OPTIMA against its type
Built in 2000, it is 7 years older than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 6,204 gross tonnage it is smaller than 51% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 381 general cargo ships here under the Antigua and Barbuda flag, 12.4% of the 3,081 on the register. The same builder is recorded for 25 other vessels here, 7 of them general cargo ships. Its MRV returns name it REK MAJESTY for 2018–2021 and OPTIMA for 2022–2025. The reported port of registry changed: Panama (2018–2021), then Antigua and Barbuda (2022), then St. John's (2023–2025).
Its 4,647 t of CO₂ for 2025 is 1.6 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 145.7 kg CO₂, 19% above the type median of 122.2 kg. It logged 3,238 hours at sea against a median of 3,044 hours for its type that year. 2.2% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 8 years with reported emissions, the highest was 2022 (6,857 t) and the lowest 2018 (1,887 t). Its efficiency percentile within the type went from 59 in 2019 to 74 in 2023 (lower is more efficient). The one sister ship listed below with a 2025 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2023
Position 247 of 331 qualifying general cargo ships by EEOI, at the 74th percentile. The dashed line is the type median, 21.1; this vessel reported 32.0.
EEOI divides emissions by transport work, which for this vessel and year was 140,553,404 tonne-miles over 20,977 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 146.2% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 1.4% and CO₂ per nautical mile fell 1.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
