FIRMAMENT ACE 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). 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: NASSAU (2018–2020), then TOKYO (2021–2025).

Its 22,783 t of CO₂ for 2025 is 3.2 times the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 318.0 kg CO₂, close to the type median of 309.1 kg. It logged 4,355 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 2025 (22,783 t) and the lowest 2024 (322 t). Its efficiency percentile within the type was 73 in both 2018 and 2025. Of the 5 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 310 of 423 qualifying vehicle carriers by EEOI, at the 73rd percentile. The dashed line is the type median, 51.7; this vessel reported 71.7.

EEOI divides emissions by transport work, which for this vessel and year was 317,663,553 tonne-miles over 71,649 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 255.7% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.

From 2024 to 2025, emissions rose 6,984.4% and CO₂ per nautical mile fell 1.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.

Where the 2025 emissions occurred

Methane, nitrous oxide and EU ETS2025

Total CO₂ equivalent: 23,142 t
Methane (CH₄): 0.37 t
Nitrous oxide (N₂O): 1.32 t
Under EU ETS: 11,363 t, 50% of total

Laden voyages2025

CO₂ on laden voyages: 14,623 t, 64% of total
Fuel, laden: 4,693 t

The rest of the 2025 total was emitted on ballast legs or at berth.
