JUPITER N 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). At 51,239 gross tonnage it is larger than 85% 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 65 other vessels here, 44 of them bulk carriers. Its MRV returns name it JUPITER N for 2018–2022 and W-NAUTILUS for 2024–2025. The returns for 2018–2025 all give Monrovia as port of registry.

Its 7,850 t of CO₂ for 2022 is 2.0 times the median of 3,908 t among the 3,902 bulk carriers on this register that reported for 2022. Per nautical mile it emitted 352.7 kg CO₂, 22% above the type median of 288.1 kg. It logged 2,192 hours at sea against a median of 1,254 hours for its type that year. 3.2% of its 2022 emissions were at berth; the median for bulk carriers was 4.2%. Across 4 years with reported emissions, the highest was 2019 (9,320 t) and the lowest 2020 (2,375 t). Its efficiency percentile within the type went from 28 in 2018 to 46 in 2022 (lower is more efficient).

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 type2022

Position 1,687 of 3,692 qualifying bulk carriers by EEOI, at the 46th percentile. The dashed line is the type median, 8.4; this vessel reported 8.1.

EEOI divides emissions by transport work, which for this vessel and year was 966,726,601 tonne-miles over 22,255 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2022 was 46.1% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2023, so the series has gaps.

From 2020 to 2022, emissions rose 230.5% while distance sailed rose 213.1%and CO₂ per nautical mile rose 5.6%.That points mainly to how much the vessel sailed, rather than the other.
