Part of the EU’s wider efforts to accelerate the deployment of renewable energy and reduce greenhouse gas emissions, RED III establishes a framework to encourage the uptake of renewable fuels, including advanced biofuels and renewable fuels of non-biological origin (RFNBOs), across the transport sector. As Member States transpose the directive into national law, the practical implications for the maritime industry are becoming clearer.
While the directive sets common objectives at an EU level, implementation takes place nationally. This means requirements, timelines, and compliance mechanisms may differ between jurisdictions, creating an increasingly complex regulatory environment for companies operating across multiple markets.
At EU level, RED III requires Member States to ensure that renewable energy accounts for at least 14 percent of final energy consumption in the transport sector by 2030. Within this, the directive introduces a progressive mandate for advanced biofuels, produced from circular feedstocks listed under Annex IX Part A, which must reach at least 1 percent in 2025 and 3.5 percent by 2030. To support uptake, advanced biofuels may be counted at twice their energy content towards national targets, creating an important incentive for suppliers to factor these fuels into sourcing and distribution planning.
Recent developments in Spain provide a useful example of how RED III is beginning to take shape in practice. Through the introduction of a new transport decarbonization framework, Spain has established greenhouse gas reduction targets and renewable fuel objectives that will apply from 2027 onwards, including specific provisions for domestic maritime navigation. Similar developments are expected across Europe as Member States continue to implement the directive.
“The direction of travel is clear: renewable fuels are moving from an alternative option to an increasingly important component of long-term maritime energy strategies,” said Maria Angeles Lopez, Peninsula’s Decarbonization Manager.
For maritime stakeholders, the significance extends beyond compliance. As renewable fuels become more closely linked to national decarbonization targets, factors such as fuel availability, sustainability certification, and greenhouse gas performance are likely to play a growing role in operational and commercial decision-making.
Many regulatory frameworks emerging under RED III also introduce mechanisms intended to support compliance and encourage investment in lower-carbon fuels. While details vary by country, these developments reinforce the growing importance of understanding not only the characteristics of a fuel, but also how it is recognized within the relevant regulatory framework.
RED III should also be considered alongside FuelEU Maritime, which creates demand-side pressure by requiring vessels over 5,000 GT to progressively reduce the yearly average greenhouse gas intensity of the energy used on board. The regulation begins with a 2 percent reduction requirement in 2025, rising to 6 percent by 2030 and scaling up to 80 percent by 2050. Together, the two frameworks are expected to reinforce demand for advanced biofuels and RFNBOs, while FuelEU Maritime’s multiplier for RFNBOs until the end of 2033 further supports early market development.
However, the regulatory value of renewable fuels depends on more than physical availability. To be recognized under the framework, biofuels must meet strict sustainability and greenhouse gas savings criteria, including a greenhouse gas emissions savings threshold of at least 65 percent for installations that started operation after January 2021. RFNBOs must deliver emissions savings of at least 70 percent. Economic operators are also legally required to maintain traceability through a mass balance system, ensuring that the sustainable characteristics of the fuel remain assigned to the physical mixture. All sustainability data must be independently audited and certified under voluntary schemes recognized by the European Commission. Fuels that do not meet these certification and emissions savings requirements may be treated as equivalent to the least favorable fossil fuel pathway, creating potential compliance deficits and financial penalties.
For organizations operating across Europe, staying informed about national implementation will be just as important as understanding the directive itself. The pace of change is not uniform, and differences between jurisdictions may influence fuel strategies, compliance planning, and customer requirements.
As RED III continues to gather momentum across Europe, maritime businesses will need to navigate an evolving regulatory landscape while balancing operational realities and decarbonization ambitions. Companies that remain informed and adaptable will be best placed to respond to changing requirements and take advantage of emerging opportunities in the renewable fuels market.
At Peninsula, we continue to monitor regulatory developments across our markets, helping customers understand an evolving compliance landscape and explore practical pathways towards decarbonization.
