ANSAC GREEN RIVER against its type
Built in 2018, it is 11 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 21,198 gross tonnage it is larger than 82% 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 ANSAC GREEN RIVER for 2020 and ASTERIUS for 2025. The reported port of registry changed: PANAMA (2020), then majuro (2025).
Its 1,560 t of CO₂ for 2025 is 45% 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 185.1 kg CO₂, 1.5 times the type median of 122.2 kg. It logged 746 hours at sea against a median of 3,044 hours for its type that year. 2.8% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Of the 7 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2020
Position 2,108 of 2,985 qualifying bulk carriers by EEOI, at the 70th percentile. The dashed line is the type median, 8.1; this vessel reported 9.8.
EEOI divides emissions by transport work, which for this vessel and year was 196,791,455 tonne-miles over 10,459 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 19.3% lower than in 2020, for EU/EEA voyages only. No return is recorded for 2021, 2022, 2023, 2024, so the series has gaps.
From 2020 to 2025, emissions fell 19.3% and CO₂ per nautical mile rose 0.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
