MPA Singapore is continuing its commitment to becoming a global leader in sustainable shipping with the announcement of new regulations for bunker tankers that will further support the adoption of biofuels in maritime operations. Effective from 7 March 2025, the Maritime and Port Authority of Singapore (MPA) will allow Singapore-registered conventional bunker tankers to carry and deliver biofuel blends of up to B30 (30% biofuel content) without the need for separate approval from the authority.
This marks a significant step in facilitating the use of cleaner, renewable energy sources in the maritime industry, a sector under increasing pressure to reduce its carbon footprint.
Key Highlights of the New Regulations
- Biofuel Blends Up to B30 Allowed
From 7 March 2025, conventional bunker tankers registered in Singapore will be permitted to carry and deliver biofuel blends of up to B30 (30% biofuel content), significantly raising the permissible limit from the current B25 (25% biofuel). This change will make it easier for bunker suppliers and operators to integrate biofuels into their fuel offerings without requiring additional approvals from the MPA, streamlining the supply chain for sustainable fuels. - Supporting the Decarbonization of the Maritime Industry
This move aligns with Singapore’s broader commitment to supporting the maritime industry’s decarbonization efforts. As one of the world’s busiest ports and a major hub for global shipping, Singapore plays a crucial role in driving the transition to greener shipping fuels. The increased uptake of biofuels is seen as a key solution to reducing emissions from the shipping sector, which is responsible for a significant share of global CO2 emissions. - Approval Process for Higher Biofuel Blends
While blends of up to B30 will no longer require separate MPA approval, for biofuels exceeding B30, or those not listed in the International Bulk Chemical (IBC) Code or the MEPC.2/Circ.27 (Annex 11), bunker suppliers and operators must seek approval from the MPA’s Standards & Investigation – Marine Fuels (SIMF) department. This will ensure that the proper technical and safety measures are in place for higher-concentration biofuel deliveries, with ongoing pilots for biofuels up to B100 currently being tested. - Implementation of International Maritime Organization (IMO) Guidelines
The new MPA regulations are in line with international efforts to standardize biofuel use in shipping. Ahead of the 83rd session of the IMO’s Marine Environment Protection Committee (MEPC) in April 2025, MPA has adopted the draft guidelines on the carriage of biofuel blends, which will allow conventional bunker ships certified under MARPOL Annex I to transport biofuel blends of up to 30%. These international guidelines are a critical step toward ensuring safe and efficient biofuel usage across the global fleet. - Bunker Suppliers’ and Operators’ Responsibility
For biofuel blends up to B30, bunker suppliers and craft operators must still conduct comprehensive technical and operational risk assessments and mutually agree on terms between the buyer and seller before delivery. This ensures that all parties involved in the bunkering process are fully aware of the potential risks and are prepared to handle the biofuels safely. - Pilots for Biofuels Above B30
Bunker suppliers will also be able to engage in pilot projects for biofuels up to B100 as part of ongoing testing to assess the viability and effectiveness of higher biofuel concentrations. These trials will provide valuable insights into the operational challenges and safety considerations of using biofuels at even higher concentrations.
Impact on the Bunkering Industry
With these updated regulations, Singapore is positioning itself as a leader in sustainable marine fuel solutions. The B30 biofuel blend represents a significant step toward achieving a lower-carbon future for global shipping. The policy change is expected to accelerate the use of biofuels, which are derived from renewable sources and offer a substantial reduction in greenhouse gas emissions compared to traditional marine fuels.
For bunker suppliers and operators, the increased biofuel blend limit presents new opportunities to meet growing market demand for sustainable fuels. As the demand for cleaner shipping fuels intensifies, Singapore’s proactive stance on biofuel integration provides a clear pathway for bunker operators to invest in cleaner technologies and reduce their carbon footprints.
Industry Collaboration for a Greener Future
The announcement is part of Singapore’s ongoing efforts to collaborate with international and local stakeholders to address the environmental challenges facing the maritime industry. By facilitating biofuel adoption, MPA is helping to foster a cleaner, more sustainable maritime industry while ensuring that regulations evolve in tandem with technological advancements in marine fuels.
The MPA’s dedication to sustainable shipping practices is further demonstrated by its active participation in the IMO’s discussions on biofuel carriage guidelines. The port’s willingness to adopt and implement the draft guidance early provides a clear signal of Singapore’s leadership in driving the decarbonization of global shipping.
