POSEIDON LEADER: CO₂ emissions 2018–2025

POSEIDON LEADER against its type

Built in 2007, it is 1 year older than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). At 63,001 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 6,431 t of CO₂ for 2025 is close to the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 262.6 kg CO₂, 15% below the type median of 309.1 kg. It logged 1,736 hours at sea against a median of 1,639 hours for its type that year. 2.7% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 7 years with reported emissions, the highest was 2018 (11,391 t) and the lowest 2022 (2,191 t). Its efficiency percentile within the type went from 59 in 2018 to 24 in 2025 (lower is more efficient). Of the 6 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 101 of 423 qualifying vehicle carriers by EEOI, at the 24th percentile. The dashed line is the type median, 51.7; this vessel reported 40.8.

EEOI divides emissions by transport work, which for this vessel and year was 157,665,359 tonne-miles over 24,494 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 43.5% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.

From 2024 to 2025, emissions rose 128.8% and CO₂ per nautical mile rose 10.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
