IGUAZU against its type
Built in 2017, it is 5 years newer 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 1,603 bulk carriers here under the Marshall Islands flag, 19.7% of the 8,138 on the register. The same builder is recorded for 95 other vessels here, 41 of them bulk carriers. Its MRV returns name it ZEPHYR VENTURE for 2018–2024 and IGUAZU for 2025. The reported port of registry changed: VALLETTA (2021–2024), then Majuro (2025).
Its 1,801 t of CO₂ for 2025 is 44% 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 268.8 kg CO₂, close to the type median of 260.7 kg. It logged 652 hours at sea against a median of 1,200 hours for its type that year. 1.0% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 6 years with reported emissions, the highest was 2024 (5,697 t) and the lowest 2021 (1,364 t). Its efficiency percentile within the type went from 30 in 2018 to 35 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,134 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 273,221,548 tonne-miles over 6,698 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 9.5% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, so the series has gaps.
From 2024 to 2025, emissions fell 68.4% while distance sailed fell 75.5%and CO₂ per nautical mile rose 29.0%.That points mainly to how much the vessel sailed, rather than the other.
