K-RIVER against its type
Built in 1997, it is 11 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 6,362 gross tonnage it is smaller than 99% 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 7,172 t of CO₂ for 2025 is 56% 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 179.4 kg CO₂, 67% below the type median of 545.6 kg. It logged 4,146 hours at sea against a median of 3,155 hours for its type that year. 4.0% 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 (10,628 t) and the lowest 2020 (2,978 t). Its efficiency percentile within the type went from 97 in 2018 to 98 in 2023 (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.

Reported CO₂ by year
Reported CO₂ in 2025 was 32.5% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 9.4% and CO₂ per nautical mile fell 3.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
