Aircraft operator holding account

All aircraft operators participating in emissions trading that fall under the Dutch competent authority must have an aircraft operator holding account (AOHA) in the CO2 Registry. This account is necessary in order to receive allocations, enter emissions data and surrender sufficient allowances. An AOHA can also be used to make transfers.

Opening an AOHA

Before you can participate in the EU ETS, you must open an AOHA. The NEa Helpdesk will inform aircraft operators in good time of this procedure. When opening an AOHA, at least two account representatives must be appointed to manage the account. The application must be signed by a person with statutory authority to represent, i.e. somebody who is legally authorised to sign documents (usually a director or member of the Executive Board).


An AOHA for aircraft operators costs nothing. However you may also opt for a Premium Account, which offers additional services. This account type is subject to fees.
