NEPTUNE KALLOS against its type
Built in 2010, it is 2 years newer than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). At 36,711 gross tonnage it is smaller than 93% of the other 571 vehicle carriers with a recorded tonnage. It is one of 31 vehicle carriers here under the Malta flag, 4.3% of the 713 on the register. The same builder is recorded for 983 other vessels here, 41 of them vehicle carriers. The returns for 2022–2025 all give Valletta as port of registry.
Its 13,780 t of CO₂ for 2025 is 1.9 times the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 230.9 kg CO₂, 25% below the type median of 309.1 kg. It logged 4,468 hours at sea against a median of 1,639 hours for its type that year. 4.4% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 4 years with reported emissions, the highest was 2023 (17,955 t) and the lowest 2022 (10,190 t). Its efficiency percentile within the type went from 85 in 2022 to 68 in 2025 (lower is more efficient). Of the 8 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 286 of 423 qualifying vehicle carriers by EEOI, at the 68th percentile. The dashed line is the type median, 51.7; this vessel reported 65.1.
EEOI divides emissions by transport work, which for this vessel and year was 211,583,756 tonne-miles over 59,684 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 35.2% higher than in 2022, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 22.2% while distance sailed fell 4.3%and CO₂ per nautical mile fell 18.7%.That points mainly to how efficiently it sailed, rather than the other.
