NAVE COSMOS against its type
Built in 2010, it is the same age as the median oil tanker on this register (build year 2010, 2,896 vessels with a known build year). At 17,846 gross tonnage it is smaller than 93% of the other 2,841 oil tankers with a recorded tonnage. It is one of 289 oil tankers here under the Malta flag, 8.1% of the 3,548 on the register. Its MRV returns name it NAVE COSMOS for 2019–2021 and SONGA COSMOS for 2023–2025. The returns for 2019–2025 all give Valletta as port of registry.
Its 10,331 t of CO₂ for 2025 is 30% above the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 362.5 kg CO₂, 10% below the type median of 403.2 kg. It logged 3,027 hours at sea against a median of 2,030 hours for its type that year. 13.6% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 6 years with reported emissions, the highest was 2024 (12,261 t) and the lowest 2020 (3,793 t). Its efficiency percentile within the type went from 83 in 2019 to 99 in 2025 (lower is more efficient). Of the 5 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 1,429 of 1,448 qualifying oil tankers by EEOI, at the 99th percentile. The dashed line is the type median, 7.5; this vessel reported 34.1.
EEOI divides emissions by transport work, which for this vessel and year was 302,791,911 tonne-miles over 28,502 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 169.3% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.
From 2024 to 2025, emissions fell 15.7% while distance sailed fell 17.8%and CO₂ per nautical mile rose 2.5%.That points mainly to how much the vessel sailed, rather than the other.
