DIAVOLEZZA against its type
Built in 2016, it is 4 years newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 51,147 gross tonnage it is larger than 84% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 16 bulk carriers here under the Switzerland flag, 0.2% of the 8,138 on the register. The same builder is recorded for 77 other vessels here, 28 of them bulk carriers. The returns for 2018–2025 all give Basel as port of registry.
Its 2,943 t of CO₂ for 2025 is close to the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 321.3 kg CO₂, 23% above the type median of 260.7 kg. It logged 914 hours at sea against a median of 1,200 hours for its type that year. 1.2% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 4 years with reported emissions, the highest was 2021 (7,513 t) and the lowest 2022 (2,336 t). Its efficiency percentile within the type went from 10 in 2018 to 35 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,152 of 3,241 qualifying bulk carriers by EEOI, at the 35th percentile. The dashed line is the type median, 7.6; this vessel reported 6.6.
EEOI divides emissions by transport work, which for this vessel and year was 443,932,127 tonne-miles over 9,161 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 47.1% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2023, 2024, so the series has gaps.
From 2022 to 2025, emissions rose 26.0% while distance sailed rose 40.1%and CO₂ per nautical mile fell 10.1%.That points mainly to how much the vessel sailed, rather than the other.
