BLUE UNION ALPHA: CO₂ emissions 2018–2025

BLUE UNION ALPHA 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). 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 323 other vessels here, 238 of them bulk carriers. Its MRV returns name it HINASE for 2018–2023 and BLUE UNION ALPHA for 2025. The reported port of registry changed: PANAMA (2018–2023), then Monrovia (2025).

Its 2,282 t of CO₂ for 2025 is 30% 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 194.2 kg CO₂, 26% below the type median of 260.7 kg. It logged 1,163 hours at sea against a median of 1,200 hours for its type that year. 9.1% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 6 years with reported emissions, the highest was 2021 (5,522 t) and the lowest 2019 (1,152 t). Its efficiency percentile within the type went from 81 in 2018 to 88 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 2,860 of 3,241 qualifying bulk carriers by EEOI, at the 88th percentile. The dashed line is the type median, 7.6; this vessel reported 12.2.

EEOI divides emissions by transport work, which for this vessel and year was 187,372,742 tonne-miles over 11,754 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 49.3% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2024, so the series has gaps.

From 2023 to 2025, emissions fell 53.5% while distance sailed fell 56.6%and CO₂ per nautical mile rose 7.1%.That points mainly to how much the vessel sailed, rather than the other.
