WECO KAROLINE against its type
It is one of 1,601 bulk carriers here under the Panama flag, 19.7% of the 8,138 on the register. The returns for 2020–2025 all give PANAMA as port of registry.
Its 3,835 t of CO₂ for 2025 is 18% above the median of 3,238 t among the 3,732 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 190.4 kg CO₂, 27% below the type median of 260.7 kg. It logged 1,769 hours at sea against a median of 1,199 hours for its type that year. 2.1% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 6 years with reported emissions, the highest was 2021 (5,896 t) and the lowest 2024 (1,195 t). Its efficiency percentile within the type went from 64 in 2020 to 42 in 2025 (lower is more efficient). Of the 4 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 1,364 of 3,241 qualifying bulk carriers by EEOI, at the 42nd percentile. The dashed line is the type median, 7.6; this vessel reported 7.1.
EEOI divides emissions by transport work, which for this vessel and year was 542,463,932 tonne-miles over 20,142 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 71.5% higher than in 2020, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 220.9% and CO₂ per nautical mile rose 3.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
