MAERSK BAHAMAS against its type
Built in 2016, it is 8 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 28,316 gross tonnage it is smaller than 66% 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 101 other vessels here, 74 of them container ships. Its MRV returns name it NORDSERENA for 2018 and MAERSK BAHAMAS for 2019–2025. The returns for 2021–2025 all give Singapore as port of registry.
Its 11,683 t of CO₂ for 2025 is 29% 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 306.7 kg CO₂, 44% below the type median of 545.6 kg. It logged 2,703 hours at sea against a median of 3,155 hours for its type that year. 2.2% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 7 years with reported emissions, the highest was 2023 (27,190 t) and the lowest 2025 (11,683 t). Its efficiency percentile within the type went from 72 in 2018 to 77 in 2025 (lower is more efficient). Of the 5 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 1,413 of 1,838 qualifying container ships by EEOI, at the 77th percentile. The dashed line is the type median, 14.2; this vessel reported 23.8.
EEOI divides emissions by transport work, which for this vessel and year was 490,249,266 tonne-miles over 38,095 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 0.2% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2024 to 2025, emissions fell 36.0% while distance sailed fell 36.1%and CO₂ per nautical mile rose 0.1%.That points mainly to how much the vessel sailed, rather than the other.
