SCA TUNADAL 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 11,550 gross tonnage it is smaller than 87% 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 44 other vessels here, 23 of them container ships. Its MRV returns name it SCA TUNADAL for 2018–2020 and TUNADAL for 2021–2025. The reported port of registry changed: Valletta (2018–2020), then Monrovia (2021–2025).

Its 12,392 t of CO₂ for 2025 is 24% 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 299.8 kg CO₂, 45% below the type median of 545.6 kg. It logged 3,501 hours at sea against a median of 3,155 hours for its type that year. 10.8% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2023 (18,081 t) and the lowest 2025 (12,392 t). Its efficiency percentile within the type went from 92 in 2018 to 94 in 2025 (lower is more efficient). Of the 8 sister ships listed below with a 2025 return, 8 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,731 of 1,838 qualifying container ships by EEOI, at the 94th percentile. The dashed line is the type median, 14.2; this vessel reported 44.2.

EEOI divides emissions by transport work, which for this vessel and year was 280,052,881 tonne-miles over 41,342 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 31.3% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 25.7% while distance sailed fell 25.0%and CO₂ per nautical mile fell 0.9%.That points mainly to how much the vessel sailed, rather than the other.
