ARIETTA LILY 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). At 43,006 gross tonnage it is larger than 68% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 1,589 bulk carriers here under the Liberia flag, 19.5% of the 8,138 on the register. The same builder is recorded for 360 other vessels here, 303 of them bulk carriers. The reported port of registry changed: Panama (2018), then Monrovia (2021–2025).
Its 7,440 t of CO₂ for 2025 is 2.3 times the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 250.1 kg CO₂, close to the type median of 260.7 kg. It logged 2,527 hours at sea against a median of 1,200 hours for its type that year. 2.2% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 6 years with reported emissions, the highest was 2025 (7,440 t) and the lowest 2018 (1,959 t). Its efficiency percentile within the type went from 54 in 2018 to 39 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2025
Position 1,274 of 3,241 qualifying bulk carriers by EEOI, at the 39th percentile. The dashed line is the type median, 7.6; this vessel reported 6.9.
EEOI divides emissions by transport work, which for this vessel and year was 1,082,967,977 tonne-miles over 29,743 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 279.8% 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 rose 52.1% while distance sailed rose 71.5%and CO₂ per nautical mile fell 11.3%.That points mainly to how much the vessel sailed, rather than the other.
