MARINER against its type
Built in 2009, it is 3 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 32,957 gross tonnage it is smaller than 61% of the other 6,571 bulk carriers with a recorded tonnage. 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 118 other vessels here, 105 of them bulk carriers. Its MRV returns name it MARINER for 2019–2022, MARINOR for 2023–2024 and YUAN XING RI ZHAO for 2025. The reported port of registry changed: Nassau (2019–2022), then Monrovia (2024–2025).
Its 3,186 t of CO₂ for 2025 is close to the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 324.9 kg CO₂, 25% above the type median of 260.7 kg. It logged 954 hours at sea against a median of 1,200 hours for its type that year. 6.1% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 5 years with reported emissions, the highest was 2019 (6,501 t) and the lowest 2024 (1,282 t). Its efficiency percentile within the type went from 67 in 2019 to 70 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 2,283 of 3,241 qualifying bulk carriers by EEOI, at the 70th percentile. The dashed line is the type median, 7.6; this vessel reported 9.2.
EEOI divides emissions by transport work, which for this vessel and year was 347,487,459 tonne-miles over 9,808 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 51.0% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2020, 2021, so the series has gaps.
From 2024 to 2025, emissions rose 148.5% while distance sailed rose 217.5%and CO₂ per nautical mile fell 21.7%.That points mainly to how much the vessel sailed, rather than the other.
