AL RIFFA against its type
Built in 2012, it is 4 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 141,077 gross tonnage it is larger than 86% 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 563 other vessels here, 243 of them container ships. The reported port of registry changed: Valletta (2019–2022), then Monrovia (2023–2025).
Its 37,632 t of CO₂ for 2025 is 2.3 times the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 791.2 kg CO₂, 45% above the type median of 545.6 kg. It logged 3,214 hours at sea against a median of 3,155 hours for its type that year. 1.9% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 6 years with reported emissions, the highest was 2019 (43,759 t) and the lowest 2023 (4,342 t). Its efficiency percentile within the type went from 12 in 2019 to 14 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2025
Position 252 of 1,838 qualifying container ships by EEOI, at the 14th percentile. The dashed line is the type median, 14.2; this vessel reported 7.4.
EEOI divides emissions by transport work, which for this vessel and year was 5,057,998,656 tonne-miles over 47,563 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 14.0% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions rose 766.6% while distance sailed rose 1,179.0%and CO₂ per nautical mile fell 32.2%.That points mainly to how much the vessel sailed, rather than the other.
