In this section you will find information regarding the topic "Accounts" in the Union Registry. We provide assistance concerning account opening and the different types of accounts. We also explain the different account identifiers and inform you about necessary applications e.g. for an operator change or an account closure.

Registering of authorised representatives

There are two different types of authorised representatives:

  • Authorised representatives who can execute and arrange transactions
  • Additional authorised representatives whose appointment is optional

You must appoint at least two authorised representatives when applying for an account. The number of authorised representatives is limited to six. Exceptions are verifier accounts where only one authorised representative may be appointed.

In addition, account holders may appoint up to four so-called additional authorised representatives. If at least one additional authorised representative has been confirmed with an account, a transaction proposed by an authorised representative must be confirmed by an additional authorised representative (four eyes principle). Further information on the sometimes rather complex transaction rules of the Union Registry can be found in the Transactions section.

You require the user ID (URID) of the authorised representatives when appointing them. This is why anyone appointed for the first time as an authorised representative or additional authorised representatives must initially perform the following steps 1 and 2:


Account Opening

Accounts to be administered by Germany must be opened in the German section of the Union Registry. The following account types can be selected when applying for an account:

  • Operator holding account
  • Aircraft operator holding account
  • Person holding account
  • Trading account
  • Verifier account

If the installation subject to emissions trading is located in Germany or if the aircraft operator is assigned to Germany through the Administering Member States list, the operator holding account or aircraft operator holding account must be opened in the German section of the Union Registry.

The user manual of the Union Registry is only available to registered authorised representatives. You will receive a link to the manual after your initial registration.


Step 1: Registering at the EU Login Authentication Service

New authorised representatives must first register through the EU Login authentication service.

To register at the Union Registry, you require:

  • Username and password (freely selected)
  • An email address (actual identifier)
  • Mobile telephone number (for the two-factor-authentication at the Union Registry)

Step 2: Creating a user ID (URID) in the Union Registry

After successfully registering online at EU Login, the authorised representatives must create a user ID (URID) in the Union Registry. You are therefore requested to enter personal details when registering with the Union Registry for the first time. The system subsequently assigns the individual URID.

If you have been appointed as an authorised representative for the first time, the German Emissions Trading Authority (DEHSt) will verify your identity using the supporting documents that must be submitted in writing along with the account application (Step 4). As soon as we have confirmed you as an authorised representative, we will send you an enrolment key (Step 5) by mail to complete the account opening process, which you must enter to fully activate your access.

Only users with a German URID can be appointed as authorised representatives in the section of the Union Registry administered by Germany; these URIDs always begin with DE.

The following instructions expand on the procedure described in Steps 1 and 2 in more detail and with numerous screenshots (we are currently revising the documents and will provide them as soon as possible in an updated form).

Step 3: Applying for an account

There are different account types in the Union Registry. Operators require an operator holding account while aircraft operators need a corresponding aircraft operator holding account. Any natural person or legal entity may also open person holding accounts or trading accounts. The difference between account types lies primarily in the way transactions are executed. For further explanation, please refer to the Transactions section.

Please note: before filling in the online application form, take time to familiarise yourself with the procedure described in the following documents. Since the online form of the Union Registry does not allow any interim storage, please start filling in the form only when you have the complete data at hand.

Operators of an installation subject to emissions trading require an operator holding account in the German section of the Union Registry. This account is used to prove that the installation complies with the EU ETS obligations.

Aircraft operators assigned to Germany by the Administering Member States list require an aircraft operator account in the German section of the Union Registry. This account is used to prove that the aircraft operator complies with the EU ETS obligations.

Person holding accounts can be opened in the Kyoto section as well as in the EU-ETS section of the Union Registry. For example, accounts in the Kyoto section are required if CERs from the CDM registry are issued to project participants. According to Kyoto regulations, this payout of certificates can only be carried out to accounts in national Kyoto registries that have approved the CDM project. Accounts in the Kyoto section cannot hold any European allowances (EUA, aEUA, see Allowances and Kyoto credits).

Unlike person holding accounts, trading accounts offer the possibility to carry out transactions without the 26-hour transaction delay and even to accounts that are not on the trusted accounts list. For further explanations, please refer to Transactions.

Verifier accounts are exclusively used for access by verifiers to the Union Registry. These accounts cannot hold any allowances or Kyoto credits. Only accredited verifiers can open an account in the German section of the Union Registry. Operators or aircraft operators must assign a verifier to their account. This assignment must be subsequently confirmed by the verifier or its authorised representative in the Union Registry. Only after this has been done can the verifier enter or confirm the verified emissions in the corresponding operator holding and aircraft operator holding accounts in the Union Registry.

Step 4: Submitting the account application and supporting documents

To finalise the online application for the account, the Union Registry will send a PDF file containing the details of the application to the specified e-mail addresses of the authorised representatives.

This file must be returned to us electronically together with the required evidence via the Virtual Post Office (VPS).

Alternatively, the PDF file for person holding accounts and trading accounts can be sent to us by mail. Please note that the authorised representatives are legally obliged to sign the printout..

Step 5: Entering the enrolment key

After the authorised representatives have been appointed and we have all the completed application documents, we will check the identity of the authorised representatives. If this verification is successful, the authorised representatives will be sent an enrolment key by mail which they must enter when logging into the Union Registry.

The authorised representatives will then have access to the fully activated account.

Authenticating the identity and entering the verification key are only required for the first activation of the URID by the user. Therefore, if the user is appointed as an authorised representative for further accounts, the same URID used for the online application should be utilised. The URID as well as the enrolment key are only valid for the territory of a Member State. In contrast, access through EU LOGIN can also be used in those sections of the Union Registry administered by other Member States.

After logging in, the enrolment key can be entered directly on the homepage of the Union Registry via the "Enter your enrolment key" link.

  • To log in to the Union Registry, you must always choose the path from the Union Registry homepage.
  • On EU Login homepage you can update your EU Login data.

Annual confirmation of the account information

According to the Registry Regulation (EU) 389/2013 Article 25 Paragraph 1 account holders have to confirm that the information on their accounts is complete, up-to-date, accurate and true by 31/12/. This applies to EU-100 type accounts as well as to DE-121 type accounts and thus to operators, aircraft operator and personal holding accounts, trading accounts and verifier accounts.

Please use the following form for the confirmation. Provided that the account holder matches, the form can be used for multiple accounts at once. Confirmations for the present year will be accepted from 01/10/ until 31/12/.

Accounts opened after 01/10/ have to be confirmed in the following year.Please be aware that missing confirmations can result in the suspension of access to the account.


Changing Operators

If the installation operator is changed, the previous and new operators must immediately advise the German Emissions Trading Authority (DEHSt) about the transition and submit the following documents:

  • A letter informing DEHSt of the change in operators
  • A joint takeover statement signed by the authorised representatives of the former and new operator
  • A current Commercial Registry extract for the new operator if this is not already available to DEHSt
  • A completed "Data collection form for the re-registration of an operator holding account for change of operators" in accordance with the instructions for completing and submitting the form

On examining the submitted documents, DEHSt will create, where appropriate, a personal holding account for the previous operator to which the allowances in his account will be transferred. Finally, the operator holding account will be re-registered to the new operator.

When changing operators, the operators are required to manage the transfer of emission allowances which have already been allocated amongst each other, and make the appropriate arrangements in the Emissions Trading Registry.

The new operator receives the future allocations and is responsible for fulfilling surrender obligations.


Account Identifiers

The system of account identifiers in the Union Registry differs from that of other Kyoto registries outside of the Union Registry. In the Union Registry, account identifiers in the EU ETS section and in the Kyoto section consist of five elements:

(1) Country code - (2) Account type - (3) Account number - (4) Commitment period or Holding account - (5) Security code.

For example: EU-100-1234567890-0-35

  • EU stands for European Union
  • 100 indicates holding accounts in the EU ETS context and the account type National Account in the context of Kyoto
  • 1234567890 is the actual account number
  • 0 is the identification of a holding account and
  • 35 is the security code

All (holding) accounts in the Union Registry are of account type 100, so that it cannot be seen from the second element whether, in the EU-ETS context, it is a national, operator holding, person holding, aircraft operator holding or trading account. An exception is the verifier accounts in which no allowances and certificates can be held – they are of account type 0 and therefore start with EU-0 ...

Account identification codes of the national Kyoto registries outside of the Union Registry consist of only four elements:

(1) Country code - (2) Account type - (3) Account number - (4) Commitment period or Holding account. They lack the fifth element, the security code.

The following figure illustrates the different account systems inside and outside the Union Registry.

These different systems may lead to problems for transactions between accounts of the Union Registry and accounts outside of the Union Registry. Please take note of the following information, should you have transactions with accounts outside the Union Registry.

The security code cannot be submitted in a transaction from an account of a Kyoto-registry outside the Union Registry to an account inside the Union Registry. With transactions in the opposite direction – i.e. a transaction from within the Union Registry to a Kyoto registry outside Europe – the security code field displayed in the Union Registry must remain empty because accounts in a Kyoto registry outside the Union Registry do not contain this element. The following examples illustrate the various possibilities.


Account fee

The account fee for person holding accounts and trading accounts is 400 Euro for the current trading period (2013-2020). There are no additional account fees. Transactions (including transactions to accounts in other Registries) are free of charge.


Account Closure

The closure of a person holding account or trading account may be applied for in the Union Registry online at any time, provided there are no allowances in the account.

For this purpose, the authorised representative should click on <Close> under <Actions> in the account view in the right-hand column of the account to be closed and then on <Confirm account closure>.

An application number (identifier) will be displayed which you should enter in this form along with the account identifier and the name of the account holder.

Please return the completed account closure application

  • via the Virtual Post Office (VPS) to DEHSt
  • or send us your printed application signed by the authorised representatives of the account holder by mail

The account closure will only take effect when the DEHSt Registry Administration has confirmed it. The authorised representatives will be told about the completed account closure by the Union Registry via an email which will include the application number (identifier).

Additional authorised representatives cannot apply for an account closure.
