COLUMBIA RIVER against its type

Built in 2006, it is 6 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). It is one of 637 bulk carriers here under the Hong Kong flag, 7.8% of the 8,138 on the register. The same builder is recorded for 83 other vessels here, 71 of them bulk carriers. The reported port of registry changed: Hong Kong (2020), then Hong Kong, China (2023–2025).

Its 2,856 t of CO₂ for 2025 is 12% below the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 299.6 kg CO₂, 15% above the type median of 260.7 kg. It logged 961 hours at sea against a median of 1,200 hours for its type that year. 3.6% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 4 years with reported emissions, the highest was 2020 (8,185 t) and the lowest 2023 (1,064 t). Its efficiency percentile within the type went from 48 in 2020 to 83 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 2,682 of 3,241 qualifying bulk carriers by EEOI, at the 83rd percentile. The dashed line is the type median, 7.6; this vessel reported 10.9.

EEOI divides emissions by transport work, which for this vessel and year was 262,220,386 tonne-miles over 9,530 nautical miles.

Reported CO₂ in 2025 was 65.1% lower than in 2020, for EU/EEA voyages only. No return is recorded for 2021, 2022, so the series has gaps.

From 2024 to 2025, emissions fell 19.6% while distance sailed fell 25.4%and CO₂ per nautical mile rose 7.9%.That points mainly to how much the vessel sailed, rather than the other.
