CHAMCHURI NAREE against its type
Built in 2005, it is 7 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). It is one of 17 bulk carriers here under the San Marino flag, 0.2% of the 8,138 on the register. Its MRV returns name it CHAMCHURI NAREE for 2019–2023 and MANSOUR M for 2025. The reported port of registry changed: Bangkok (2019–2022), then SINGAPORE (2023), then San Marino (2025).
Its 1,294 t of CO₂ for 2025 is 60% below the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 207.7 kg CO₂, 20% below the type median of 260.7 kg. It logged 545 hours at sea against a median of 1,200 hours for its type that year. 8.1% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 4 years with reported emissions, the highest was 2022 (5,696 t) and the lowest 2025 (1,294 t). Its efficiency percentile within the type went from 83 in 2019 to 81 in 2025 (lower is more efficient). Of the 2 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 2,627 of 3,241 qualifying bulk carriers by EEOI, at the 81st percentile. The dashed line is the type median, 7.6; this vessel reported 10.6.
EEOI divides emissions by transport work, which for this vessel and year was 121,954,760 tonne-miles over 6,231 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 37.4% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2024, so the series has gaps.
From 2023 to 2025, emissions fell 54.9% while distance sailed fell 52.4%and CO₂ per nautical mile fell 5.1%.That points mainly to how much the vessel sailed, rather than the other.
