SAN ALFONSO 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 22,914 gross tonnage it is smaller than 74% of the other 3,000 container ships with a recorded tonnage. It is one of 976 container ships here under the Liberia flag, 27.9% of the 3,495 on the register. The same builder is recorded for 983 other vessels here, 86 of them container ships. CPO Containerschiffreederei is linked to 60 vessels on this register. The returns for 2022–2025 all give Monrovia as port of registry.
Its 4,479 t of CO₂ for 2025 is 73% 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 334.2 kg CO₂, 39% below the type median of 545.6 kg. It logged 1,236 hours at sea against a median of 3,155 hours for its type that year. 8.1% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 4 years with reported emissions, the highest was 2023 (18,138 t) and the lowest 2025 (4,479 t). Its efficiency percentile within the type went from 97 in 2022 to 83 in 2024 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 48.4% lower than in 2022, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 74.2% and CO₂ per nautical mile fell 9.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
