CALYPSO.GR against its type
It is one of 181 general cargo ships here under the Marshall Islands flag, 5.9% of the 3,081 on the register. The returns for 2019–2025 all give Majuro as port of registry.
Its 1,886 t of CO₂ for 2025 is 33% below 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 182.2 kg CO₂, 49% above the type median of 122.2 kg. It logged 947 hours at sea against a median of 3,044 hours for its type that year. 4.5% 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 2022 (6,218 t) and the lowest 2025 (1,886 t). Its efficiency percentile within the type went from 32 in 2019 to 55 in 2022 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2022
Position 2,042 of 3,692 qualifying bulk carriers by EEOI, at the 55th percentile. The dashed line is the type median, 8.4; this vessel reported 8.8.
EEOI divides emissions by transport work, which for this vessel and year was 702,550,282 tonne-miles over 28,754 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 61.4% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2023, 2024, so the series has gaps.
From 2022 to 2025, emissions fell 69.7% and CO₂ per nautical mile fell 15.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
