EQUULEUS LEADER against its type
Built in 2005, it is 3 years older than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). At 62,393 gross tonnage it is larger than 74% 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 136 other vessels here, 36 of them vehicle carriers. Nippon Yusen is linked to 11 vessels on this register. The returns for 2018–2024 all give TOKYO as port of registry.
Its 4,336 t of CO₂ for 2025 is 39% below the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 322.0 kg CO₂, close to the type median of 309.1 kg. It logged 998 hours at sea against a median of 1,639 hours for its type that year. 3.3% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 4 years with reported emissions, the highest was 2018 (7,119 t) and the lowest 2023 (2,378 t). Its efficiency percentile within the type went from 4 in 2018 to 50 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 210 of 423 qualifying vehicle carriers by EEOI, at the 50th percentile. The dashed line is the type median, 51.7; this vessel reported 51.6.
Across the 9 ranked vessels operated by Nippon Yusen, the median percentile is 40. This vessel is less efficient than its own fleet median.
EEOI divides emissions by transport work, which for this vessel and year was 84,006,199 tonne-miles over 13,467 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 39.1% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, 2022, so the series has gaps.
From 2024 to 2025, emissions fell 10.7% and CO₂ per nautical mile rose 0.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
