ID PIONEER against its type
Built in 2012, it is the same age as the median bulk carrier on this register (build year 2012, 6,882 vessels with a known build year). At 23,883 gross tonnage it is smaller than 80% 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 11 other vessels here, 9 of them bulk carriers. Its MRV returns name it ID PIONEER for 2018–2024 and WEST HARMONY for 2025. The reported port of registry changed: Valletta (2022–2024), then Monrovia (2025).
Its 5,056 t of CO₂ for 2025 is 1.6 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 236.7 kg CO₂, close to the type median of 260.7 kg. It logged 1,950 hours at sea against a median of 1,200 hours for its type that year. 4.8% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 6 years with reported emissions, the highest was 2025 (5,056 t) and the lowest 2021 (1,280 t). Its efficiency percentile within the type went from 70 in 2019 to 81 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 2,630 of 3,241 qualifying bulk carriers by EEOI, at the 81st percentile. The dashed line is the type median, 7.6; this vessel reported 10.6.
EEOI divides emissions by transport work, which for this vessel and year was 476,124,294 tonne-miles over 21,360 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 72.9% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions rose 172.2% while distance sailed rose 185.8%and CO₂ per nautical mile fell 4.8%.That points mainly to how much the vessel sailed, rather than the other.
