AS EMMA against its type
Built in 2010, it is 2 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 40,351 gross tonnage it is smaller than 55% 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 127 other vessels here, 46 of them container ships. Its MRV returns name it SONGA CALABRIA for 2019–2020, AS EMMA for 2021–2022 and MSC BEIRA IV for 2023. The returns for 2019–2023 all give Monrovia as port of registry.
Its 13,986 t of CO₂ for 2023 is close to the median of 14,627 t among the 1,920 container ships on this register that reported for 2023. Per nautical mile it emitted 604.6 kg CO₂, 19% above the type median of 509.2 kg. It logged 1,662 hours at sea against a median of 2,716 hours for its type that year. 1.0% of its 2023 emissions were at berth; the median for container ships was 4.0%. Across 5 years with reported emissions, the highest was 2019 (31,086 t) and the lowest 2022 (13,486 t). Its efficiency percentile within the type was 54 in both 2019 and 2023.

Efficiency against its own type2023
Position 902 of 1,664 qualifying container ships by EEOI, at the 54th percentile. The dashed line is the type median, 17.4; this vessel reported 18.8.
EEOI divides emissions by transport work, which for this vessel and year was 745,101,225 tonne-miles over 23,131 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2023 was 55.0% lower than in 2019, for EU/EEA voyages only.
From 2022 to 2023, emissions rose 3.7% while distance sailed fell 2.0%and CO₂ per nautical mile rose 5.8%.That points mainly to how efficiently it sailed, rather than the other.
