AVANCE POLARIS against its type
It is one of 70 gas carriers here under the Marshall Islands flag, 10.2% of the 688 on the register. Its MRV returns name it AVANCE POLARIS for 2023 and BW POLARIS for 2025. The returns for 2023–2025 all give Majuro as port of registry.
Its 2,626 t of CO₂ for 2025 is 56% below the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 373.4 kg CO₂, 46% above the type median of 256.2 kg. It logged 572 hours at sea against a median of 1,943 hours for its type that year. 2.2% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Its efficiency percentile within the type went from 0 in 2023 to 81 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 236 of 292 qualifying gas carriers by EEOI, at the 81st percentile. The dashed line is the type median, 27.9; this vessel reported 64.2.
EEOI divides emissions by transport work, which for this vessel and year was 40,875,331 tonne-miles over 7,033 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 42.1% higher than in 2023, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions rose 42.1% while distance sailed rose 40.4%and CO₂ per nautical mile rose 1.2%.That points mainly to how much the vessel sailed, rather than the other.
