ALICE N against its type
Built in 2004, it is 6 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 5,551 gross tonnage it is smaller than 96% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 218 chemical tankers here under the Malta flag, 9.3% of the 2,344 on the register. Its MRV returns name it TEAM SAPPHIRE for 2018–2020, ALICE N for 2021 and NQ TULIPA for 2022–2025. The returns for 2018–2025 all give Valletta as port of registry.
Its 7,294 t of CO₂ for 2025 is 32% above the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 149.6 kg CO₂, 40% below the type median of 250.2 kg. It logged 5,414 hours at sea against a median of 2,109 hours for its type that year. 11.5% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2018 (8,730 t) and the lowest 2024 (6,149 t). Its efficiency percentile within the type went from 88 in 2018 to 94 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,273 of 1,348 qualifying chemical tankers by EEOI, at the 94th percentile. The dashed line is the type median, 14.4; this vessel reported 42.5.
EEOI divides emissions by transport work, which for this vessel and year was 171,782,854 tonne-miles over 48,759 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 16.4% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 18.6% while distance sailed rose 15.9%and CO₂ per nautical mile rose 2.3%.That points mainly to how much the vessel sailed, rather than the other.
