YASA ORION 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. The returns for 2022–2025 all give MAJURO as port of registry.
Its 3,952 t of CO₂ for 2025 is 29% 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 303.7 kg CO₂, 21% above the type median of 250.2 kg. It logged 1,223 hours at sea against a median of 2,106 hours for its type that year. 11.0% 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 (5,570 t) and the lowest 2023 (2,083 t). Its efficiency percentile within the type went from 57 in 2022 to 30 in 2025 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 402 of 1,348 qualifying chemical tankers by EEOI, at the 30th percentile. The dashed line is the type median, 14.4; this vessel reported 11.0.
EEOI divides emissions by transport work, which for this vessel and year was 360,550,182 tonne-miles over 13,011 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 29.0% lower than in 2022, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 28.3% and CO₂ per nautical mile rose 4.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
