The regulatory requirements governing environmental performance continue to ratchet up, with the EU Emissions Trading System in place for large ships entering EU ports since January 2024, FuelEU Maritime in effect since January 2025 and the IMO’s Carbon Intensity Indicator tightening. At the same time, negotiations continue over the IMO’s Net Zero Framework. For us, however, efficiency is a long-term operating discipline, not a reaction to each new rule.
At year-end 2025, we had 26 product and chemical tankers in operation and our latest Sustainability Report identifies 13 diverse energy efficiency technologies in use on our vessels, from Mewis Ducts and propeller boss cap fins to variable speed drives and low-load boiler optimization, as well as DeepSea’s AI-enabled voyage optimization, and weather-routing services from WetterWelt, all of which combine to support more fuel-efficient operations across the fleet.
In 2025, we also purchased and used biofuel blends of up to B30 to achieve full FuelEU Maritime compliance. Our technical teams and onboard crews made that possible, managing fuel handling, storage and combustion while safeguarding vessel performance throughout the voyages. Their work showed that biofuels can be operationally viable at scale.
This progress is borne out in the data. Fleet emissions decreased from 422,083 metric tons of CO2 in 2024 to 361,656 in 2025, a 14% reduction. Trade patterns, waiting time in port, drydocking days and fleet utilization also influence year-on-year emissions, so the decrease cannot be attributed to any single measure. Our focus instead is on sustained improvements in vessel efficiency and fuel consumption.
In 2025, our fleet recorded zero Port State Control detentions, and 81% of Port State Control inspections recorded zero deficiencies. This, in turn, is only made possible by our people. Seafarers can access on-demand training through the AFLIX app, use virtual reality to familiarize themselves with vessels before joining, and provide anonymous peer feedback on safety competencies through our Safety Rating app. Every member of our shore-based team also visited a vessel during the year, strengthening the connection between ship and shore. What’s more, our WAVES initiative, which supports women at sea, helped grow our community of women officers from 16 to 25 in 2025.
As regulatory requirements evolve, we will keep improving vessel efficiency through practical investment, informed decision-making and the expertise of our people. Technology has an important role to play, but its value depends on how effectively it is integrated into day-to-day vessel operations. That commitment to continuous improvement is central to how we deliver performance and progress.
Ardmore Shipping owns and operates a fleet of modern, fuel-efficient product and chemical tankers, delivering energy, mobility and essential commodities in support of global trade.
