ATLANTIC PRISM against its type
Built in 2019, it is 7 years newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 24,332 gross tonnage it is smaller than 77% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 1,603 bulk carriers here under the Marshall Islands flag, 19.7% of the 8,138 on the register. Its MRV returns name it ATLANTIC PRISM for 2019–2021 and SIDER MIRAMARE for 2024–2025. The reported port of registry changed: PANAMA (2019–2021), then Majuro (2024–2025).
Its 5,966 t of CO₂ for 2025 is 1.8 times the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 210.5 kg CO₂, 19% below the type median of 260.7 kg. It logged 2,686 hours at sea against a median of 1,200 hours for its type that year. 8.9% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 4 years with reported emissions, the highest was 2025 (5,966 t) and the lowest 2021 (1,077 t). Its efficiency percentile within the type went from 36 in 2019 to 59 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,919 of 3,241 qualifying bulk carriers by EEOI, at the 59th percentile. The dashed line is the type median, 7.6; this vessel reported 8.3.
EEOI divides emissions by transport work, which for this vessel and year was 721,429,262 tonne-miles over 28,342 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 243.1% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2020, 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions rose 28.4% while distance sailed rose 25.0%and CO₂ per nautical mile rose 2.7%.That points mainly to how much the vessel sailed, rather than the other.
