JOANNA against its type
Built in 1999, it is 9 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 16,802 gross tonnage it is smaller than 81% 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 80 other vessels here, 41 of them container ships. The returns for 2018–2024 all give Monrovia as port of registry.
Its 7,934 t of CO₂ for 2024 is 55% below the median of 17,769 t among the 2,101 container ships on this register that reported for 2024. Per nautical mile it emitted 314.7 kg CO₂, 40% below the type median of 528.5 kg. It logged 2,443 hours at sea against a median of 3,325 hours for its type that year. 8.4% of its 2024 emissions were at berth; the median for container ships was 2.8%. Across 7 years with reported emissions, the highest was 2018 (15,948 t) and the lowest 2022 (5,540 t). Its efficiency percentile within the type went from 100 in 2018 to 82 in 2024 (lower is more efficient). Of the 2 sister ships listed below with a 2024 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 1,365 of 1,661 qualifying container ships by EEOI, at the 82nd percentile. The dashed line is the type median, 15.4; this vessel reported 30.1.
EEOI divides emissions by transport work, which for this vessel and year was 264,010,649 tonne-miles over 25,209 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 50.3% lower than in 2018, for EU/EEA voyages only.
From 2023 to 2024, emissions fell 49.8% while distance sailed fell 50.1%and CO₂ per nautical mile rose 0.5%.That points mainly to how much the vessel sailed, rather than the other.
