AMSTEL CONFIDENCE against its type
Built in 2011, it is 4 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 24,020 gross tonnage it is larger than 91% 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 69 other vessels here, 3 of them general cargo ships. Its MRV returns name it AMSTEL CONFIDENCE for 2018–2023 and ATHENA SAN for 2025. The reported port of registry changed: Madeira (2018–2023), then Monrovia (2025).
Its 4,108 t of CO₂ for 2025 is 46% 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 242.3 kg CO₂, 2.0 times the type median of 122.2 kg. It logged 1,423 hours at sea against a median of 3,044 hours for its type that year. 0.0% 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 2021 (10,391 t) and the lowest 2023 (1,268 t). Its efficiency percentile within the type went from 63 in 2019 to 5 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 23 of 479 qualifying general cargo ships by EEOI, at the 5th percentile. The dashed line is the type median, 29.4; this vessel reported 10.8.
EEOI divides emissions by transport work, which for this vessel and year was 381,089,981 tonne-miles over 16,956 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 167.1% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions rose 223.9% while distance sailed rose 229.1%and CO₂ per nautical mile fell 1.6%.That points mainly to how much the vessel sailed, rather than the other.
