ORION LEADER against its type
Built in 1999, it is 9 years older than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). At 57,513 gross tonnage it is smaller than 63% of the other 571 vehicle carriers with a recorded tonnage. It is one of 66 vehicle carriers here under the Japan flag, 9.3% of the 713 on the register. The same builder is recorded for 323 other vessels here, 27 of them vehicle carriers. The returns for 2018–2025 all give TOKYO as port of registry.
Its 2,563 t of CO₂ for 2025 is 64% below the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 314.2 kg CO₂, close to the type median of 309.1 kg. It logged 589 hours at sea against a median of 1,639 hours for its type that year. 4.2% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 7 years with reported emissions, the highest was 2021 (9,105 t) and the lowest 2025 (2,563 t). Its efficiency percentile within the type went from 49 in 2018 to 22 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 92 of 423 qualifying vehicle carriers by EEOI, at the 22nd percentile. The dashed line is the type median, 51.7; this vessel reported 39.9.
EEOI divides emissions by transport work, which for this vessel and year was 64,307,326 tonne-miles over 8,159 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 42.8% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, so the series has gaps.
From 2024 to 2025, emissions fell 42.5% and CO₂ per nautical mile rose 5.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
