EMSA Study on Biodiesel-Bunker Fuel Blends as Marine Pollutants
Summary
EMSA has released a study on biodiesel-bunker fuel blends as marine pollutants, conducted jointly by the World Maritime University and Cedre. The study addresses knowledge gaps regarding alternative fuels including FAME, HVO, and Fischer-Tropsch blends, assessing their behaviour as marine pollutants and the effectiveness of response measures in accidental release scenarios. Blends such as B20, B30, and B50 used with Marine Gas Oil or VLSFO are identified as near-term drop-in solutions compatible with existing infrastructure. The research aims to strengthen spill contingency planning and preparedness as the maritime sector transitions to alternative fuels.
“Among the alternative fuels currently being deployed, biodiesel blends based on Fatty Acid Methyl Esters (FAME), Hydrotreated Vegetable Oil (HVO) and Fischer–Tropsch (FT) represent a near-term, "drop-in" solution compatible with existing marine engines and infrastructure.”

What changed
EMSA released a commissioned study on alternative marine fuels examining whether biodiesel blends based on Fatty Acid Methyl Esters (FAME), Hydrotreated Vegetable Oil (HVO), and Fischer-Tropsch (FT) behave as marine pollutants and whether existing spill response measures are adequate for accidental releases. The study was conducted by the World Maritime University and Cedre.
Maritime operators and environmental response authorities should monitor for follow-up guidance as the sector accelerates its transition to alternative fuels. Ports, shipping companies, and contingency planners may need to reassess spill response protocols once the full report findings are published, particularly regarding B20, B30, and B50 blend handling.

New Study on biodiesel-bunker fuel blends as marine pollutants
Date
Published 24.02.2026 Updated 24.02.2026
A new study on blends of biodiesels with conventional marine bunker fuels has been commissioned by EMSA to address critical knowledge gaps concerning alternative fuels as potential marine pollutants, as well as the effectiveness of response measures in the event of accidental releases.
Among the alternative fuels currently being deployed, biodiesel blends based on Fatty Acid Methyl Esters (FAME), Hydrotreated Vegetable Oil (HVO) and Fischer–Tropsch (FT) represent a near-term, “drop-in” solution compatible with existing marine engines and infrastructure. Blends such as B20, B30 and B50, used with Marine Gas Oil (MGO) or Very Low Sulphur Fuel Oil (VLSFO), enable emissions reductions without requiring major technical modifications in ship engines and supply chain.
However, their behaviour as marine pollutants and the suitability of existing response measures in the event of accidental spills are not yet comprehensively documented, highlighting the need for a structured, evidence-based assessment grounded in results from experimental recovery tests.
Conducted jointly by the World Maritime University (WMU) and Cedre, this study aims to support the maritime sector by strengthening spill contingency planning, preparedness, and response as the transition to alternative fuels accelerates.
