YASA SWAN 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 2019–2025 all give MAJURO as port of registry.
Its 8,057 t of CO₂ for 2025 is 46% above the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 266.6 kg CO₂, close to the type median of 250.2 kg. It logged 2,504 hours at sea against a median of 2,106 hours for its type that year. 7.9% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2022 (19,325 t) and the lowest 2019 (6,133 t). Its efficiency percentile within the type went from 22 in 2019 to 10 in 2025 (lower is more efficient). Of the 5 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 134 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 1,018,529,709 tonne-miles over 30,223 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 31.4% higher than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 21.8% and CO₂ per nautical mile fell 4.3%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
