Its 9,166 t of CO₂ for 2025 is 30% above the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 270.2 kg CO₂, 13% below the type median of 309.1 kg. It logged 2,323 hours at sea against a median of 1,639 hours for its type that year. 3.6% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 5 years with reported emissions, the highest was 2020 (17,984 t) and the lowest 2019 (254 t). Its efficiency percentile within the type went from 56 in 2018 to 71 in 2025 (lower is more efficient). Of the 7 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 300 of 423 qualifying vehicle carriers by EEOI, at the 71st percentile. The dashed line is the type median, 51.7; this vessel reported 67.1.

Reported CO₂ in 2025 was 354.5% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2022, 2023, 2024, so the series has gaps.

From 2021 to 2025, emissions rose 127.0% while distance sailed rose 190.6%and CO₂ per nautical mile fell 21.9%.That points mainly to how much the vessel sailed, rather than the other.
