ZEBRA against its type

Built in 2001, it is 7 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 27,093 gross tonnage it is smaller than 67% of the other 3,000 container ships with a recorded tonnage. It is one of 976 container ships here under the Liberia flag, 27.9% of the 3,495 on the register. The returns for 2020–2025 all give Monrovia as port of registry.

Its 12,008 t of CO₂ for 2025 is 27% 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 473.5 kg CO₂, 13% below the type median of 545.6 kg. It logged 2,142 hours at sea against a median of 3,155 hours for its type that year. 2.9% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 4 years with reported emissions, the highest was 2023 (24,040 t) and the lowest 2020 (2,810 t). Its efficiency percentile within the type went from 78 in 2023 to 86 in 2025 (lower is more efficient). Of the 3 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,584 of 1,838 qualifying container ships by EEOI, at the 86th percentile. The dashed line is the type median, 14.2; this vessel reported 32.8.

Reported CO₂ in 2025 was 327.3% higher than in 2020, for EU/EEA voyages only. No return is recorded for 2021, 2022, so the series has gaps.

From 2024 to 2025, emissions fell 50.0% while distance sailed fell 53.8%and CO₂ per nautical mile rose 8.1%.That points mainly to how much the vessel sailed, rather than the other.
