MAERSK TANJONG 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 94,193 gross tonnage it is larger than 74% of the other 3,000 container ships with a recorded tonnage. It is one of 202 container ships here under the Hong Kong flag, 5.8% of the 3,495 on the register. The same builder is recorded for 660 other vessels here, 231 of them container ships. The returns for 2021–2025 all give Hong Kong as port of registry.
Its 18,029 t of CO₂ for 2025 is 10% 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 658.1 kg CO₂, 21% above the type median of 545.6 kg. It logged 1,712 hours at sea against a median of 3,155 hours for its type that year. 0.6% of its 2025 emissions were at berth; the median for container ships was 3.2%. Of the 2 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 496 of 1,838 qualifying container ships by EEOI, at the 27th percentile. The dashed line is the type median, 14.2; this vessel reported 9.4.
EEOI divides emissions by transport work, which for this vessel and year was 1,922,077,825 tonne-miles over 27,395 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 338.9% higher than in 2021, for EU/EEA voyages only. No return is recorded for 2023, 2024, so the series has gaps.
From 2021 to 2025, emissions rose 338.9% and CO₂ per nautical mile fell 14.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
