MAERSK ROUBAIX 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 9,957 gross tonnage it is smaller than 92% 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 160 other vessels here, 23 of them container ships. The returns for 2018–2025 all give Hong Kong as port of registry.
Its 1,535 t of CO₂ for 2025 is 91% 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 371.6 kg CO₂, 32% below the type median of 545.6 kg. It logged 816 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%. Across 4 years with reported emissions, the highest was 2022 (3,683 t) and the lowest 2021 (537 t). Of the 5 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 40.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2023, 2024, so the series has gaps.
From 2022 to 2025, emissions fell 58.3% and CO₂ per nautical mile rose 23.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
