ATHENIAN against its type
Built in 2011, it is 3 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 100,000 gross tonnage it is larger than 79% 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 same builder is recorded for 563 other vessels here, 243 of them container ships. Its MRV returns name it ATHENIAN for 2018–2020 and MUNDRA EXPRESS for 2024–2025. The returns for 2018–2025 all give MONROVIA as port of registry.
Its 20,136 t of CO₂ for 2025 is 23% 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 846.0 kg CO₂, 1.6 times the type median of 545.6 kg. It logged 1,501 hours at sea against a median of 3,155 hours for its type that year. 0.8% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 5 years with reported emissions, the highest was 2019 (22,858 t) and the lowest 2020 (6,708 t). Its efficiency percentile within the type went from 23 in 2018 to 24 in 2025 (lower is more efficient). Of the 3 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 446 of 1,838 qualifying container ships by EEOI, at the 24th percentile. The dashed line is the type median, 14.2; this vessel reported 8.9.
EEOI divides emissions by transport work, which for this vessel and year was 2,254,839,866 tonne-miles over 23,800 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 22.5% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions rose 129.3% while distance sailed rose 96.2%and CO₂ per nautical mile rose 16.9%.That points mainly to how much the vessel sailed, rather than the other.
