• Fleet-wide EEOI down from 17.80 in 2023 to 14.40 in 2025, per AAL's 2025 Sustainability Report
• Super B-Class ships averaged 4.27 in 2024 and 4.99 in 2025
• Voyage optimisation and vessel monitoring also credited
• Zero environmental incidents reported over 2023 to 2025

Singapore-based multipurpose heavy lift carrier AAL Shipping says it has cut its fleet-wide carbon intensity by 19% since 2023.

The company's Energy Efficiency Operational Indicator (EEOI), a measure of CO2 emitted per tonne of cargo carried per nautical mile, fell from 17.80 in 2023 to 14.40 in 2025, AAL said in an emailed press release citing its 2025 Sustainability Report.

AAL attributes much of the gain to its third-generation 32,000 dwt Super B-Class fleet, introduced in 2024, which it says recorded the strongest energy efficiency of any ships in the fleet with average EEOI values of 4.27 in 2024 and 4.99 in 2025.

Ship & Bunker has reported on the series of Super B-Class deliveries from CSSC Huangpu Wenchong; the ships are methanol-ready but run on conventional fuel.

Voyage optimisation, vessel monitoring, and digital tools supporting fuel efficiency also contributed, the company said.

"By designing and investing in more efficient vessels alongside smarter operations, we are delivering tangible results today while building a fleet that is ready for the next stage of the industry's low-carbon transition," said AAL deputy head of engineering Yahaya Sanusi.

AAL set the results against a tightening regulatory backdrop of FuelEU Maritime, the EU Emissions Trading System, and the IMO's proposed Net-Zero Framework, which the company describes as a positive step for the environment.

"Early, transparent engagement with customers is essential, allowing us to develop practical, cost-effective solutions that work for all parties well ahead of implementation deadlines, minimising disruption to project execution," said global head of operations Markus Remmers.

The company also reported zero environmental incidents between 2023 and 2025.

AAL operates a fleet of 28 vessels carrying breakbulk, heavy lift, dry bulk, and project cargoes for the energy, renewables, infrastructure, and mining sectors.
