DIONI against its type
Built in 2010, it is 2 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 32,287 gross tonnage it is smaller than 65% 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. Its MRV returns name it SANTA KATARINA for 2018–2019 and DIONI for 2020–2025. The reported port of registry changed: PANAMA (2018–2019), then Monrovia (2021), then Madeira (2024–2025).
Its 2,035 t of CO₂ for 2021 is 48% below the median of 3,945 t among the 3,342 bulk carriers on this register that reported for 2021. Per nautical mile it emitted 288.5 kg CO₂, close to the type median of 291.9 kg. It logged 684 hours at sea against a median of 1,190 hours for its type that year. 10.8% of its 2021 emissions were at berth; the median for bulk carriers was 3.8%. Across 4 years with reported emissions, the highest was 2018 (11,075 t) and the lowest 2021 (2,035 t). Its efficiency percentile within the type went from 39 in 2018 to 22 in 2021 (lower is more efficient). The one comparable vessel listed below with a 2021 return reported a higher or equal CO₂ per nautical mile.
No EU/EEA voyages were reported for 2024, 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2021
Position 712 of 3,276 qualifying bulk carriers by EEOI, at the 22nd percentile. The dashed line is the type median, 8.4; this vessel reported 6.3.
EEOI divides emissions by transport work, which for this vessel and year was 322,438,986 tonne-miles over 7,053 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2021 was 81.6% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2022, 2023, so the series has gaps.
From 2020 to 2021, emissions fell 54.6% while distance sailed fell 49.8%and CO₂ per nautical mile fell 9.7%.That points mainly to how much the vessel sailed, rather than the other.
