CLIPPER ISABELLA against its type
It is one of 1,589 bulk carriers here under the Liberia flag, 19.5% of the 8,138 on the register. Its MRV returns name it CLIPPER ISABELLA for 2018, OCEAN ISABELLA for 2019 and PORT KOBE for 2023–2025. The reported port of registry changed: PANAMA (2018–2019), then Monrovia (2023–2025).
Its 570 t of CO₂ for 2025 is 82% 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 196.9 kg CO₂, 24% below the type median of 260.7 kg. It logged 333 hours at sea against a median of 1,200 hours for its type that year. 5.9% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 5 years with reported emissions, the highest was 2019 (8,332 t) and the lowest 2025 (570 t). Its efficiency percentile within the type went from 8 in 2018 to 14 in 2024 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 393 of 2,858 qualifying bulk carriers by EEOI, at the 14th percentile. The dashed line is the type median, 7.9; this vessel reported 5.2.
EEOI divides emissions by transport work, which for this vessel and year was 173,116,054 tonne-miles over 3,397 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 86.3% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, so the series has gaps.
From 2024 to 2025, emissions fell 36.3% and CO₂ per nautical mile fell 25.3%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
