Target Audience:
Shipping companies operating within or making voyages to European Economic Area (EEA) ports must report annual emissions under EU ETS requirements.
Key Messages:
1. Stay compliant with EU ETS regulations by ensuring your shipping company has an Administering Authority in place.
2. The European Commission has published Implementing Decision 2024/411 attributing Administering Authorities based on THETIS-MRV and SafeSeaNet information.
3. Non-EU registered shipping companies can determine their Administering Authority based on the Member State of a first voyage or equal highest port calls in the scope of ETS.
4. Keep updated with reattributions every two years for EU-registered companies and every four years for non-registered companies.
5. Administering Authorities will remain constant unless updated based on the specified cycles.
Future updating
- Before 1 February 2026 (and every two years afterward), to reattribute shipping companies registered in a Member State to another AA if they changed the EU Member State of registration, or to include shipping companies which fell within the scope of the EU ETS for the first time.
- Before 1 February 2028 (and every four years afterward), to reattribute shipping companies that are not registered in a Member State to another AA where the shipping company performed the greatest estimated number of port calls in the preceding four monitoring years.
Administering Authorities will remain as per the most recently published list, irrespective of changes in the shipping company’s activities or registration. Only when the AA list is updated (as per the indicated cycles above) will the AA responsible for a shipping company change.
Who will be affected by EU ETS:
- As appropriate and where not already addressed, decide if responsibility for compliance with EU ETS will remain with the shipowner or be contractually mandated to the ISM DOC company.
- Shipping companies responsible for compliance with EU ETS should refer to the list of attributed AAs to determine their relevant AA.
- Where responsibility has been contractually mandated from the shipowner to the ISM company, the contractual mandate must be shared with the relevant AA.
- Shipping companies must inform their AA of the list of ships they have assumed responsibility for EU ETS compliance. Should the list of ships change, it is the shipowner’s responsibility to inform their AA.
- As per Delegated Regulation (EU) 2023/2904 Article 15a, the shipping company with responsibility for EU ETS compliance must open a Maritime Operators Holding Account (MOHA) in the Union Registry:
- Within 40 working days for shipping companies, which are included in the published list of assigned AA (Regulation 2024/411).
Within 65 working days of the first port of call falling within the scope of the ETS Directive for shipping companies not listed in Regulation 2024/411
