SUPERBA against its type
Built in 2014, it is 4 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 25,269 gross tonnage it is larger than 59% 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 same builder is recorded for 192 other vessels here, 87 of them chemical tankers. The reported port of registry changed: NASSAU (2018–2022), then Valletta (2023–2025).
Its 7,723 t of CO₂ for 2025 is 40% 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 280.0 kg CO₂, 12% above the type median of 250.2 kg. It logged 2,620 hours at sea against a median of 2,109 hours for its type that year. 10.6% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2023 (13,812 t) and the lowest 2024 (7,539 t). Its efficiency percentile within the type went from 42 in 2019 to 64 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 862 of 1,348 qualifying chemical tankers by EEOI, at the 64th percentile. The dashed line is the type median, 14.4; this vessel reported 18.2.
EEOI divides emissions by transport work, which for this vessel and year was 425,061,640 tonne-miles over 27,584 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 24.1% lower than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 2.4% while distance sailed rose 0.3%and CO₂ per nautical mile rose 2.2%.That points mainly to how efficiently it sailed, rather than the other.
