Industry coalition SEA-LNG has published its annual 'View from the Bridge' report, showing that LNG-powered vessels ordered in 2025 accounted for 79% of alternative-fuelled tonnage, up from 67% in 2024.

The report, titled 'The Journey,' highlights what the organisation describes as a decade of progress towards cleaner shipping, supported by over $150bn of investment to increase the use of LNG as a marine fuel.

The LNG-powered global fleet — both operating and on order, including LNG carriers — now represents 10% of the global fleet by deadweight tonnage, according to the report. LNG bunkering is offered in 222 ports globally, while the number of bunkering vessels has increased from a single vessel in 2016 to over 62 in 2025, with 38 on order.

The report also addresses developments in liquefied biomethane (LBM), with new research mapping biomethane bunkering availability, as well as nascent supplies of e-methane.

SEA-LNG argues that LNG's energy density, availability, lower costs of regulatory compliance, and commercial optionality give it advantages over other alternative marine fuels.

The 'View from the Bridge' sets out what the coalition describes as the tenets of technology-neutral global regulations that would balance commerciality and sustainability. It calls for a global regulatory system that rewards clean fuel supply chains, protects first movers, and is practical considering the global maritime industry.

Peter Keller, chairman of SEA-LNG, said: "After a year of regulatory drama exposing the complexity of the task faced by the IMO, the need for a single global decarbonisation framework is greater than ever. This framework must be goal-based and technology-neutral. It must allow some flexibility so companies can plan their fleet modernisation. We need a framework which is practical and realistic, incentivising solutions that are scalable and investable."

Steve Esau, chief operating officer of SEA-LNG, added: "2025 is the year the methane decarbonisation pathway became a clear runway. The year our advocacy for LNG as a transition fuel from fossil LNG through liquefied biomethane to liquefied e-methane took off, with record amounts of LBM powering global shipping today and growing strongly into the future."

Ian Aitchison, SEA-LNG's communications director, noted: "SEA-LNG's messaging is built upon sound science, and the professional expertise and experience of the coalition's members. So, despite the environmental and regulatory tumult experienced by the maritime industry, our voice has remained consistent over the last decade. In a world increasingly filled with AI content, being a credible and trusted advocate for a cleaner future is more important than ever."

SEA-LNG is a UK-registered not-for-profit collaborative industry foundation with members across the LNG value chain, including providers, users, engine and asset suppliers, and class societies.
