MAERSK NORTHWOOD against its type
Built in 2001, it is 7 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 26,626 gross tonnage it is smaller than 69% of the other 3,000 container ships with a recorded tonnage. It is one of 3 container ships here under the Palau flag, 0.1% 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 MAERSK NORTHWOOD for 2018–2024 and NORTHWOOD for 2025. The reported port of registry changed: Singapore (2018–2024), then Malakal Harbor (2025).
Its 12,833 t of CO₂ for 2025 is 22% 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 302.4 kg CO₂, 45% below the type median of 545.6 kg. It logged 5,257 hours at sea against a median of 3,155 hours for its type that year. 4.4% 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 (43,627 t) and the lowest 2020 (2,376 t). Its efficiency percentile within the type went from 87 in 2018 to 80 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,479 of 1,838 qualifying container ships by EEOI, at the 80th percentile. The dashed line is the type median, 14.2; this vessel reported 26.1.
EEOI divides emissions by transport work, which for this vessel and year was 490,763,289 tonne-miles over 42,440 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 70.6% 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 29.4% while distance sailed fell 14.8%and CO₂ per nautical mile fell 17.2%.
