AMBRA 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 12,899 gross tonnage it is larger than 70% 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. Its MRV returns name it AMBRA for 2018–2021 and LODESTAR WAY for 2025. The reported port of registry changed: VALLETTA (2018–2021), then Monrovia (2025).
Its 7,848 t of CO₂ for 2021 is 1.8 times the median of 4,268 t among the 1,316 general cargo ships on this register that reported for 2021. Per nautical mile it emitted 240.8 kg CO₂, 27% above the type median of 189.1 kg. It logged 3,061 hours at sea against a median of 2,017 hours for its type that year. 5.1% of its 2021 emissions were at berth; the median for general cargo ships was 3.9%. Across 4 years with reported emissions, the highest was 2019 (10,317 t) and the lowest 2018 (7,109 t). Its efficiency percentile within the type went from 32 in 2018 to 58 in 2021 (lower is more efficient).
No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2021
Position 188 of 326 qualifying general cargo ships by EEOI, at the 58th percentile. The dashed line is the type median, 22.6; this vessel reported 24.3.
EEOI divides emissions by transport work, which for this vessel and year was 322,691,201 tonne-miles over 32,585 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2021 was 10.4% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2022, 2023, 2024, so the series has gaps.
From 2020 to 2021, emissions fell 0.5% while distance sailed rose 2.3%and CO₂ per nautical mile fell 2.7%.
