YM SATURN against its type
Built in 2007, it is 3 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 10,917 gross tonnage it is smaller than 80% 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. The returns for 2021–2025 all give Valletta as port of registry.
Its 5,797 t of CO₂ for 2025 is close to the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 239.5 kg CO₂, close to the type median of 250.2 kg. It logged 2,474 hours at sea against a median of 2,109 hours for its type that year. 10.2% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2024 (7,684 t) and the lowest 2025 (5,797 t). Its efficiency percentile within the type went from 69 in 2021 to 83 in 2025 (lower is more efficient). Of the 5 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 1,122 of 1,348 qualifying chemical tankers by EEOI, at the 83rd percentile. The dashed line is the type median, 14.4; this vessel reported 29.1.
EEOI divides emissions by transport work, which for this vessel and year was 199,075,206 tonne-miles over 24,203 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 15.4% lower than in 2021, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions fell 24.6% while distance sailed fell 30.9%and CO₂ per nautical mile rose 9.2%.That points mainly to how much the vessel sailed, rather than the other.
