NEPTUNE KEFALONIA against its type

Built in 2009, it is 1 year newer than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). At 36,825 gross tonnage it is smaller than 92% 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 reported port of registry changed: Piraeus (2018–2019), then Valletta (2020–2025).

Its 15,553 t of CO₂ for 2025 is 2.2 times the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 235.9 kg CO₂, 24% below the type median of 309.1 kg. It logged 4,848 hours at sea against a median of 1,639 hours for its type that year. 5.0% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 8 years with reported emissions, the highest was 2018 (20,089 t) and the lowest 2021 (15,388 t). Its efficiency percentile within the type went from 85 in 2018 to 61 in 2025 (lower is more efficient). Of the 8 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.
