PRINCESS AYANA against its type
Built in 1991, it is 16 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 6,902 gross tonnage it is larger than 54% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 67 general cargo ships here under the Palau flag, 2.2% of the 3,081 on the register. Its MRV returns name it STELLAPRIMA for 2018–2020 and PRINCESS AYANA for 2023. The reported port of registry changed: Willemstad (2018–2020), then Malakal Harbor (2023).
Its 1,739 t of CO₂ for 2023 is 52% 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 190.6 kg CO₂, close to the type median of 193.7 kg. It logged 5,348 hours at sea against a median of 1,942 hours for its type that year. 22.9% of its 2023 emissions were at berth; the median for general cargo ships was 4.5%. Across 4 years with reported emissions, the highest was 2018 (6,159 t) and the lowest 2023 (1,739 t). Its efficiency percentile within the type went from 78 in 2018 to 64 in 2020 (lower is more efficient).

Reported CO₂ by year
Reported CO₂ in 2023 was 71.8% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2022, so the series has gaps.
From 2020 to 2023, emissions fell 64.8% and CO₂ per nautical mile rose 38.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
