CS CALVINA against its type
It is one of 218 bulk carriers here under the Bahamas flag, 2.7% of the 8,138 on the register. The returns for 2018–2025 all give NASSAU as port of registry.
Its 1,798 t of CO₂ for 2025 is 44% below the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 227.7 kg CO₂, 13% below the type median of 260.7 kg. It logged 1,054 hours at sea against a median of 1,200 hours for its type that year. 4.6% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 7 years with reported emissions, the highest was 2020 (9,900 t) and the lowest 2025 (1,798 t). Its efficiency percentile within the type went from 57 in 2018 to 52 in 2025 (lower is more efficient). Of the 3 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,682 of 3,241 qualifying bulk carriers by EEOI, at the 52nd percentile. The dashed line is the type median, 7.6; this vessel reported 7.7.
EEOI divides emissions by transport work, which for this vessel and year was 233,242,542 tonne-miles over 7,897 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 81.8% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions fell 29.3% while distance sailed fell 26.6%and CO₂ per nautical mile fell 3.7%.That points mainly to how much the vessel sailed, rather than the other.
