AROYAT against its type
Built in 1997, it is 15 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 11,194 gross tonnage it is smaller than 98% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 29 bulk carriers here under the Palau flag, 0.4% of the 8,138 on the register. The same builder is recorded for 95 other vessels here, 64 of them bulk carriers. Its MRV returns name it MACHITIS for 2018–2020 and AROYAT for 2022–2025. The reported port of registry changed: Nassau (2018–2020), then Malakal Harbor (2022–2025).
Its 1,204 t of CO₂ for 2025 is 63% 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 195.2 kg CO₂, 25% below the type median of 260.7 kg. It logged 893 hours at sea against a median of 1,200 hours for its type that year. 5.2% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 7 years with reported emissions, the highest was 2022 (4,427 t) and the lowest 2024 (478 t). Its efficiency percentile within the type went from 98 in 2019 to 99 in 2022 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 72.3% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.
From 2024 to 2025, emissions rose 152.0% and CO₂ per nautical mile rose 30.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
