ATHENA CENTURY 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 43,248 gross tonnage it is larger than 72% 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 360 other vessels here, 303 of them bulk carriers. Its MRV returns name it BRIGHT GEMINI for 2018–2022 and ATHENA CENTURY for 2025. The returns for 2018–2025 all give PANAMA as port of registry.

Its 7,111 t of CO₂ for 2025 is 2.2 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 289.5 kg CO₂, 11% above the type median of 260.7 kg. It logged 2,302 hours at sea against a median of 1,200 hours for its type that year. 1.7% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 5 years with reported emissions, the highest was 2021 (7,561 t) and the lowest 2018 (4,460 t). Its efficiency percentile within the type went from 59 in 2018 to 22 in 2025 (lower is more efficient). Of the 2 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 717 of 3,241 qualifying bulk carriers by EEOI, at the 22nd percentile. The dashed line is the type median, 7.6; this vessel reported 5.7.

EEOI divides emissions by transport work, which for this vessel and year was 1,243,138,112 tonne-miles over 24,560 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 59.4% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2023, 2024, so the series has gaps.

From 2022 to 2025, emissions fell 2.7% while distance sailed rose 9.6%and CO₂ per nautical mile fell 11.2%.
