ATHENA 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 32,839 gross tonnage it is smaller than 61% 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 139 other vessels here, 125 of them bulk carriers. Star Shipping is linked to 22 vessels on this register. Its MRV returns name it STAR ATHENA for 2018 and ATHENA for 2022–2024. The reported port of registry changed: Bergen (2018), then Monrovia (2022–2024).
Its 2,231 t of CO₂ for 2024 is 34% below the median of 3,377 t among the 3,676 bulk carriers on this register that reported for 2024. Per nautical mile it emitted 396.8 kg CO₂, 1.5 times the type median of 264.0 kg. It logged 2,165 hours at sea against a median of 1,238 hours for its type that year. 3.8% of its 2024 emissions were at berth; the median for bulk carriers was 2.9%. Across 4 years with reported emissions, the highest was 2018 (6,893 t) and the lowest 2024 (2,231 t). Its efficiency percentile within the type went from 74 in 2018 to 50 in 2023 (lower is more efficient). Of the 2 sister ships listed below with a 2024 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2024 was 67.6% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, so the series has gaps.
From 2023 to 2024, emissions fell 66.9% and CO₂ per nautical mile rose 37.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
