RHINE MAERSK against its type

Built in 2012, it is 4 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). 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 461 other vessels here, 155 of them container ships. The returns for 2018–2025 all give Copenhagen as port of registry.

Its 36,742 t of CO₂ for 2025 is 2.2 times the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 443.7 kg CO₂, 19% below the type median of 545.6 kg. It logged 6,082 hours at sea against a median of 3,155 hours for its type that year. 1.2% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 5 years with reported emissions, the highest was 2025 (36,742 t) and the lowest 2018 (781 t). Its efficiency percentile within the type went from 34 in 2022 to 48 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 887 of 1,838 qualifying container ships by EEOI, at the 48th percentile. The dashed line is the type median, 14.2; this vessel reported 13.8.

EEOI divides emissions by transport work, which for this vessel and year was 2,654,777,457 tonne-miles over 82,803 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 4,606.4% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, so the series has gaps.

From 2024 to 2025, emissions rose 575.5% while distance sailed rose 674.5%and CO₂ per nautical mile fell 12.8%.That points mainly to how much the vessel sailed, rather than the other.
