POLAR ACE 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 2019–2025 all give MAJURO as port of registry.
Its 13,936 t of CO₂ for 2025 is 1.8 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 405.1 kg CO₂, close to the type median of 403.2 kg. It logged 2,843 hours at sea against a median of 2,030 hours for its type that year. 5.6% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 6 years with reported emissions, the highest was 2025 (13,936 t) and the lowest 2023 (2,283 t). Its efficiency percentile within the type went from 7 in 2019 to 24 in 2025 (lower is more efficient). Of the 3 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 343 of 1,448 qualifying oil tankers by EEOI, at the 24th percentile. The dashed line is the type median, 7.5; this vessel reported 5.5.
EEOI divides emissions by transport work, which for this vessel and year was 2,520,005,425 tonne-miles over 34,399 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 3.6% 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 rose 364.7% while distance sailed rose 371.5%and CO₂ per nautical mile fell 1.4%.That points mainly to how much the vessel sailed, rather than the other.
