AQUARIUS LEADER against its type

Built in 1998, it is 10 years older than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). At 58,329 gross tonnage it is smaller than 55% of the other 571 vehicle carriers with a recorded tonnage. It is one of 177 vehicle carriers here under the Panama flag, 24.8% 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: TOKYO (2018–2020), then PANAMA (2021–2025).

Its 2,271 t of CO₂ for 2025 is 68% below the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 281.4 kg CO₂, close to the type median of 309.1 kg. It logged 689 hours at sea against a median of 1,639 hours for its type that year. 4.2% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 8 years with reported emissions, the highest was 2023 (9,744 t) and the lowest 2025 (2,271 t). Its efficiency percentile within the type went from 42 in 2018 to 17 in 2025 (lower is more efficient). Of the 4 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 74 of 423 qualifying vehicle carriers by EEOI, at the 17th percentile. The dashed line is the type median, 51.7; this vessel reported 38.1.

EEOI divides emissions by transport work, which for this vessel and year was 59,597,375 tonne-miles over 8,068 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 66.1% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 43.8% and CO₂ per nautical mile rose 1.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
