ISABELLE G against its type

Built in 2004, it is 8 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 22,792 gross tonnage it is smaller than 84% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 157 bulk carriers here under the Portugal flag, 1.9% of the 8,138 on the register. The returns for 2018–2025 all give Madeira as port of registry.

Its 5,666 t of CO₂ for 2025 is 1.7 times the median of 3,238 t among the 3,732 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 227.0 kg CO₂, 13% below the type median of 260.7 kg. It logged 2,251 hours at sea against a median of 1,199 hours for its type that year. 3.6% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 8 years with reported emissions, the highest was 2020 (14,807 t) and the lowest 2019 (1,858 t). Its efficiency percentile within the type went from 86 in 2018 to 89 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 73.8% higher than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 17.5% while distance sailed rose 27.6%and CO₂ per nautical mile fell 7.9%.That points mainly to how much the vessel sailed, rather than the other.
