SEAWAYS NIAGARA against its type
Built in 2008, it is 2 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 30,109 gross tonnage it is larger than 93% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 402 chemical tankers here under the Liberia flag, 17.2% of the 2,344 on the register. Its MRV returns name it ALEXANDROS II for 2018 and OAKTREE for 2025.
Its 3,792 t of CO₂ for 2025 is 31% 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 287.0 kg CO₂, 15% above the type median of 250.2 kg. It logged 1,183 hours at sea against a median of 2,106 hours for its type that year. 12.1% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Its efficiency percentile within the type went from 47 in 2018 to 20 in 2025 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 269 of 1,348 qualifying chemical tankers by EEOI, at the 20th percentile. The dashed line is the type median, 14.4; this vessel reported 9.2.
EEOI divides emissions by transport work, which for this vessel and year was 413,492,912 tonne-miles over 13,212 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 8.5% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, 2022, 2023, 2024, so the series has gaps.
From 2018 to 2025, emissions rose 8.5% while distance sailed rose 41.0%and CO₂ per nautical mile fell 23.1%.That points mainly to how much the vessel sailed, rather than the other.
