EM HYDRA against its type
It is one of 976 container ships here under the Liberia flag, 27.9% of the 3,495 on the register. The returns for 2019–2025 all give Monrovia as port of registry.
Its 13,579 t of CO₂ for 2025 is 17% 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 301.3 kg CO₂, 45% below the type median of 545.6 kg. It logged 4,512 hours at sea against a median of 3,155 hours for its type that year. 5.7% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 7 years with reported emissions, the highest was 2025 (13,579 t) and the lowest 2023 (3,182 t). Its efficiency percentile within the type went from 81 in 2020 to 82 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,502 of 1,838 qualifying container ships by EEOI, at the 82nd percentile. The dashed line is the type median, 14.2; this vessel reported 27.7.
EEOI divides emissions by transport work, which for this vessel and year was 490,031,397 tonne-miles over 45,067 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 204.1% higher than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 140.7% while distance sailed rose 121.3%and CO₂ per nautical mile rose 8.8%.That points mainly to how much the vessel sailed, rather than the other.
