RIGEL LEADER against its type
Built in 2012, it is 4 years newer than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). At 59,694 gross tonnage it is larger than 61% 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. The reported port of registry changed: PANAMA (2018–2020), then Japan (2025).
Its 12,428 t of CO₂ for 2025 is 1.8 times the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 260.2 kg CO₂, 16% below the type median of 309.1 kg. It logged 3,236 hours at sea against a median of 1,639 hours for its type that year. 1.4% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 3 years with reported emissions, the highest was 2025 (12,428 t) and the lowest 2018 (2,807 t). Its efficiency percentile within the type went from 46 in 2018 to 55 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 232 of 423 qualifying vehicle carriers by EEOI, at the 55th percentile. The dashed line is the type median, 51.7; this vessel reported 54.0.
EEOI divides emissions by transport work, which for this vessel and year was 230,267,371 tonne-miles over 47,767 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 342.7% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2021, 2022, 2023, 2024, so the series has gaps.
From 2020 to 2025, emissions rose 295.7% while distance sailed rose 340.9%and CO₂ per nautical mile fell 10.3%.That points mainly to how much the vessel sailed, rather than the other.
