AURORA VEGA 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 23,456 gross tonnage it is smaller than 81% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 1,603 bulk carriers here under the Marshall Islands flag, 19.7% of the 8,138 on the register. The same builder is recorded for 180 other vessels here, 74 of them bulk carriers. Its MRV returns name it THOMAS C for 2018–2019, GRANDMA LILA for 2020–2024 and AURORA VEGA for 2025. The reported port of registry changed: Majuro (2018–2019), then Kingstown (2020–2024), then MAJURO (2025).
Its 4,766 t of CO₂ for 2025 is 47% above the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 257.0 kg CO₂, close to the type median of 260.7 kg. It logged 1,743 hours at sea against a median of 1,200 hours for its type that year. 7.1% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 5 years with reported emissions, the highest was 2020 (7,398 t) and the lowest 2024 (2,793 t). Its efficiency percentile within the type went from 54 in 2018 to 76 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 2,482 of 3,241 qualifying bulk carriers by EEOI, at the 76th percentile. The dashed line is the type median, 7.6; this vessel reported 9.9.
EEOI divides emissions by transport work, which for this vessel and year was 479,930,514 tonne-miles over 18,546 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 50.3% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions rose 70.6% while distance sailed rose 79.0%and CO₂ per nautical mile fell 4.7%.That points mainly to how much the vessel sailed, rather than the other.
