AMIRA MARYANA against its type
Built in 2007, it is the same age as the median general cargo ship on this register (build year 2007, 2,852 vessels with a known build year). At 19,846 gross tonnage it is larger than 78% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 23 general cargo ships here under the San Marino flag, 0.7% 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 PALAWAN for 2018–2022 and AMIRA MARYANA for 2023–2025. The reported port of registry changed: Majuro (2018–2022), then San Marino (2023–2025).
Its 2,727 t of CO₂ for 2025 is close to 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 209.7 kg CO₂, 1.7 times the type median of 122.2 kg. It logged 1,375 hours at sea against a median of 3,044 hours for its type that year. 18.0% 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 2019 (5,788 t) and the lowest 2018 (1,500 t). Its efficiency percentile within the type went from 88 in 2019 to 24 in 2024 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 78 of 321 qualifying general cargo ships by EEOI, at the 24th percentile. The dashed line is the type median, 23.6; this vessel reported 15.5.
EEOI divides emissions by transport work, which for this vessel and year was 184,365,100 tonne-miles over 11,604 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 81.8% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2024 to 2025, emissions fell 4.8% and CO₂ per nautical mile fell 15.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
