DAIWAN DOLPHIN against its type

Built in 2015, it is 3 years newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 21,525 gross tonnage it is smaller than 87% 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 same builder is recorded for 90 other vessels here, 68 of them bulk carriers. Its MRV returns name it DAIWAN DOLPHIN for 2020–2022 and EMERALD CONFIDENCE for 2024–2025. The reported port of registry changed: PANAMA (2020–2022), then MADEIRA (2024–2025).

Its 2,104 t of CO₂ for 2024 is 38% below the median of 3,377 t among the 3,676 bulk carriers on this register that reported for 2024. Per nautical mile it emitted 220.7 kg CO₂, 16% below the type median of 264.0 kg. It logged 913 hours at sea against a median of 1,238 hours for its type that year. 0.0% of its 2024 emissions were at berth; the median for bulk carriers was 2.9%. Across 3 years with reported emissions, the highest was 2024 (2,104 t) and the lowest 2020 (1,636 t). Its efficiency percentile within the type went from 74 in 2020 to 46 in 2022 (lower is more efficient). The one sister ship listed below with a 2024 return reported a lower 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 type2022

Position 1,692 of 3,692 qualifying bulk carriers by EEOI, at the 46th percentile. The dashed line is the type median, 8.4; this vessel reported 8.1.

EEOI divides emissions by transport work, which for this vessel and year was 204,153,752 tonne-miles over 8,261 nautical miles.

Reported CO₂ in 2024 was 28.6% higher than in 2020, for EU/EEA voyages only. No return is recorded for 2021, 2023, so the series has gaps.

From 2022 to 2024, emissions rose 26.7% and CO₂ per nautical mile rose 9.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
