HARBIYE against its type
Built in 2008, it is 2 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 30,123 gross tonnage it is larger than 93% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 259 chemical tankers here under the Panama flag, 11.0% of the 2,344 on the register. Its MRV returns name it ISOLA CELESTE for 2018–2019, PS MILANO for 2020 and HARBIYE for 2023–2025. The reported port of registry changed: Valletta (2018–2019), then Genoa (2020), then Majuro (2023), then Panama (2024–2025).
Its 3,803 t of CO₂ for 2025 is 31% below the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 328.5 kg CO₂, 31% above the type median of 250.2 kg. It logged 1,834 hours at sea against a median of 2,106 hours for its type that year. 11.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2018 (11,093 t) and the lowest 2019 (1,899 t). Its efficiency percentile within the type went from 2 in 2018 to 64 in 2025 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 861 of 1,348 qualifying chemical tankers by EEOI, at the 64th percentile. The dashed line is the type median, 14.4; this vessel reported 18.2.
EEOI divides emissions by transport work, which for this vessel and year was 209,405,837 tonne-miles over 11,575 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 65.7% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2022, so the series has gaps.
From 2024 to 2025, emissions fell 13.1% while distance sailed fell 9.7%and CO₂ per nautical mile fell 3.8%.That points mainly to how much the vessel sailed, rather than the other.
