AM UMANG against its type
It is one of 1,589 bulk carriers here under the Liberia flag, 19.5% of the 8,138 on the register. Its MRV returns name it RICH WAVE for 2018 and AM UMANG for 2019–2023. The reported port of registry changed: PANAMA (2018), then MONROVIA (2019–2023).
Its 987 t of CO₂ for 2023 is 71% below the median of 3,386 t among the 3,573 bulk carriers on this register that reported for 2023. Per nautical mile it emitted 333.9 kg CO₂, 23% above the type median of 272.6 kg. It logged 297 hours at sea against a median of 1,186 hours for its type that year. 10.1% of its 2023 emissions were at berth; the median for bulk carriers was 4.3%. Across 5 years with reported emissions, the highest was 2021 (12,435 t) and the lowest 2023 (987 t). Its efficiency percentile within the type went from 44 in 2018 to 19 in 2022 (lower is more efficient).

Efficiency against its own type2022
Position 694 of 3,692 qualifying bulk carriers by EEOI, at the 19th percentile. The dashed line is the type median, 8.4; this vessel reported 6.0.
EEOI divides emissions by transport work, which for this vessel and year was 2,073,523,490 tonne-miles over 44,491 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2023 was 64.6% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2022 to 2023, emissions fell 92.0% and CO₂ per nautical mile rose 20.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
