BLUE ONE 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 23,758 gross tonnage it is larger than 90% 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 983 other vessels here, 22 of them general cargo ships. Its MRV returns name it CIELO DI DUBLINO for 2018–2020 and BLUE ONE for 2022–2024. The reported port of registry changed: CAGLIARI (2018–2020), then Monrovia (2022–2024).
Its 6,893 t of CO₂ for 2024 is 1.7 times the median of 4,046 t among the 1,395 general cargo ships on this register that reported for 2024. Per nautical mile it emitted 245.6 kg CO₂, 31% above the type median of 187.0 kg. It logged 2,351 hours at sea against a median of 2,074 hours for its type that year. 3.2% of its 2024 emissions were at berth; the median for general cargo ships was 3.9%. Across 6 years with reported emissions, the highest was 2022 (8,696 t) and the lowest 2019 (2,509 t). Its efficiency percentile within the type went from 66 in 2018 to 81 in 2020 (lower is more efficient). Of the 3 sister ships listed below with a 2024 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2020
Position 2,433 of 2,985 qualifying bulk carriers by EEOI, at the 81st percentile. The dashed line is the type median, 8.1; this vessel reported 11.3.
EEOI divides emissions by transport work, which for this vessel and year was 626,152,078 tonne-miles over 26,906 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 102.5% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.
From 2023 to 2024, emissions rose 15.1% and CO₂ per nautical mile fell 5.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
