ACQUA STELLA against its type
Built in 1999, it is 8 years older than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 6,352 gross tonnage it is larger than 50% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 310 general cargo ships here under the Panama flag, 10.1% of the 3,081 on the register. Its MRV returns name it DEFENDER for 2022–2024 and ACQUA STELLA for 2025. The reported port of registry changed: Bissau (2022–2024), then PANAMA (2025).
Its 1,246 t of CO₂ for 2025 is 56% 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 118.1 kg CO₂, close to the type median of 122.2 kg. It logged 1,095 hours at sea against a median of 3,044 hours for its type that year. 3.7% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 4 years with reported emissions, the highest was 2023 (2,685 t) and the lowest 2022 (1,187 t). Of the 6 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 146 of 479 qualifying general cargo ships by EEOI, at the 30th percentile. The dashed line is the type median, 29.4; this vessel reported 24.1.
EEOI divides emissions by transport work, which for this vessel and year was 51,814,969 tonne-miles over 10,550 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 5.0% higher than in 2022, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 44.2% and CO₂ per nautical mile rose 31.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
