ALDEBARAN 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 30 chemical tankers here under the Bahamas flag, 1.3% of the 2,344 on the register. The same builder is recorded for 192 other vessels here, 87 of them chemical tankers. The returns for 2018–2025 all give NASSAU as port of registry.
Its 9,685 t of CO₂ for 2025 is 1.8 times the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 301.2 kg CO₂, 20% above the type median of 250.2 kg. It logged 3,665 hours at sea against a median of 2,106 hours for its type that year. 15.8% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2019 (11,717 t) and the lowest 2018 (7,471 t). Its efficiency percentile within the type went from 61 in 2018 to 62 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 837 of 1,348 qualifying chemical tankers by EEOI, at the 62nd percentile. The dashed line is the type median, 14.4; this vessel reported 17.7.
EEOI divides emissions by transport work, which for this vessel and year was 548,110,922 tonne-miles over 32,153 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 29.6% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 18.9% while distance sailed rose 12.2%and CO₂ per nautical mile rose 6.0%.That points mainly to how much the vessel sailed, rather than the other.
