MSC REET II against its type

Built in 2002, it is 6 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 18,334 gross tonnage it is smaller than 77% 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 101 other vessels here, 74 of them container ships. Its MRV returns name it OKEE ANN MARI for 2018–2019 and MSC REET II for 2023–2025. The returns for 2018–2025 all give Monrovia as port of registry.

Its 8,019 t of CO₂ for 2025 is 51% 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 268.4 kg CO₂, 51% below the type median of 545.6 kg. It logged 3,537 hours at sea against a median of 3,155 hours for its type that year. 7.6% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 5 years with reported emissions, the highest was 2018 (12,152 t) and the lowest 2023 (1,620 t). Its efficiency percentile within the type went from 79 in 2018 to 78 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2025

Position 1,437 of 1,838 qualifying container ships by EEOI, at the 78th percentile. The dashed line is the type median, 14.2; this vessel reported 24.6.

EEOI divides emissions by transport work, which for this vessel and year was 326,636,660 tonne-miles over 29,881 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 34.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, so the series has gaps.

From 2024 to 2025, emissions fell 17.7% while distance sailed fell 4.4%and CO₂ per nautical mile fell 13.9%.That points mainly to how efficiently it sailed, rather than the other.
