SIDER ATHENA against its type
Built in 2013, it is 1 year newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 24,785 gross tonnage it is smaller than 76% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 1,601 bulk carriers here under the Panama flag, 19.7% of the 8,138 on the register. The same builder is recorded for 114 other vessels here, 111 of them bulk carriers. Its MRV returns name it WUCHANG for 2018–2021 and SIDER ATHENA for 2022–2025. The reported port of registry changed: Hong Kong (2018–2021), then Panama (2022–2025).
Its 5,881 t of CO₂ for 2025 is 1.8 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 226.3 kg CO₂, 13% below the type median of 260.7 kg. It logged 2,440 hours at sea against a median of 1,200 hours for its type that year. 7.0% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 8 years with reported emissions, the highest was 2024 (8,189 t) and the lowest 2023 (674 t). Its efficiency percentile within the type went from 9 in 2018 to 42 in 2025 (lower is more efficient). Of the 3 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 1,353 of 3,241 qualifying bulk carriers by EEOI, at the 42nd percentile. The dashed line is the type median, 7.6; this vessel reported 7.1.
EEOI divides emissions by transport work, which for this vessel and year was 832,961,756 tonne-miles over 25,983 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 86.8% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 28.2% while distance sailed fell 30.0%and CO₂ per nautical mile rose 2.6%.That points mainly to how much the vessel sailed, rather than the other.
