PRECIOUS ACE against its type
Built in 2010, it is 2 years newer than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). 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 136 other vessels here, 36 of them vehicle carriers. The reported port of registry changed: GEORGE TOWN (2018–2019), then TOKYO (2020–2025).
Its 4,058 t of CO₂ for 2025 is 43% below the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 257.5 kg CO₂, 17% below the type median of 309.1 kg. It logged 1,070 hours at sea against a median of 1,639 hours for its type that year. 1.0% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 7 years with reported emissions, the highest was 2022 (6,452 t) and the lowest 2020 (2,000 t). Its efficiency percentile within the type went from 84 in 2018 to 88 in 2022 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 34.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions rose 52.4% and CO₂ per nautical mile fell 14.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
