JOST against its type
Built in 2010, it is 2 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 16,137 gross tonnage it is smaller than 82% of the other 3,000 container ships with a recorded tonnage. It is one of 976 container ships here under the Liberia flag, 27.9% of the 3,495 on the register. The same builder is recorded for 127 other vessels here, 46 of them container ships. Its MRV returns name it JOST for 2023–2024 and MARTI SPIRIT for 2025. The reported port of registry changed: MADEIRA (2023–2024), then Monrovia (2025).
Its 9,263 t of CO₂ for 2025 is 43% below the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 251.3 kg CO₂, 54% below the type median of 545.6 kg. It logged 3,394 hours at sea against a median of 3,155 hours for its type that year. 1.4% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 3 years with reported emissions, the highest was 2024 (11,190 t) and the lowest 2023 (7,958 t). Its efficiency percentile within the type went from 90 in 2023 to 86 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.
