AAL JUPITER against its type
Built in 2011, it is 4 years newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 22,863 gross tonnage it is larger than 85% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 216 general cargo ships here under the Liberia flag, 7.0% of the 3,081 on the register. Its MRV returns name it WARNOW JUPITER for 2018, AAL JUPITER for 2019–2021 and THE WHALE SHARK for 2022. The returns for 2018–2022 all give Monrovia as port of registry.
Its 2,690 t of CO₂ for 2022 is 31% below the median of 3,889 t among the 1,306 general cargo ships on this register that reported for 2022. Per nautical mile it emitted 321.1 kg CO₂, 1.7 times the type median of 193.6 kg. It logged 662 hours at sea against a median of 1,979 hours for its type that year. 23.8% of its 2022 emissions were at berth; the median for general cargo ships was 4.3%. Across 4 years with reported emissions, the highest was 2019 (6,332 t) and the lowest 2018 (2,628 t). Its efficiency percentile within the type went from 88 in 2018 to 28 in 2019 (lower is more efficient).

Efficiency against its own type2019
Position 108 of 381 qualifying general cargo ships by EEOI, at the 28th percentile. The dashed line is the type median, 28.8; this vessel reported 20.6.
EEOI divides emissions by transport work, which for this vessel and year was 306,620,823 tonne-miles over 22,388 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2022 was 2.4% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2021 to 2022, emissions fell 41.4% and CO₂ per nautical mile rose 19.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
