ATLANTAS II against its type
It is one of 30 chemical tankers here under the Bahamas flag, 1.3% of the 2,344 on the register. Its MRV returns name it ATLANTAS II for 2018–2020, SEAWAYS CHANIA for 2021, CHEMTRANS URANUS for 2022 and COAST BUSTER for 2025. The reported port of registry changed: MAJURO (2021), then Monrovia (2022), then NASSAU (2025).
Its 9,194 t of CO₂ for 2022 is 1.6 times the median of 5,807 t among the 1,486 chemical tankers on this register that reported for 2022. Per nautical mile it emitted 334.6 kg CO₂, 26% above the type median of 266.3 kg. It logged 2,494 hours at sea against a median of 1,995 hours for its type that year. 19.3% of its 2022 emissions were at berth; the median for chemical tankers was 8.6%. Across 5 years with reported emissions, the highest was 2020 (11,158 t) and the lowest 2018 (4,980 t). Its efficiency percentile within the type went from 38 in 2018 to 68 in 2022 (lower is more efficient). The one comparable vessel listed below with a 2022 return reported a lower CO₂ per nautical mile.
No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2022
Position 912 of 1,334 qualifying chemical tankers by EEOI, at the 68th percentile. The dashed line is the type median, 15.7; this vessel reported 20.9.
EEOI divides emissions by transport work, which for this vessel and year was 440,952,518 tonne-miles over 27,475 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2022 was 84.6% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2023, 2024, so the series has gaps.
From 2021 to 2022, emissions rose 56.0% while distance sailed rose 62.7%and CO₂ per nautical mile fell 4.1%.That points mainly to how much the vessel sailed, rather than the other.
