RAINBOW LUCKY against its type
Built in 2010, it is 3 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 22,070 gross tonnage it is larger than 84% 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 RAINBOW LUCKY for 2018–2019 and SATURN J for 2025. The reported port of registry changed: Panama (2019), then BasseterreL (2025).
Its 2,437 t of CO₂ for 2025 is 14% below the median of 2,820 t among the 2,469 general cargo ships on this register that reported for 2025. Per nautical mile it emitted 214.1 kg CO₂, 1.8 times the type median of 122.2 kg. It logged 943 hours at sea against a median of 3,044 hours for its type that year. 1.8% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Of the 5 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 9.4% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, 2023, 2024, so the series has gaps.
From 2019 to 2025, emissions fell 9.4% and CO₂ per nautical mile fell 39.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
