MARLIN MILLENNIA against its type
It is one of 474 chemical tankers here under the Marshall Islands flag, 20.2% of the 2,344 on the register. Its MRV returns name it MARLIN MILLENNIA for 2019 and STI MILLENNIA for 2022–2025. The reported port of registry changed: Singapore (2019–2022), then Majuro (2023–2025).
Its 3,780 t of CO₂ for 2025 is 32% 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 252.4 kg CO₂, close to the type median of 250.2 kg. It logged 1,216 hours at sea against a median of 2,106 hours for its type that year. 6.7% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2022 (8,066 t) and the lowest 2023 (2,582 t). Its efficiency percentile within the type went from 3 in 2019 to 10 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 136 of 1,348 qualifying chemical tankers by EEOI, at the 10th percentile. The dashed line is the type median, 14.4; this vessel reported 7.9.
EEOI divides emissions by transport work, which for this vessel and year was 476,728,878 tonne-miles over 14,976 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 17.9% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2024, so the series has gaps.
From 2023 to 2025, emissions rose 46.4% while distance sailed rose 49.8%and CO₂ per nautical mile fell 2.3%.That points mainly to how much the vessel sailed, rather than the other.
