ADASUN against its type
Built in 2017, it is 10 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 21,530 gross tonnage it is larger than 83% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 216 general cargo ships here under the Liberia flag, 7.0% of the 3,081 on the register. The same builder is recorded for 109 other vessels here, 35 of them general cargo ships. Its MRV returns name it HELGA BULKER for 2019–2023 and ADASUN for 2024–2025. The reported port of registry changed: MAJURO (2019–2023), then MONROVIA (2024–2025).
Its 652 t of CO₂ for 2025 is 77% 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 175.9 kg CO₂, 44% above the type median of 122.2 kg. It logged 388 hours at sea against a median of 3,044 hours for its type that year. 7.9% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 7 years with reported emissions, the highest was 2019 (7,250 t) and the lowest 2025 (652 t). Its efficiency percentile within the type went from 38 in 2019 to 8 in 2023 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2023
Position 27 of 331 qualifying general cargo ships by EEOI, at the 8th percentile. The dashed line is the type median, 21.1; this vessel reported 8.8.
EEOI divides emissions by transport work, which for this vessel and year was 403,378,563 tonne-miles over 16,224 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 91.0% lower than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 62.1% and CO₂ per nautical mile fell 8.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
