At 33,689 gross tonnage it is larger than 97% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 181 general cargo ships here under the Marshall Islands flag, 5.9% of the 3,081 on the register. Its MRV returns name it KAI XUAN for 2018–2021 and STAR TOSCANA for 2023–2025. The returns for 2018–2025 all give Majuro as port of registry.
Its 9,029 t of CO₂ for 2025 is 3.2 times 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 244.5 kg CO₂, 2.0 times the type median of 122.2 kg. It logged 3,346 hours at sea against a median of 3,044 hours for its type that year. 4.6% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 6 years with reported emissions, the highest was 2023 (9,067 t) and the lowest 2018 (1,389 t). Of the 5 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 549.9% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2022, so the series has gaps.
From 2024 to 2025, emissions rose 2.4% and CO₂ per nautical mile fell 3.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
