved, in accordance with their forwarding request (3/CMP.1, Annex, paragraph 66; 3/CMP.1, Annex, Appendix D, paragraph 6).

At the direction of the Executive Board, the CDM registry administrator is also responsible for making monthly reports available to:

  • the Executive Board, containing aggregate information on unit holdings and transactions, by unit, transaction and account types; and
  • each DNA, containing aggregate information on units holdings and transactions, by unit and transaction types, in relation to the accounts in the CDM registry associated with the Party of the relevant DNA (EB 20, paragraph 72).

Publicly available information

Certain information is required to be publicly available:

The CDM registry is required to make non-confidential information publicly available and provide a publicly accessible user interface through the Internet that allows interested persons to query and view it (3/CMP.1, Annex D, paragraph 9)

This information includes the following account-related information:

The information referred to in paragraph 9 above shall include up-to-date information, for each account number in the registry, on the following:

  1. Account name: the holder of the account
  2. Representative identifier: the representative of the account holder, using the Party/organization identifier (the two-letter country code defined by ISO 3166) and a number unique to that representative for that Party or organization
  3. Representative name and contact information: the full name, mailing address, telephone number, facsimile number and e-mail address of the representative of the account holder (3/CMP.1, Annex, Appendix D, paragraph 10).

The following project-related information is also required to be publicly displayed:

The information referred to in paragraph 9 above shall include the following CDM project activity information, for each project identifier against which the CERs have been issued:

  1. Project name: a unique name for the CDM project activity

  3. the total quantity of CERs transferred and the identity of the acquiring accounts and registries
  4. the total quantity of ERUs, CERs, AAUs and RMUs cancelled in accordance with paragraph 8 above
  5. Current holdings of CERs in each account (3/CMP.1, Annex, Appendix D, paragraph 12).

Additional requirements for afforestation and reforestation (A/R) project activities

The CDM registry will also ensure the accurate accounting of temporary certified emission reductions (tCERs) and long-term certified emission reductions (lCERs) from A/R projects:

The CDM registry established and maintained by the Executive Board shall be used to ensure the accurate accounting of the issuance, holding, transfer, acquisition and cancellation of tCERs and lCERs from afforestation and reforestation project activities under the CDM (5/CMP.1, Annex, Appendix D, paragraph 1).

The provisions relating to the CERs in the CDM registry (described above) also apply to tCERs and lCERs:

All provisions of appendix D to the annex to decision 17/CP.7 that apply to CERs shall also apply to tCERs and lCERs, unless stated otherwise in this appendix (5/CMP.1, Annex, Appendix D, paragraph 2).

The CDM registry contains a specific cancellation account for tCERs and lCERs that have expired while in a holding account (including the Executive Board's pending account) and lCERs that have become ineligible for certification reasons (see below):

In addition to the accounts of the CDM Registry specified above, the CDM registry has a cancellation account to which tCERs and lCERs that have expired in a holding account of the CDM registry, and lCERs that have become ineligible, are transferred (5/CMP.1, Annex D, paragraph 3).

Certification reports must be provided for A/R projects every 5 years.  The CDM registry administrator will record the date of the last certification report and will notify the Executive Board where a certification report has not been provided as required:

The CDM registry administrator will record the date on which each certification report for an afforestation or reforestation project activity under the CDM is received. The CDM registry administrator shall notify the Executive Board of cases where a certification report for an afforestation or reforestation project activity for which lCER are issued, has not been provided within five years of the last certification (5/CMP.1, Annex, Appendix D, paragraph 5).

tCERs and lCERs have an expiry date as part of their serial numbers, and this information is stored in the CDM registry:

Each tCER and lCER shall have an expiry date, specifying day, month and year, as an additional element in its serial number (5/CMP.1, Annex, Appendix D, paragraph 4).

All information referred to in paragraphs 9 to 12 of appendix D to the annex to decision 17/CP.7 tha applies to tCERs and lCERs shall include, as an additional element, the expiry date of each such tCER and lCER (5/CMP.1, Annex, Appendix D, paragraph 6).

The information specified above which is made publicly available equally applies to tCERs and lCERs and includes, as an additional element, the expiry date of each such tCER and lCER (5/CMP.1, Annex D, paragraph 6).
