KOTA BAHAGIA against its type
Built in 2011, it is 4 years newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 18,189 gross tonnage it is larger than 76% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 216 general cargo ships here under the Liberia flag, 7.0% of the 3,081 on the register. The same builder is recorded for 146 other vessels here, 12 of them general cargo ships. Its MRV returns name it KOTA BAHAGIA for 2020 and MARIA JOSE for 2024–2025. The reported port of registry changed: Singapore (2020), then Monrovia (2024–2025).
Its 10,817 t of CO₂ for 2025 is 3.8 times 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 236.5 kg CO₂, 1.9 times the type median of 122.2 kg. It logged 4,002 hours at sea against a median of 3,044 hours for its type that year. 5.8% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 3 years with reported emissions, the highest was 2025 (10,817 t) and the lowest 2020 (5,356 t). Its efficiency percentile within the type went from 30 in 2020 to 89 in 2024 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 9 of 10 qualifying combination carriers by EEOI, at the 89th percentile. The dashed line is the type median, 24.4; this vessel reported 35.1.
EEOI divides emissions by transport work, which for this vessel and year was 159,567,891 tonne-miles over 24,863 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 102.0% higher than in 2020, for EU/EEA voyages only. No return is recorded for 2021, 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions rose 93.0% and CO₂ per nautical mile rose 4.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
