LEOPARD MOON against its type
Built in 2013, it is 3 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,939 gross tonnage it is larger than 86% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 43 chemical tankers here under the Italy flag, 1.8% of the 2,344 on the register. The same builder is recorded for 180 other vessels here, 53 of them chemical tankers. Its MRV returns name it LEOPARD MOON for 2018–2020 and VALLE LUNA for 2021–2025. The reported port of registry changed: Singapore (2018–2020), then Genova (2021–2025).
Its 7,900 t of CO₂ for 2025 is 43% above the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 336.0 kg CO₂, 34% above the type median of 250.2 kg. It logged 2,203 hours at sea against a median of 2,109 hours for its type that year. 17.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2019 (9,362 t) and the lowest 2022 (2,910 t). Its efficiency percentile within the type went from 12 in 2018 to 50 in 2025 (lower is more efficient). Of the 3 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 680 of 1,348 qualifying chemical tankers by EEOI, at the 50th percentile. The dashed line is the type median, 14.4; this vessel reported 14.5.
EEOI divides emissions by transport work, which for this vessel and year was 545,201,518 tonne-miles over 23,513 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 2.3% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2022 to 2025, emissions rose 171.5% while distance sailed rose 146.1%and CO₂ per nautical mile rose 10.3%.That points mainly to how much the vessel sailed, rather than the other.
