POLLUX against its type
Built in 2007, it is the same age as the median general cargo ship on this register (build year 2007, 2,852 vessels with a known build year). At 19,846 gross tonnage it is larger than 78% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 216 general cargo ships here under the Liberia flag, 7.0% of the 3,081 on the register. The same builder is recorded for 109 other vessels here, 35 of them general cargo ships. The returns for 2018–2025 all give Monrovia as port of registry.
Its 4,932 t of CO₂ for 2025 is 1.7 times the median of 2,820 t among the 2,469 general cargo ships on this register that reported for 2025. Per nautical mile it emitted 219.8 kg CO₂, 1.8 times the type median of 122.2 kg. It logged 2,156 hours at sea against a median of 3,044 hours for its type that year. 3.5% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 7 years with reported emissions, the highest was 2021 (6,674 t) and the lowest 2022 (2,344 t). Its efficiency percentile within the type went from 96 in 2018 to 76 in 2023 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2023
Position 2,497 of 3,262 qualifying bulk carriers by EEOI, at the 76th percentile. The dashed line is the type median, 8.0; this vessel reported 10.7.
EEOI divides emissions by transport work, which for this vessel and year was 265,717,757 tonne-miles over 14,259 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 4.9% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions rose 73.5% and CO₂ per nautical mile rose 10.3%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
