Celestyal highlighted its experience in adopting biofuels, as the first company to implement it in practice in Greece, during the ESG Shipping Awards 2025 The Conference – Sustainable Shipping: “ESG Leadership in a Time of Uncertainty”, which took place at the Zappeion Mansion in Athens.
As part of the “Shaping Together the Future of Sustainable Shipping” panel, Konstantinos Tsigaras, Managing Director of Coral Marine, referred to Celestyal’s pioneering approach to the use of biofuels, addressing Chrysanthos Chrysanthou, VP Technical of Celestyal, and underlining the company’s role as a model of sustainable shipping in the cruise sector.
Celestyal, implementing its strategic plan, began using biofuels across its entire fleet this year.
The company consumed approximately 2,000 metric tons of B24 in total in 2025, without any technical issues arising.
The shipping industry is facing an increasingly stringent regulatory framework, with the FuelEU Maritime Regulation due to enter into force later this year. Chrysanthou highlighted that compliance costs are already significant and are expected to increase by up to 50% due to compliance with the new regulations by 2026, creating a major challenge, especially for existing ships. He said: “The use of biofuels has emerged as a practical and sustainable transitional solution. Their role becomes even more critical after 2030, when greenhouse gas (GHG) emission intensity limits will become much stricter.
The importance of strategic partnerships to scale up sustainable solutions, such as ours with Coral Marine, has ensured reliable, certified biofuels with full traceability and a secure supply chain.”
Looking ahead, Celestyal plans to:
- Gradually increase blending ratios where feasible.
- Explore advanced biofuels such as HVO and second-generation FAME.
- Integrate energy efficiency measures such as low-friction hull coatings and real-time energy monitoring.
“While regulatory pressure is high and increasing, biofuels have proven to be a reliable, immediate and effective tool in our journey towards compliance and sustainability,” Chrysanthou concluded.
