YASA SOUTHERN CROSS against its type
Built in 2012, it is 2 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 164,169 gross tonnage it is larger than 98% of the other 2,841 oil tankers with a recorded tonnage. It is one of 793 oil tankers here under the Marshall Islands flag, 22.4% of the 3,548 on the register. The returns for 2023–2025 all give MAJURO as port of registry.
Its 5,534 t of CO₂ for 2025 is 30% below the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 764.6 kg CO₂, 1.9 times the type median of 403.2 kg. It logged 721 hours at sea against a median of 2,030 hours for its type that year. 5.3% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 3 years with reported emissions, the highest was 2023 (30,823 t) and the lowest 2025 (5,534 t). Its efficiency percentile within the type went from 11 in 2023 to 7 in 2025 (lower is more efficient). Of the 2 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 96 of 1,448 qualifying oil tankers by EEOI, at the 7th percentile. The dashed line is the type median, 7.5; this vessel reported 4.1.
EEOI divides emissions by transport work, which for this vessel and year was 1,356,446,078 tonne-miles over 7,238 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 82.0% lower than in 2023, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 78.3% and CO₂ per nautical mile fell 1.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
