ALTAIR LEADER against its type
Built in 2011, it is 3 years newer than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). At 60,394 gross tonnage it is larger than 67% 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 returns for 2018–2024 all give TOKYO as port of registry.
Its 2,639 t of CO₂ for 2024 is 69% below the median of 8,474 t among the 465 vehicle carriers on this register that reported for 2024. Per nautical mile it emitted 283.4 kg CO₂, 12% below the type median of 320.4 kg. It logged 675 hours at sea against a median of 1,799 hours for its type that year. 0.0% of its 2024 emissions were at berth; the median for vehicle carriers was 2.2%. Across 7 years with reported emissions, the highest was 2018 (14,574 t) and the lowest 2023 (401 t). Its efficiency percentile within the type went from 55 in 2018 to 50 in 2022 (lower is more efficient).

Reported CO₂ by year
Reported CO₂ in 2024 was 81.9% lower than in 2018, for EU/EEA voyages only.
From 2023 to 2024, emissions rose 557.6% and CO₂ per nautical mile fell 5.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
