THE EUROPEAN COMMISSION,Having regard to the Treaty on the Functioning of the European Union,Having regard to Regulation (EU) 2023/1805 of the European Parliament and of the Council of 13 September 2023 on the use of renewable and low-carbon fuels in maritime transport, and amending Directive 2009/16/EC^note, and in particular Article 19(3) thereof,Whereas:

(1)To increase the consistent use of renewable and low-carbon fuels and substitute sources of energy in maritime transport across the Union, Regulation (EU) 2023/1805 lays down uniform rules imposing a limit on the greenhouse gas intensity of energy used on board a ship arriving at, staying at or departing from ports under the jurisdiction of a Member State, and an obligation to use an on-shore power supply (‘OPS’) or zero-emission technologies at berth in ports under the jurisdiction of a Member State.

(2)To ensure the compliance of monitoring of ships with Regulation (EU) 2023/1805, an electronic database (the ‘FuelEU database’) is to be set up pursuant to that Regulation, which should be used for actions necessary to fulfil the obligations set out in it.

(3)To enable all stakeholders fulfil their obligations set out in Regulation (EU) 2023/1805 in a centralised and harmonised way, the FuelEU database should support: (i) companies in reporting each ships’ energy consumption and emissions; (ii) verifiers in the verification process and issuance of the FuelEU document of compliance; and (iii) the administering authorities in accessing and entering the information needed for their activities.

(4)The objective of the FuelEU database is to significantly alleviate the administrative workload placed on companies, verifiers and other stakeholders. It is built upon the comprehensive network of relevant IT systems, designed to streamline reporting processes within the maritime sector.

(5)The primary foundational structure upon which the FuelEU database is built is THETIS-MRV, which was created to support the implementation of Regulation (EU) 2015/757 of the European Parliament and of the Council^note, with the aim of capitalising on previously submitted data. That strategic approach complies with the ‘reporting only once principle’, fostering synergies between the reporting under Regulations (EU) 2015/757 and (EU) 2023/1805 and ensuring the harmonisation and consistency of information across all operational facets.

(6)In order to be taken into account for the limits set in Article 4 of Regulation (EU) 2023/1805, sustainable marine fuels should be certified in accordance with Article 10 of that Regulation to ensure transparency and mitigate the risk of fraud or erroneous reporting. The Union Database established in accordance with Article 28(2) and (4) of the Directive (EU) 2018/2001 of the European Parliament and of the Council^note could be used to demonstrate the compliance of marine bunker fuels across the whole supply chain. To that end, the FuelEU database environment shall be connected to the Union Database when its scope and functionalities have been adapted accordingly. This will facilitate reporting for companies and support verification activities.

(7)It is necessary to ensure consistency between this Regulation and Commission Implementing Regulation (EU) 2024/2027^note in order to streamline verification activities.

(8)When personal data are processed in the context of the application of this Regulation, Regulation (EU) 2016/679 of the European Parliament and of the Council^note applies. The personal data should be kept in a form which permits the identification of data subjects for no longer than necessary for the purposes for which the data were collected^note.

(9)The European Data Protection Supervisor was consulted in accordance with Article 42(1) of Regulation (EU) 2018/1725 of the European Parliament and of the Council^note and delivered an opinion on 24 July 2025.

(10)The measures provided for in this Regulation are in accordance with the opinion of the Committee on Safe Seas and the Prevention of Pollution from Ships,
