CEPHEUS LEADER against its type
Built in 2006, it is 2 years older than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). At 62,571 gross tonnage it is larger than 75% 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 307 other vessels here, 55 of them vehicle carriers. The reported port of registry changed: PANAMA (2018), then FUKUOKA (2019–2024).
Its 1,261 t of CO₂ for 2025 is 82% below the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 289.2 kg CO₂, close to the type median of 309.1 kg. It logged 374 hours at sea against a median of 1,639 hours for its type that year. 7.1% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 8 years with reported emissions, the highest was 2024 (10,433 t) and the lowest 2025 (1,261 t). Its efficiency percentile within the type went from 47 in 2018 to 15 in 2023 (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 87.3% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 87.9% and CO₂ per nautical mile fell 7.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
