HERCULES LEADER against its type
Built in 2011, it is 3 years newer than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). At 63,083 gross tonnage it is larger than 77% 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 102 other vessels here, 50 of them vehicle carriers. The returns for 2018–2025 all give TOKYO as port of registry.
Its 11,207 t of CO₂ for 2025 is 1.6 times the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 285.0 kg CO₂, close to the type median of 309.1 kg. It logged 2,735 hours at sea against a median of 1,639 hours for its type that year. 3.0% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 6 years with reported emissions, the highest was 2025 (11,207 t) and the lowest 2023 (927 t). Its efficiency percentile within the type went from 68 in 2018 to 16 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 68 of 423 qualifying vehicle carriers by EEOI, at the 16th percentile. The dashed line is the type median, 51.7; this vessel reported 37.3.
EEOI divides emissions by transport work, which for this vessel and year was 300,461,126 tonne-miles over 39,325 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 60.7% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2022, so the series has gaps.
From 2024 to 2025, emissions rose 114.5% and CO₂ per nautical mile fell 3.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
