MAERSK CALABAR against its type
Built in 2011, it is 3 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 50,869 gross tonnage it is larger than 52% 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 983 other vessels here, 86 of them container ships. The returns for 2020–2025 all give Singapore as port of registry.
Its 22,787 t of CO₂ for 2025 is 39% above the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 480.2 kg CO₂, 12% below the type median of 545.6 kg. It logged 3,829 hours at sea against a median of 3,155 hours for its type that year. 0.7% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 7 years with reported emissions, the highest was 2024 (27,620 t) and the lowest 2019 (6,782 t). Its efficiency percentile within the type went from 48 in 2019 to 54 in 2025 (lower is more efficient). Of the 3 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 986 of 1,838 qualifying container ships by EEOI, at the 54th percentile. The dashed line is the type median, 14.2; this vessel reported 15.2.
EEOI divides emissions by transport work, which for this vessel and year was 1,504,066,007 tonne-miles over 47,448 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 236.0% higher than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 17.5% while distance sailed fell 27.2%and CO₂ per nautical mile rose 13.3%.That points mainly to how much the vessel sailed, rather than the other.
