At 24,140 gross tonnage it is larger than 91% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 381 general cargo ships here under the Antigua and Barbuda flag, 12.4% of the 3,081 on the register. Its MRV returns name it UBC TOKYO for 2023–2024 and POLARIS 1 for 2025.

Its 3,327 t of CO₂ for 2025 is 18% above 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 251.3 kg CO₂, 2.1 times the type median of 122.2 kg. It logged 1,412 hours at sea against a median of 3,044 hours for its type that year. 1.3% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 3 years with reported emissions, the highest was 2023 (3,580 t) and the lowest 2024 (1,353 t). Of the 4 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 7.1% lower than in 2023, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 145.8% and CO₂ per nautical mile fell 5.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
