Efficiency against its own type2025
Position 1,173 of 1,838 qualifying container ships by EEOI, at the 64th percentile. The dashed line is the type median, 14.2; this vessel reported 18.1.
EEOI divides emissions by transport work, which for this vessel and year was 552,027,057 tonne-miles over 47,703 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 626.3% higher than in 2023, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 28.9% and CO₂ per nautical mile fell 8.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
