MAERSK BOSTON against its type
Built in 2006, it is 2 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 48,853 gross tonnage it is larger than 51% of the other 3,000 container ships with a recorded tonnage. It is one of 119 container ships here under the Denmark flag, 3.4% of the 3,495 on the register. The same builder is recorded for 35 other vessels here, 26 of them container ships. Its MRV returns name it SEAGO ANTWERP for 2018–2020 and MAERSK BOSTON for 2021–2024. The reported port of registry changed: Copenhagen (2018), then Kobenhavn (2019–2024).
Its 15,027 t of CO₂ for 2024 is 15% below the median of 17,769 t among the 2,101 container ships on this register that reported for 2024. Per nautical mile it emitted 623.5 kg CO₂, 18% above the type median of 528.5 kg. It logged 1,838 hours at sea against a median of 3,325 hours for its type that year. 1.4% of its 2024 emissions were at berth; the median for container ships was 2.8%. Across 5 years with reported emissions, the highest was 2018 (51,377 t) and the lowest 2024 (15,027 t). Its efficiency percentile within the type went from 62 in 2018 to 91 in 2024 (lower is more efficient). The one sister ship listed below with a 2024 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2024
Position 1,516 of 1,661 qualifying container ships by EEOI, at the 91st percentile. The dashed line is the type median, 15.4; this vessel reported 42.6.
EEOI divides emissions by transport work, which for this vessel and year was 352,572,736 tonne-miles over 24,101 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 70.8% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2022, 2023, so the series has gaps.
From 2021 to 2024, emissions fell 1.0% while distance sailed rose 15.2%and CO₂ per nautical mile fell 14.1%.
