LIBERTAS-H against its type
Built in 2007, it is 1 year older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 7,532 gross tonnage it is smaller than 97% 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 22 other vessels here, 6 of them container ships. The returns for 2018–2025 all give Madeira as port of registry.
Its 11,046 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 242.2 kg CO₂, 56% below the type median of 545.6 kg. It logged 4,385 hours at sea against a median of 3,155 hours for its type that year. 4.6% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2019 (16,906 t) and the lowest 2023 (6,295 t). Of the 2 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 10.0% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 17.3% and CO₂ per nautical mile fell 15.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
