ROTTERDAM STAR against its type
Built in 2008, it is the same age as the median container ship on this register (build year 2008, 3,088 vessels with a known build year). It is one of 976 container ships here under the Liberia flag, 27.9% of the 3,495 on the register. The same builder is recorded for 98 other vessels here, 35 of them container ships. Its MRV returns name it ROTTERDAM STAR for 2020–2021 and SUAPE EXPRESS for 2024–2025. The reported port of registry changed: MAJURO (2020–2021), then MONROVIA (2024–2025).
Its 43,653 t of CO₂ for 2025 is 2.7 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 605.5 kg CO₂, 11% above the type median of 545.6 kg. It logged 5,025 hours at sea against a median of 3,155 hours for its type that year. 1.8% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 4 years with reported emissions, the highest was 2025 (43,653 t) and the lowest 2024 (2,293 t). Its efficiency percentile within the type went from 63 in 2020 to 51 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 941 of 1,838 qualifying container ships by EEOI, at the 51st percentile. The dashed line is the type median, 14.2; this vessel reported 14.6.
EEOI divides emissions by transport work, which for this vessel and year was 2,994,016,461 tonne-miles over 72,094 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 27.8% higher than in 2020, for EU/EEA voyages only. No return is recorded for 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions rose 1,803.4% and CO₂ per nautical mile rose 21.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
