ECO WEST COAST against its type
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 2021–2025 all give Majuro as port of registry.
Its 25,731 t of CO₂ for 2025 is 3.2 times the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 467.7 kg CO₂, 16% above the type median of 403.2 kg. It logged 5,056 hours at sea against a median of 2,030 hours for its type that year. 6.3% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 5 years with reported emissions, the highest was 2025 (25,731 t) and the lowest 2021 (9,852 t). Its efficiency percentile within the type went from 9 in 2021 to 60 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 866 of 1,448 qualifying oil tankers by EEOI, at the 60th percentile. The dashed line is the type median, 7.5; this vessel reported 8.2.
EEOI divides emissions by transport work, which for this vessel and year was 3,130,243,309 tonne-miles over 55,010 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 161.2% higher than in 2021, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 54.3% while distance sailed rose 44.2%and CO₂ per nautical mile rose 7.0%.That points mainly to how much the vessel sailed, rather than the other.
