MAPLE HARBOUR against its type
Built in 2011, it is 1 year older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 31,540 gross tonnage it is smaller than 67% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 26 bulk carriers here under the South Korea flag, 0.3% of the 8,138 on the register. The same builder is recorded for 87 other vessels here, 60 of them bulk carriers. Its MRV returns name it KURE HARBOUR for 2018 and MAPLE HARBOUR for 2022–2025. The reported port of registry changed: PANAMA (2018), then JEJU (2022–2025).
Its 3,719 t of CO₂ for 2025 is 15% above the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 247.7 kg CO₂, close to the type median of 260.7 kg. It logged 1,341 hours at sea against a median of 1,200 hours for its type that year. 1.1% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 5 years with reported emissions, the highest was 2023 (6,153 t) and the lowest 2018 (1,149 t). Its efficiency percentile within the type went from 45 in 2022 to 35 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,143 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 562,689,864 tonne-miles over 15,014 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 223.8% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, so the series has gaps.
From 2024 to 2025, emissions rose 42.7% while distance sailed rose 67.8%and CO₂ per nautical mile fell 15.0%.That points mainly to how much the vessel sailed, rather than the other.
