STEEN against its type

Built in 2008, it is the same age as the median container ship on this register (build year 2008, 3,088 vessels with a known build year). At 7,950 gross tonnage it is smaller than 96% 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 30 other vessels here, 6 of them container ships. The reported port of registry changed: Limassol (2019–2022), then Madeira (2023–2025).

Its 6,147 t of CO₂ for 2025 is 62% 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 275.9 kg CO₂, 49% below the type median of 545.6 kg. It logged 2,103 hours at sea against a median of 3,155 hours for its type that year. 4.3% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2022 (17,065 t) and the lowest 2025 (6,147 t). Its efficiency percentile within the type went from 90 in 2018 to 97 in 2023 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 25.3% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 42.0% and CO₂ per nautical mile rose 5.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
