Summary

The European Union's FuelEU Maritime Regulation, effective from January 2025, mandates shipping companies to monitor and report energy usage and emissions from vessels over 5,000 gross tonnage. This initiative supports the EU's climate objectives by promoting the adoption of renewable and low-carbon fuels in maritime transport.

Background

The FuelEU Maritime Regulation, formally adopted as Regulation (EU) 2023/1805, is a key aspect of the European Union’s Fit for 55 legislative package, which aims to reduce greenhouse gas (GHG) emissions by at least 55% by 2030 and achieve climate neutrality by 2050. Adopted in September 2023, the regulation targets the maritime sector, which is responsible for roughly 3% of global emissions, by promoting renewable and low-carbon fuels, as well as clean energy technologies like onshore power supply (OPS). The European Commission, supported by the European Maritime Safety Agency (EMSA), oversees its implementation. FuelEU works alongside other EU policies such as the EU Emissions Trading System (EU ETS) and the Monitoring, Reporting, and Verification (MRV) regulations—by setting greenhouse gas (GHG) intensity limits for ship fuels from production to use. This helps ensure consistency with the European Climate Law and the Renewable Energy Directive.

Reporting Requirements

As detailed in the regulations, shipping companies are required to monitor and report detailed data on their vessels' energy usage and associated GHG emissions, including carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O). This encompasses fuel consumption at sea and during berthing, energy received through onshore power supply (OPS), and well-to-wake emission factors for each fuel type. Companies must submit a FuelEU Monitoring Plan by August 31, 2024, outlining their data collection methods. Starting from January 1, 2025, data recording begins, with the first FuelEU Report due to verifiers by January 31, 2026. Verified reports are then submitted to the FuelEU database, and a FuelEU Document of Compliance is issued by June 30 each year, which ships must carry when entering EU ports.

Software solutions for FuelEU compliance include OneOcean Risk Manager's FuelEU module with capabilities such as

  • Voyage simulation & route optimization: to forecast GHG intensity and compliance balances before deployment.

  • Workflow planning and monitoring: to track fuel use, manage balances across parties via pooling, borrowing, and banking strategies, and visualize fleet-level exposure.

  • Automated ingestion of Noon Reports: allowing for integration with Lloyds Register (LR) Emissions Verifier for validation and operating compliance docs

Penalties for Noncompliance

Noncompliance with FuelEU's reporting requirements can result in significant penalties. If a ship exceeds its GHG intensity limit, the company faces a penalty calculated based on the compliance deficit, with fines around €2,400 per tonne of very low sulphur fuel oil (VLSFO) energy equivalent. Failure to meet OPS requirements incurs a penalty of €1.50 per kWh of established electrical power demand at berth. Persistent noncompliance, such as failing to present a valid Document of Compliance for two consecutive periods, can lead to expulsion orders, barring the ship from entering any EU port until obligations are met.
