MSC GEMMA 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 2023–2025 all give Monrovia as port of registry.
Its 4,763 t of CO₂ for 2025 is 71% 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 1,245.2 kg CO₂, 2.3 times the type median of 545.6 kg. It logged 564 hours at sea against a median of 3,155 hours for its type that year. 18.5% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 3 years with reported emissions, the highest was 2024 (69,055 t) and the lowest 2025 (4,763 t). Its efficiency percentile within the type went from 16 in 2023 to 11 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 8 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 210 of 1,838 qualifying container ships by EEOI, at the 11th percentile. The dashed line is the type median, 14.2; this vessel reported 7.2.
EEOI divides emissions by transport work, which for this vessel and year was 666,114,685 tonne-miles over 3,825 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 37.1% lower than in 2023, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 93.1% while distance sailed fell 93.7%and CO₂ per nautical mile rose 9.4%.That points mainly to how much the vessel sailed, rather than the other.
