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 .
Voluntary Cancellation of CERs:
Voluntary cancellation allows project participants who hold certified emission reductions (CERs) in the CDM registry to cancel them on their own behalf or on behalf of third parties. This gives them access to a broader source of demand for CERs in the voluntary market, while making a diverse portfolio of credits available to organizations and individuals wishing to reduce their carbon footprint.

Carbon Trade Exchange (CTX) is our partner
CTX is a wholesale platform for larger scale sales of CERs for businesses, corporations, and institutional buyers. CTX is a global 24/7/365 platform where you can purchase CDM CER cancellations enabled through a linking arrangement which went live in 2017. CTX is a commercial fee-based business designed to support the global voluntary carbon market. You can access membership to CTX via https://ctxglobal.com/

8 December 2020 - Accounts in the UK Kyoto National Registry as of 1 January 2021
As of 1 January 2021, account holders of accounts in the UK Kyoto National Registry will no longer have access to these accounts, and transfers of CERs to the Kyoto National Registry of the UK will no longer be possible. The UK government is procuring a new system to enable account holders to hold and trade Certified Emission Reductions and Emission Reduction Units, which they expect to be operational in Spring 2021.
Type of accounts+ Pending account
Decision 3 CMP/2005/8/Add.1(paragraph 66) states that upon being instructed by the Executive Board to issue CERs for a CDM project activity, the CDM registry administrator, working under the authority of the Executive Board, shall, promptly, issue the specified quantity of CERs into the pending account of the Executive Board in the CDM registry, in accordance with Appendix D.
There is no specific time limit for CERs to remain in the Pending Account of the CDM registry and they are forwarded to the holding account of project participants in accordance with the modalities of communication in place at the time of the request. (See section How to forward CERs to a holding account of a project participant). Project participants should ensure the Share of Proceeds for administrative expenses (SOP Admin) has been paid in full in order to be able to request the forwarding of CERs.
Decision 7 CMP/2005/8/Add.1 paragraph 37defines the resources for work on the clean development mechanism and establishes that the SOP Admin is to be calculated according to the following rule:
(a) USD 0.10 per certified emission reduction issued for the first 15,000 tonnes of CO2 equivalent for which issuance is requested in a given calendar year;
(b) USD 0.20 per certified emission reduction issued for any amount in excess of 15,000 tonnes of CO2 equivalent for which issuance is requested in a given calendar year;
Detailed information related to the issuance of CERs can be found in section “Issuance of CERs”
+ Adaptation fund account
(a) That the share of proceeds to assist developing country Parties that are particularly vulnerable to the adverse effects of climate change to meet the costs of adaptation, as referred to in Article 12, paragraph 8, of the Kyoto Protocol, shall be two per cent of the certified emission reductions issued for a clean development mechanism project activity;
(b) That clean development mechanism project activities in least developed country Parties shall be exempt from the share of proceeds to assist with the costs of adaptation;
The CDM registry has set up a dedicated account for the Adaptation Fund where the two percent of each issuance of CERs is forwarded at the time of the issuance. The work and progress of the Adaptation Fund and its Board can be followed on www.adaptation-fund.org.
Publicly available information on the amount of CERs that are deducted for the Adaptation Fund can be found in section “SOP for the Adaptation Fund” of this site.
+ Temporary holding accounts
Each temporary holding account was associated with one specific holding account in the national registry of the Party that provided the Letter of Authorisation (LOA) for the participation of the entity in a given CDM project activity. As soon as the corresponding national registry was fully connected to the ITL the CDM registry forwarded all the CERs held in the temporary holding account to the associated account in the acquiring national registry in coordination with the counterpart registry. The details of this process was provided to all account representatives once the connection of the national registry has been confirmed by the ITL administrator.
As of 2014, the CDM Registry Administrator has phased out the Temporary holding accounts.
+ Permanent holding accounts
Permanent holding accounts can only receive CERs from the Pending account of the CDM registry and from any CDM project activity in which the account holder is registered as a participant with an authorisation of the same Non-Annex I Party.
Units (CERs, lCERs or tCERs) being held in a permanent holding account can only be forwarded to the holding accounts of entities registered as participants in the CDM project activities that originated those units and with an authorisation (LOA) from an Annex I Party (national registry holding accounts) or non Annex I Party (permanent holding account in the CDM registry).
See section Application for a holding account in the CDM registry for more information on how to open a holding account in the CDM registry. The procedure and requirements are the same for both, temporary holding accounts and permanent holding accounts.
