ECO DIAGON ALLEY against its type

Built in 2012, it is the same age as the median bulk carrier on this register (build year 2012, 6,882 vessels with a known build year). At 42,713 gross tonnage it is larger than 67% of the other 6,571 bulk carriers with a recorded tonnage. 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 PATRA for 2018–2023 and ECO DIAGON ALLEY for 2025. The reported port of registry changed: PIRAEUS (2019–2023), then MONROVIA (2025).

Its 4,284 t of CO₂ for 2023 is 27% above the median of 3,386 t among the 3,573 bulk carriers on this register that reported for 2023. Per nautical mile it emitted 263.9 kg CO₂, close to the type median of 272.6 kg. It logged 1,417 hours at sea against a median of 1,186 hours for its type that year. 1.7% of its 2023 emissions were at berth; the median for bulk carriers was 4.3%. Across 5 years with reported emissions, the highest was 2021 (7,287 t) and the lowest 2018 (808 t). Its efficiency percentile within the type went from 88 in 2019 to 8 in 2023 (lower is more efficient). The one comparable vessel listed below with a 2023 return reported a higher or equal CO₂ per nautical mile.

No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2023

Position 277 of 3,262 qualifying bulk carriers by EEOI, at the 8th percentile. The dashed line is the type median, 8.0; this vessel reported 4.6.

EEOI divides emissions by transport work, which for this vessel and year was 933,259,259 tonne-miles over 16,231 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2023 was 430.2% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2024, so the series has gaps.

From 2022 to 2023, emissions fell 20.7% while distance sailed fell 12.5%and CO₂ per nautical mile fell 9.3%.
