AZTECA against its type

Built in 2014, it is 2 years newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 24,247 gross tonnage it is smaller than 78% of the other 6,571 bulk carriers with a recorded tonnage. 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 160 other vessels here, 68 of them bulk carriers. The returns for 2018–2025 all give Majuro as port of registry.

Its 4,330 t of CO₂ for 2025 is 34% 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 232.2 kg CO₂, 11% below the type median of 260.7 kg. It logged 1,820 hours at sea against a median of 1,200 hours for its type that year. 1.7% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 6 years with reported emissions, the highest was 2022 (6,788 t) and the lowest 2018 (731 t). Its efficiency percentile within the type went from 59 in 2020 to 52 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,669 of 3,241 qualifying bulk carriers by EEOI, at the 52nd percentile. The dashed line is the type median, 7.6; this vessel reported 7.7.

EEOI divides emissions by transport work, which for this vessel and year was 564,578,879 tonne-miles over 18,652 nautical miles.

Reported CO₂ by year

2018: 731 t20187312020: 3,904 t20202021: 2,726 t20212022: 6,788 t20222024: 1,537 t20242025: 4,330 t20254,330

Reported CO₂ in 2025 was 492.1% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.

From 2024 to 2025, emissions rose 181.8% while distance sailed rose 178.3%and CO₂ per nautical mile rose 1.2%.That points mainly to how much the vessel sailed, rather than the other.
