German Emissions Trading Authority


Transactions are transfers of allowances from one registry account to another. You can initiate internal transactions between two accounts within the same registry, but also external transactions between two accounts in different national registries (for example Germany and Italy). Deleting and surrendering allowances are also transactions. In the Union Registry, transactions are carried out according to certain time specifications. Please pay particular attention to the detailed information on fixed time windows.

The portal also features information about the possibility of listing an additional authorised representative and the list of trusted accounts.

Fixed time window for transactions

Transactions in the Union Registry are generally processed on business days from Mondays to Fridays 10:00 to 16:00 Central European (summer) time (CET/CEST). On Saturdays, Sundays and on public holidays no transactions are initiated.

Although authorised representatives may enter transactions outside this period, the actual initiation occurs only at 10:00 hours CET/CEST of the next business day if the transaction was entered after 10:00 CET/CEST or on 10:00 CET/CEST of the same day, if it was entered before 10:00 CET/CEST. An initiated transaction will be completed only after 26 hours have elapsed. If the time of completion of the transaction, i.e. the time of initiation plus the 26-hour delay lies outside the period specified above (business days 10:00 to 16:00 CET/CEST), then the transaction will be completed on the next business day at 10:00 CET/CEST (exceptions to that rule see below).

Since there is no nationally unified holiday schedule for the German states, the Berlin state holiday schedule is applied to the German part of the Union Registry.

In addition to Saturdays and Sundays, the following days until the end of 2018 are not considered as business days:

  • 01/01/2018 New Year
  • 30/03/2018 Good Friday
  • 02/04/2018 Easter Monday
  • 01/05/2018 May Day
  • 10/05/2018 Ascension
  • 21/05/2018 Whit Monday
  • 03/10/2018 German Unity Day
  • 24/12/2018 Christmas Eve
  • 25/12/2018 Christmas Day
  • 26/12/2018 Boxing Day
  • 31/12/2018 New Year’s Eve


Additional Authorised Representative

Accounts have at least two and a maximum of six authorised representatives. In addition, up to four so-called additional authorised representatives can be appointed (apart from verifier accounts). If at least one additional authorised representative has been set up in an account, a transaction proposed by an authorised representative must be confirmed by an additional authorised representative (four eyes principle). For operator holding accounts and aircraft operator holding accounts, the appointment of additional authorised representatives is optional. If they are appointed, they also need to confirm transactions to accounts that are listed on the Trusted Accounts list. If additional authorised representatives are not nominated, only transactions to accounts on the trusted accounts list (TAL) are possible (cf. paragraph below). For surrendering, exchange, voluntary cancellation of Kyoto certificates and deletion of EU allowances a specific rule exist. For aircraft operator, operator and person holding accounts without additional authorised representatives, a second authorised representative has to approve these transactions.


List of trusted accounts

Operator holding accounts, aircraft operator holding accounts, person holding accounts and trading accounts can contain account specific lists of trusted accounts. Authorised representatives can add new accounts or remove accounts. If an authorised representative modifies this list, it requires confirmation by an additional authorised representative. If no additional authorised representative has been set up, another authorised representative must approve the change.

The addition of a new account to the list of trusted accounts will only take effect after a delay of seven business days. Transactions from operator holding accounts and aircraft operator holding accounts can only be effected to accounts that are included in the Trusted Accounts list, even if additional authorised representatives have been appointed for these accounts. Surrender and exchange transactions as well as voluntary cancellation and deletions are exceptions. Transactions from a trading account to accounts that are not on the trusted accounts list are possible. In this case, an additional authorised representative must have been set up and approve the transaction.

An overview of the transaction rules can be found in the following table:
