FRONT SIRIUS 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 2018–2025 all give Majuro as port of registry.
Its 17,093 t of CO₂ for 2025 is 2.2 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 438.2 kg CO₂, close to the type median of 403.2 kg. It logged 3,886 hours at sea against a median of 2,030 hours for its type that year. 13.3% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2022 (22,010 t) and the lowest 2018 (5,136 t). Its efficiency percentile within the type went from 18 in 2018 to 47 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 677 of 1,448 qualifying oil tankers by EEOI, at the 47th percentile. The dashed line is the type median, 7.5; this vessel reported 7.2.
EEOI divides emissions by transport work, which for this vessel and year was 2,377,344,924 tonne-miles over 39,010 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 232.8% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 32.3% while distance sailed rose 72.4%and CO₂ per nautical mile fell 23.3%.That points mainly to how much the vessel sailed, rather than the other.
