EU Emissions Trading 1 for Maritime Transport

Last update 22.03.2024

Since 2024, maritime transport has been part of the European Emissions Trading System (EU ETS 1). The obligations under the EU MRV Maritime Transport Regulation remain in place and form the legal basis for the monitoring and reporting obligations of shipping companies.

Guidelines for the preparation of monitoring plans in maritime transport

Our guideline for the preparation of monitoring plans (available in German only) provides you with an overview of the individual procedural steps for the preparation as well as the content and technical requirements for the monitoring of greenhouse gas emissions in maritime transport.

Geographic Scope

Starting in 2024, all countries in the European Economic Area (EEA) engaging in the EU ETS 1 for Maritime transport are required to surrender emission allowances for greenhouse gas emissions generated during a journey within the EEA or on journeys into or out of the EEA (see Article 3ga Directive 2003/87/EC).

The emissions caused are considered differently with regard to the surrender obligation:

  • 50 per cent of emissions for journeys where one port of call is outside the EEA and the other is within the EEA.
  • 100 per cent of emissions for journeys within the EEA where both ports of call are located in an EU ETS 1 Member State.
  • 100 per cent of emissions at berths within the EEA.

Port of call

Article 3(z) Directive 2003/87/EC identifies a port as a port of call where a ship stops to load or unload cargo, to embark or disembark passengers, or where an offshore vessel stops for the purpose of changing crews. Article 3(z) Directive 2003/87/EC excludes the following stops which are not covered by the term ‘port of call’ within the meaning of EU ETS 1:

  • stays exclusively for refuelling/bunkering;
  • stops for procurement of supplies;
  • stays for the sole purpose of changing crews (except for offshore vessels);
  • stays in dry docks or for carrying out repairs to the ship and/or its equipment;
  • stays in a harbour because the ship needs assistance or is in distress at sea;
  • transhipments from ship to ship outside of harbours;
  • stays exclusively for the purpose of seeking shelter from bad weather or those necessitated by search and rescue operations;
  • stays of container ships in neighbouring container handling ports listed in the implementing act pursuant to Article 3ga(2) of the Directive 2003/87/EC. The purpose of this is to prevent evasive manoeuvres to minimise surrender obligations by making stopovers prior to entering the European Economic Area. The ports of ‘East Port Said’ in Egypt and ‘Tanger Med’ in Morocco have been listed for the start of maritime emissions trading in 2024. The implementing act will be regularly evaluated to counteract further evasive manoeuvres.

FAQs on geographic scope

  • A neighbouring container handling port is a port that meets the following criteria (cf. Article 3 ga(2) Directive 2003/87/EC):

    • the proportion of container transhipment has exceeded 65 per cent of that port's total container traffic in the last twelve months,
    • the port is located less than 300 nautical miles from the nearest EEA port,
    • transhipment of containers takes place exclusively from ship to ship.

    The purpose of designating such ports is to prevent avoidance manoeuvres to reduce the surrender obligation by making stopovers before entering the European Economic Area. For this reason, container ports in third countries that apply an emissions trading system comparable to the European one are not included in the above-mentioned container handling ports. The ports of ‘East Port Said’ in Egypt and ‘Tanger Med’ in Morocco were identified in a corresponding regulation for the start of emissions trading in the maritime transport sector.

Ship Types and Greenhouse Gases Covered

Ship types

The size of a ship is indicated by the gross tonnage (GT) from a length of 24 metres.

  • The Directive 2003/87/EC’s scope initially covers large ships such as cargo and passenger ships with a GT of 5,000 or more.
  • Large offshore vessels with a GT of 5,000 or more will follow from 2027.

The European Commission will prepare a report by the end of 2026 analysing the feasibility and economic, environmental and social impacts of including small ships in the Directive to extend the scope to small ships of 400 GT or more.

The EU MRV Maritime Transport Regulation already covers smaller general cargo and offshore vessels with a GT of 400 or more from 01/01/2025 (see link below MRV obligations). Warships, fishing vessels, naval auxiliaries, simple wooden vessels, non-powered vessels and government ships for non-commercial purposes are excluded from the Directive 2003/87/EC scope, as is inland navigation.

Obligated Parties in Maritime Transport

Declaration for compliance with EU ETS 1 obligations

Greenhouse gas emissions caused during journeys or calling in at ports within the EEA or during journeys to or from the EEA are the shipping company’s responsibility.

According to Article 3w) Directive 2003/87/EC, the term ‘shipping company’ means the shipowner or any other organisation or person (for example the manager or the bareboat charterer) who has assumed responsibility from the shipowner for operating the ship. The same person has also agreed to assume all obligations and responsibilities arising from the International Management Code for the Safe Operation of Ships and for Pollution Prevention as set out in Annex I to Regulation (EC) No 336/2006.

This especially includes ISM companies or ISM managers. If there is no contractual agreement or the authorisation has not been properly proven, the ship owner remains the obligated party. In the first instance and in case of doubt, the shipowner is therefore the obligated party. The shipping company must surrender allowances for the Emissions generated by all ships operated under their responsibility that fall within the above-mentioned scope pursuant to the statutory regulations.

If the shipowner remains the responsible shipping company within the meaning of maritime emissions trading, a list of all ships for which the shipowner has assumed responsibility for the EU ETS 1 obligations must be submitted to DEHSt. Please use the template declaration for compliance with EU ETS 1 obligations

FAQs on obligated parties

  • Shipping companies must submit a verified emissions report for the entire previous reporting year for each ship under their responsibility by 31 March of the following year. This applies regardless of company changes and regardless of who is required to surrender allowances for these emissions. The emissions report must cover the entire reporting year. For the year in which the ship was under the responsibility of another company, the report is based on the partial emissions report of this company. For the partial emissions report, see also FAQ 33.

Mandating of the ISM Managers

Mandate for compliance with EU ETS 1 obligations

A shipowner can transfer responsibility for the operation of their ships and the compliance with EU ETS 1 obligations to another organisation or person by a mandate. The basic requirement for this is that the mandated person or organisation can represent the shipowner as an ISM manager. It is therefore necessary for the ISM manager to hold a "Document of Compliance" (ISM-DOC), i.e. to be ISM-certified. If this is the case, then this ISM manager can assume responsibility for the compliance with the EU ETS 1 obligations from the shipowner. Following proper authorisation (mandate), the ISM manager is thus deemed to be a shipping company within the meaning of the Directive 2003/87/EC (cf. Article (3)(w)) Directive 2003/87/EC). The content requirements for the mandate have been defined by the EU Commission (cf. Article (1)(3) Implementing Regulation (EU) 2023/2599). Please use the mandate template linked below. The mandate must be (electronically) signed by both the shipowner and the ISM manager and submitted to the verifiers together with the monitoring plan and to the competent authority when applying to open the MOHA. If the mandate is not written in German or English, a certified German or English translation must be submitted.

If an ISM manager is to assume responsibility for complying with the EU ETS 1 obligations of various ship owners (e.g. single-ship companies), the ISM manager must be authorised by each owner through a corresponding mandate. The ISM manager then assumes responsibility as a shipping company for the compliance with the EU ETS 1 obligations for all vessels under his responsibility, even if they belong to different owners. The ISM manager must then apply for the opening of a ship operator holding account (MOHA) covering all vessels for which they have assumed the compliance with the EU ETS 1 obligations.

If the ISM manager wishes to be released from the assumed ETS obligations, both parties must formally revoke the mandate in writing and the corresponding document must be sent to DEHSt for review. Upon revocation of the mandate, a change of shipping company takes place necessitating the submission of a partial emission report (see FAQ). The same applies to mandates that take effect after 01/01/2024. In this case, a change of company also takes place during the reporting period. ISM managers who have not been expressly authorised by the owner to assume the EU ETS 1 obligations through a mandate are not considered responsible parties within the meaning of the Directive 2003/87/EC and are therefore not sanctioned in the event of non-compliance with the EU ETS 1 obligations. In this case, the responsibility to comply with the ETS obligations remains with the owner.

Responsibility for complying with the MRV and EU ETS 1 obligations must be assumed by the same organisation or person (see Recital (6) of Implementing Regulation (EU) 2023/2599).

FAQs on mandating

  • The shipping company that operated the ships is responsible for surrendering a number of allowances corresponding to the emissions produced by their ships during the relevant period (see Article 11a(1) EU MRV Maritime Transport Regulation).

    Example: If a ship changes from company A to company B on 01/04/2025, company A must surrender a number of allowances in 2026 that corresponds to the emissions produced by this ship from 01/01/2025 to 01/04/2025. Company B must then surrender a number of allowances in 2026 that corresponds to the emissions produced by this ship from 02/04/2025 to 31/12/2025.

Monitoring

Shipping companies covered by the EU ETS 1 for maritime transport must monitor their Emissions based on an approved monitoring plan.

Shipping companies that were operating within the scope of the EU MRV Maritime Transport Regulation before 01/01/2024 must submit a monitoring plan (revised if necessary) to the competent administrative authority by 01/04/2024 for each of their ships falling within the scope. In this plan, they must specify the methods by which CO2, CH4 and N2O emissions and other relevant information will be monitored and reported. The plan must be approved by the competent administrative authority by 06/06/2025.

For ships newly falling within the scope of the EU MRV Maritime Transport Regulation after 01/01/2024, the monitoring plans must be submitted immediately, but no later than three months after the first call at an EEA port. Authorisation will be granted within the first four months after the first call at an EEA port. The monitoring plans must have been verified by a verifier to ensure compliance with Article 6 and 7 of the EU MRV Maritime Transport Regulation before submission to the competent authority.

tasks and obligations for shipping companies, verifiers and authorities

Reporting

From 2025, shipping companies must submit a verified Emissions report (EmB) at ship level to the competent administrative authority, the flag state authority of the competent Member State if applicable and the European Commission by 31/03 of each year.

In addition, from 2025, shipping companies must submit their aggregated emissions data at company level to the competent administrative authority as a basis for determining the surrender obligation. The same deadline applies here as for the emissions report at ship level.

Account suspension and imposition of fines are provided for to enforce reporting obligations in the event of violations.

tasks and obligations for shipping companies, verifiers and authorities

FAQs on reporting

  • In the event that a ship changes ownership to another shipping company during a reporting year, the former shipping company is obliged to submit a verified ship-related (partial) emissions report to their competent authority, the flag state and the European Commission immediately and, at the latest, no later than three months after the ownership change has been completed. The report should cover the period in which the ship was under the responsibility of the former shipping company. The new shipping company is then obliged to submit a verified total emissions report for the reporting year of the change, including the partial report, by 31 March of the year following the change.

    The former shipping company is subject to surrender obligations for the emissions produced by the ship up to the point in the year at which the change took place. The new shipping company must then surrender the corresponding allowances for the emissions produced by the ship in the year following the ownership change. For example, if a ship changes from company A to company B on 01/04/2025, company A must surrender allowances in 2026 for the emissions produced by the ship from 01/01 to 01/04/2025. Company B must surrender allowances in 2026 for the emissions produced by the ship from 02/04/2025 to 31/12/2025.

  • The reporting year is the period of a calendar year from 01/01/ to 31/12/.

  • The reporting year is the period of a calendar year from 1 January to 31 December. Therefore, journeys that start and end in two different calendar years require the corresponding data to be recorded in the respective reporting periods. For example, if a ship's journey starts on 22/12/2024 and ends on 08/01/2025, the emissions monitored by the shipping company in question from 22/12 to 31/12/2024 will be reported in the 2024 emissions report. The emissions produced from 01/01 to 08/01/2025 will then be included in the 2025 emissions report.

  • If a shipping company violates their reporting obligations under the EU MRV Maritime Transport Regulation, their account may be suspended and a fine imposed.

    Account suspension

    If a shipping company fails to meet their reporting obligations, the competent administrative authority will suspend the account. Details on account suspension are regulated in the Greenhouse Gas Emissions Trading Act, which is currently being revised.

    Imposition of fines

    If an emissions report, a monitoring plan, an amended monitoring plan or an adjusted monitoring plan is not submitted to the competent authorities, or is not submitted correctly, completely or on time, the shipping company is violating administrative rules and may be fined. Details of offences that can result in fines are regulated in the Greenhouse Gas Emissions Trading Act, which is currently being revised.

  • Yes, shipping companies must continue to report their greenhouse gas emissions through the existing THETIS MRV platform. This will be updated to reflect the changes made by the revised EU MRV Maritime Transport Regulation and Directive 2003/87/EC.

  • Emissions from ships are verified by verifiers accredited for the EU ETS 1 and the EU MRV Maritime Transport Regulation. Shipping companies can choose the verifier regardless of the ship’s flag or the locations where the company is based or where the verifier is based. In principle, a company can have different verifiers for each of their ships, and different verifiers can verify the ship's emissions report and the company-level report.

Surrender Obligation

The number of emission allowances a shipping company must surrender for the Emissions caused by their ships is determined within the report on aggregated emissions data at company level. Annex II Part C of the EU MRV Maritime Transport Regulation contains a calculation table including all additional calculation steps that correspond to the scope defined in Directive 2003/87/EC and the transitional arrangements and exemptions granted such as:

  • Surrender-reducing offsetting for the use of biogenic fuels or biogenic proportions in fuels, "renewable fuels of non-biological origin" (RFNBO) and "recycled carbon fuels" (RCF)
  • 50 per cent reduced surrender obligation for journeys between ports of call in Member States and ports of call outside the jurisdiction of Member States and vice versa
  • Surrender-reducing offsetting of CCU (Carbon Capture and Utilisation) or Carbon Dioxide Capture and Storage (CCS) approaches pursuant to Article 12(3a) and (3b) Directive 2003/87/EC
  • Surrender-reducing inclusion of ice-class ships by 5 per cent by the end of 2030
  • The reduced surrender obligation in percentage terms in the first two years of maritime emissions trading: allowances have to be surrendered for only 40 per cent of verified emissions for 2024 and for only 70 per cent of verified emissions for 2025.



Increase in the EU ETS maritime transport surrender obligation
EU emissions trading in maritime transport: increase in the surrender obligation


Emission allowances for the emissions caused in the previous year must be surrendered to the Union Registry by 30/09 of each year.

Various Penalties are specified in the event of violations of the surrender obligation:

  • publication of the names of the shipping companies concerned
  • determination of a penalty payment with a subsequent surrender obligation
  • expulsion/determination regulation
  • imposition of fines.

FAQs on surrender obligation

  • The shipping company that operated the ships is responsible for surrendering a number of allowances corresponding to the emissions produced by their ships during the relevant period (see Article 11a(1) EU MRV Maritime Transport Regulation).

    Example: If a ship changes from company A to company B on 01/04/2025, company A must surrender a number of allowances in 2026 that corresponds to the emissions produced by this ship from 01/01/2025 to 01/04/2025. Company B must then surrender a number of allowances in 2026 that corresponds to the emissions produced by this ship from 02/04/2025 to 31/12/2025.

  • No, there are no specific emission allowances for the maritime transport sector. Shipping companies can and must purchase general emission allowances (EUAs) which are also used by industry, the energy sector and aircraft operators.

  • Shipping company A cannot surrender emission allowances for shipping company B from their registry account A (maritime operator holding account). The account holder of the maritime operator holding account is generally the obligated party. They are free to use the support of third parties to take on administrative tasks such as opening an account or performing transactions in the registry. For this purpose, authorised representatives who are not employees of the obligated party can be added when an account is opened or changed. Both account ownership and responsibility for the fulfilment of the surrender obligations under Directive 2003/87/EC remain with the shipping company.

  • Biomass and renewable fuels of non-biological origin (RFNBOs) and recycled carbon fuels (RCFs) are to be treated equally in the various ETS sectors. Therefore, compliance obligations for the use of such fuels are the same in all sectors covered by the EU ETS 1 including aviation and shipping.

    Currently, emissions resulting from the combustion of sustainable biofuels that fulfil the sustainability criteria of the Renewable Energy Directive have an emission factor of zero within the EU ETS 1. A specific regulation dealing with RFNBOs and RCFs will be specified by an implementing act.

Aquisition of Allowances

Allowances can be purchased on the Primary Market via auctions on the European Energy Exchange (EEX). Allowances can be sold bilaterally or via various derivatives provided by financial institutions on the Secondary Market.

A shipping company must open a trading account or a maritime operator holding account in the Union Registry to acquire allowances.

Competent Administrative Authority

On 30/01/2024, the European Commission adopted the Implementing Decision (EU) 2024/411. This sets out the allocation list for all shipping companies that fall within the scope of EU ETS 1 from 01/01/2024.  The decision designates the companies to responsible authorities in accordance with Article 3gf (2) of Directive 2003/87/EC. The decision is effective across all EU Member States, assigning all relevant shipping companies to a national authority. The list will be updated every two or four years. We, the German Emissions Trading Authority, are the competent administrative authority in Germany.
