JOHANNA 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 2,199 t of CO₂ for 2025 is 32% below the median of 3,238 t among the 3,732 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 281.6 kg CO₂, close to the type median of 260.7 kg. It logged 642 hours at sea against a median of 1,199 hours for its type that year. 11.5% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 8 years with reported emissions, the highest was 2021 (8,614 t) and the lowest 2025 (2,199 t). Its efficiency percentile within the type went from 95 in 2018 to 98 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 3,193 of 3,241 qualifying bulk carriers by EEOI, at the 98th percentile. The dashed line is the type median, 7.6; this vessel reported 21.1.
EEOI divides emissions by transport work, which for this vessel and year was 104,301,708 tonne-miles over 7,807 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 44.2% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 57.5% while distance sailed fell 61.3%and CO₂ per nautical mile rose 9.7%.That points mainly to how much the vessel sailed, rather than the other.
