NYK DELPHINUS against its type
Built in 2007, it is 1 year older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 55,487 gross tonnage it is larger than 57% 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 761 other vessels here, 355 of them container ships. Its MRV returns name it NYK DELPHINUS for 2020–2022 and DELPHINUS C for 2023–2025. The returns for 2020–2025 all give Liberia as port of registry.
Its 3,746 t of CO₂ for 2025 is 77% 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 601.8 kg CO₂, 10% above the type median of 545.6 kg. It logged 431 hours at sea against a median of 3,155 hours for its type that year. 3.1% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 6 years with reported emissions, the highest was 2020 (18,019 t) and the lowest 2025 (3,746 t). Its efficiency percentile within the type went from 53 in 2020 to 56 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,027 of 1,838 qualifying container ships by EEOI, at the 56th percentile. The dashed line is the type median, 14.2; this vessel reported 15.8.
EEOI divides emissions by transport work, which for this vessel and year was 236,312,303 tonne-miles over 6,224 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 79.2% lower than in 2020, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 56.5% while distance sailed fell 60.5%and CO₂ per nautical mile rose 10.2%.That points mainly to how much the vessel sailed, rather than the other.
