SEASPAN HUDSON against its type
Built in 2015, it is 7 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 112,967 gross tonnage it is larger than 82% of the other 3,000 container ships with a recorded tonnage. It is one of 362 container ships here under the Singapore flag, 10.4% of the 3,495 on the register. The same builder is recorded for 211 other vessels here, 61 of them container ships. Its MRV returns name it SEASPAN HUDSON for 2018–2023 and YOKOHAMA EXPRESS for 2024–2025. The reported port of registry changed: Hong Kong (2018–2024), then Singapore (2025).
Its 5,671 t of CO₂ for 2025 is 65% 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 740.8 kg CO₂, 36% above the type median of 545.6 kg. It logged 514 hours at sea against a median of 3,155 hours for its type that year. 1.5% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 6 years with reported emissions, the highest was 2018 (58,919 t) and the lowest 2025 (5,671 t). Its efficiency percentile within the type went from 24 in 2018 to 25 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 459 of 1,838 qualifying container ships by EEOI, at the 25th percentile. The dashed line is the type median, 14.2; this vessel reported 9.0.
EEOI divides emissions by transport work, which for this vessel and year was 629,380,688 tonne-miles over 7,655 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 90.4% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2022, so the series has gaps.
From 2024 to 2025, emissions fell 87.6% while distance sailed fell 85.4%and CO₂ per nautical mile fell 15.1%.That points mainly to how much the vessel sailed, rather than the other.
