ALANA against its type
Built in 2004, it is 4 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 11,662 gross tonnage it is smaller than 86% of the other 3,000 container ships with a recorded tonnage. It is one of 307 container ships here under the Portugal flag, 8.8% of the 3,495 on the register. The same builder is recorded for 180 other vessels here, 110 of them container ships. The returns for 2018–2025 all give Madeira as port of registry.
Its 9,254 t of CO₂ for 2025 is 43% 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 229.6 kg CO₂, 58% below the type median of 545.6 kg. It logged 3,829 hours at sea against a median of 3,155 hours for its type that year. 5.3% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2018 (14,185 t) and the lowest 2024 (7,777 t). Its efficiency percentile within the type went from 74 in 2018 to 92 in 2025 (lower is more efficient). Of the 5 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 1,699 of 1,838 qualifying container ships by EEOI, at the 92nd percentile. The dashed line is the type median, 14.2; this vessel reported 41.1.
EEOI divides emissions by transport work, which for this vessel and year was 225,382,611 tonne-miles over 40,306 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 34.8% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 19.0% while distance sailed rose 21.9%and CO₂ per nautical mile fell 2.4%.That points mainly to how much the vessel sailed, rather than the other.
