Starting from January 1, 2025, shipowners and operators in European waters are required to collect data on energy usage on board each ship to comply with the FuelEU Maritime regulations. This regulation represents a significant market intervention and sets a new industrial framework for vessels operating in the region. Ships weighing at least 5,000 gross tonnes must reduce the greenhouse gas intensity of their fuels by 80% compared to a 2020 benchmark by 2050, or face penalties. The data collection process must align with the FuelEU Monitoring Plan and be submitted annually to Lloyd’s Register by January 31, 2026, using the Emissions Verifier. The hierarchy of fuels according to Lloyd’s Register places Renewable Fuels of a Non-Biological Origin (RFNBOs) at the top, which are produced by combining green hydrogen with other elements. These fuels offer significant benefits, while fossil fuels face penalties. Criteria for renewable hydrogen production include additionality and temporal/geographic correlation to ensure alignment with new renewable electricity generation. FuelEU also incentivizes compliance by creating a market for surplus reductions. Companies that exceed compliance targets can sell their surplus and potentially generate revenue. This market intervention drives the shift towards lower carbon emissions in the shipping industry, encouraging a sustainable future. The regulation also sets targets for the uptake of RFNBOs in the transport and industry sectors, aiming for at least 1% of total energy supplied to the transport sector to be RFNBOs by 2030, among other goals. The regulation also introduces penalties for non-compliance and outlines the process for data collection and submission to ensure transparency and accountability.
