Global Shipping Decarbonisation Trends in 2025

2025 is shaping up to be a turning point for the decarbonisation of shipping. Beyond regulatory milestones like the IMO Net-Zero Framework, innovation and investment are accelerating solutions across the sector.

Key Highlights from 2025:

• Decarbonisation remains a strategic priority, as confirmed by the recent Global Maritime Decarbonisation Survey (conducted by GCMD and BCG), showing that global operators remain committed despite economic headwinds.

• Innovative propulsion technologies are gaining traction: methanol-powered vessels are a reality, with the world’s first methanol-fueled tug operating in Europe.

• A bold carbon capture solution from startup Seabound is being deployed. This modular quicklime system absorbs up to 78% of CO² and 90% of sulfur emissions, offering a transitional tool compatible with emerging IMO frameworks.

• Meanwhile, wind-assisted propulsion systems (WAPS) are spreading, rotor sails are delivering 20~40% fuel savings, proving that old-school wind combined with modern tech has a valuable place in fleet efficiency.

Why It Matters?

These developments reflect a collective push toward cleaner shipping, combining environmental, regulatory, and commercial incentives. High-quality solutions like AUS40 are vital complements, delivering NOx reduction in the here-and-now while alternative fuel ecosystems scale up.
