NEPTUNE HORIZON 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 2018–2025 all give Valletta as port of registry.
Its 13,489 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 243.4 kg CO₂, 21% below the type median of 309.1 kg. It logged 4,631 hours at sea against a median of 1,639 hours for its type that year. 7.4% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 8 years with reported emissions, the highest was 2022 (22,769 t) and the lowest 2021 (12,519 t). Its efficiency percentile within the type went from 82 in 2018 to 84 in 2025 (lower is more efficient). Of the 8 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.
