QUEEN SARA against its type
Built in 1998, it is 9 years older than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 10,220 gross tonnage it is larger than 66% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 20 general cargo ships here under the Sierra Leone flag, 0.6% of the 3,081 on the register. The same builder is recorded for 24 other vessels here, 6 of them general cargo ships. The returns for 2018–2023 all give Freetown as port of registry.
Its 1,946 t of CO₂ for 2023 is 47% below the median of 3,650 t among the 1,342 general cargo ships on this register that reported for 2023. Per nautical mile it emitted 203.2 kg CO₂, close to the type median of 193.7 kg. It logged 1,748 hours at sea against a median of 1,942 hours for its type that year. 6.4% of its 2023 emissions were at berth; the median for general cargo ships was 4.5%. Across 6 years with reported emissions, the highest was 2018 (2,856 t) and the lowest 2019 (523 t). Its efficiency percentile within the type went from 32 in 2021 to 86 in 2023 (lower is more efficient).

Efficiency against its own type2023
Position 285 of 331 qualifying general cargo ships by EEOI, at the 86th percentile. The dashed line is the type median, 21.1; this vessel reported 40.1.
EEOI divides emissions by transport work, which for this vessel and year was 48,529,808 tonne-miles over 9,572 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2023 was 31.9% lower than in 2018, for EU/EEA voyages only.
From 2022 to 2023, emissions rose 13.4% while distance sailed fell 3.2%and CO₂ per nautical mile rose 17.1%.That points mainly to how efficiently it sailed, rather than the other.
