ECO OCEANO CA 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 2022–2025 all give Majuro as port of registry.
Its 7,180 t of CO₂ for 2025 is close to the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 436.0 kg CO₂, close to the type median of 403.2 kg. It logged 1,359 hours at sea against a median of 2,030 hours for its type that year. 5.7% 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 (11,598 t) and the lowest 2022 (4,748 t). Its efficiency percentile within the type went from 62 in 2022 to 44 in 2025 (lower is more efficient). Of the 7 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 641 of 1,448 qualifying oil tankers by EEOI, at the 44th percentile. The dashed line is the type median, 7.5; this vessel reported 7.0.
EEOI divides emissions by transport work, which for this vessel and year was 1,024,286,733 tonne-miles over 16,467 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 51.2% higher than in 2022, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions fell 38.1% while distance sailed fell 30.4%and CO₂ per nautical mile fell 11.1%.That points mainly to how much the vessel sailed, rather than the other.
