COURAGEOUS ACE against its type

Built in 2003, it is 5 years older than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). At 56,563 gross tonnage it is smaller than 66% 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 69 other vessels here, 28 of them vehicle carriers. Its MRV returns name it COURAGEOUS ACE for 2018–2023 and MORNING CREST for 2025. The returns for 2018–2025 all give TOKYO as port of registry.

Its 4,879 t of CO₂ for 2025 is 31% below the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 273.6 kg CO₂, 11% below the type median of 309.1 kg. It logged 1,182 hours at sea against a median of 1,639 hours for its type that year. 2.3% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 6 years with reported emissions, the highest was 2019 (6,921 t) and the lowest 2022 (260 t). Its efficiency percentile within the type went from 26 in 2018 to 15 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2025

Position 64 of 423 qualifying vehicle carriers by EEOI, at the 15th percentile. The dashed line is the type median, 51.7; this vessel reported 36.8.

EEOI divides emissions by transport work, which for this vessel and year was 132,656,879 tonne-miles over 17,834 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 4.1% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2024, so the series has gaps.

From 2023 to 2025, emissions rose 59.4% and CO₂ per nautical mile fell 11.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
