AKACIA 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 11,171 t of CO₂ for 2025 is 32% 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 247.6 kg CO₂, 55% below the type median of 545.6 kg. It logged 3,966 hours at sea against a median of 3,155 hours for its type that year. 13.3% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 7 years with reported emissions, the highest was 2021 (12,303 t) and the lowest 2024 (3,185 t). Its efficiency percentile within the type went from 83 in 2018 to 90 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,655 of 1,838 qualifying container ships by EEOI, at the 90th percentile. The dashed line is the type median, 14.2; this vessel reported 37.5.
EEOI divides emissions by transport work, which for this vessel and year was 298,040,822 tonne-miles over 45,117 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 40.7% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions rose 250.7% and CO₂ per nautical mile rose 2.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
