NISEKO GALAXY against its type
Built in 2020, it is 10 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 16,484 gross tonnage it is smaller than 60% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 474 chemical tankers here under the Marshall Islands flag, 20.2% of the 2,344 on the register. The returns for 2021–2025 all give MAJURO as port of registry.
Its 4,084 t of CO₂ for 2025 is 26% below the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 273.4 kg CO₂, close to the type median of 250.2 kg. It logged 1,213 hours at sea against a median of 2,106 hours for its type that year. 16.8% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 5 years with reported emissions, the highest was 2024 (10,420 t) and the lowest 2025 (4,084 t). Its efficiency percentile within the type went from 43 in 2021 to 49 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 657 of 1,348 qualifying chemical tankers by EEOI, at the 49th percentile. The dashed line is the type median, 14.4; this vessel reported 14.2.
EEOI divides emissions by transport work, which for this vessel and year was 287,833,686 tonne-miles over 14,941 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 49.5% lower than in 2021, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 60.8% and CO₂ per nautical mile rose 3.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
