MANISA ALENA 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). It is one of 187 general cargo ships here under the Portugal flag, 6.1% of the 3,081 on the register. Its MRV returns name it SIDER MANZANILLO for 2018, MANISA ALENA for 2019–2021 and OSLO BULK 11 for 2022. The returns for 2018–2022 all give Madeira as port of registry.
Its 2,180 t of CO₂ for 2022 is 44% 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 141.6 kg CO₂, 27% below the type median of 193.6 kg. It logged 1,639 hours at sea against a median of 1,979 hours for its type that year. 7.2% of its 2022 emissions were at berth; the median for general cargo ships was 4.3%. Across 5 years with reported emissions, the highest was 2021 (5,592 t) and the lowest 2022 (2,180 t). Its efficiency percentile within the type went from 62 in 2018 to 0 in 2019 (lower is more efficient).

Efficiency against its own type2019
Position 1 of 381 qualifying general cargo ships by EEOI, at the 0th percentile. The dashed line is the type median, 28.8; this vessel reported 4.7.
EEOI divides emissions by transport work, which for this vessel and year was 1,187,430,704 tonne-miles over 33,762 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2022 was 60.4% lower than in 2018, for EU/EEA voyages only.
From 2021 to 2022, emissions fell 61.0% and CO₂ per nautical mile fell 6.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
