ADASUN against its type
Built in 2009, it is 2 years newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). It is one of 18 general cargo ships here under the Italy flag, 0.6% of the 3,081 on the register. The same builder is recorded for 127 other vessels here, 52 of them general cargo ships. Its MRV returns name it ADASUN for 2018–2022 and SEVEN AMARANTA for 2023–2025. The reported port of registry changed: Monrovia (2018–2022), then Naples (2023–2025).
Its 4,665 t of CO₂ for 2025 is 1.7 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 140.3 kg CO₂, 15% above the type median of 122.2 kg. It logged 3,530 hours at sea against a median of 3,044 hours for its type that year. 15.4% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 8 years with reported emissions, the highest was 2021 (5,365 t) and the lowest 2022 (3,672 t). Its efficiency percentile within the type went from 91 in 2023 to 78 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 375 of 479 qualifying general cargo ships by EEOI, at the 78th percentile. The dashed line is the type median, 29.4; this vessel reported 39.2.
EEOI divides emissions by transport work, which for this vessel and year was 118,885,066 tonne-miles over 33,246 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 16.4% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 16.0% while distance sailed rose 14.5%and CO₂ per nautical mile rose 1.4%.That points mainly to how much the vessel sailed, rather than the other.
