MONTE ROSA against its type
Built in 2006, it is 4 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 42,403 gross tonnage it is smaller than 62% 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. Its MRV returns name it SEAWAYS VISAYAS for 2021 and MONTE ROSA for 2025. The returns for 2021–2025 all give Majuro as port of registry.
Its 2,220 t of CO₂ for 2025 is 72% 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 393.5 kg CO₂, close to the type median of 403.2 kg. It logged 475 hours at sea against a median of 2,030 hours for its type that year. 15.6% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Its efficiency percentile within the type went from 70 in 2021 to 53 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 767 of 1,448 qualifying oil tankers by EEOI, at the 53rd percentile. The dashed line is the type median, 7.5; this vessel reported 7.7.
EEOI divides emissions by transport work, which for this vessel and year was 288,713,914 tonne-miles over 5,642 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 10.5% lower than in 2021, for EU/EEA voyages only. No return is recorded for 2022, 2023, 2024, so the series has gaps.
From 2021 to 2025, emissions fell 10.5% while distance sailed rose 11.1%and CO₂ per nautical mile fell 19.5%.That points mainly to how efficiently it sailed, rather than the other.
