CAS AMARES against its type
Built in 2011, it is 1 year older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). It is one of 1,589 bulk carriers here under the Liberia flag, 19.5% of the 8,138 on the register. The same builder is recorded for 77 other vessels here, 28 of them bulk carriers. Its MRV returns name it CAS AMARES for 2018–2019 and DISCOVERY for 2022–2025. The reported port of registry changed: Majuro (2019–2024), then Monrovia (2025).
Its 1,502 t of CO₂ for 2023 is 56% 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 302.9 kg CO₂, 11% above the type median of 272.6 kg. It logged 527 hours at sea against a median of 1,186 hours for its type that year. 5.0% of its 2023 emissions were at berth; the median for bulk carriers was 4.3%. Across 4 years with reported emissions, the highest was 2019 (2,524 t) and the lowest 2022 (1,345 t). Its efficiency percentile within the type went from 48 in 2018 to 56 in 2023 (lower is more efficient). The one sister ship listed below with a 2023 return reported a higher or equal CO₂ per nautical mile.
No EU/EEA voyages were reported for 2024, 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2023
Position 1,812 of 3,262 qualifying bulk carriers by EEOI, at the 56th percentile. The dashed line is the type median, 8.0; this vessel reported 8.4.
EEOI divides emissions by transport work, which for this vessel and year was 178,858,333 tonne-miles over 4,960 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2023 was 38.8% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, so the series has gaps.
From 2022 to 2023, emissions rose 11.7% while distance sailed rose 21.2%and CO₂ per nautical mile fell 7.8%.That points mainly to how much the vessel sailed, rather than the other.
