GENIUS STAR XII against its type
It is one of 310 general cargo ships here under the Panama flag, 10.1% of the 3,081 on the register. Its MRV returns name it GENIUS STAR XII for 2018–2024 and KSL AMARA for 2025. The returns for 2018–2025 all give PANAMA as port of registry.
Its 3,315 t of CO₂ for 2025 is 18% above the median of 2,820 t among the 2,469 general cargo ships on this register that reported for 2025. Per nautical mile it emitted 161.2 kg CO₂, 32% above the type median of 122.2 kg. It logged 2,064 hours at sea against a median of 3,044 hours for its type that year. 3.7% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 5 years with reported emissions, the highest was 2018 (4,368 t) and the lowest 2024 (311 t). Its efficiency percentile within the type went from 94 in 2018 to 29 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 138 of 479 qualifying general cargo ships by EEOI, at the 29th percentile. The dashed line is the type median, 29.4; this vessel reported 23.6.
EEOI divides emissions by transport work, which for this vessel and year was 140,172,516 tonne-miles over 20,569 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 24.1% lower 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 966.0% and CO₂ per nautical mile rose 21.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
