CHEMSTAR IRIS against its type
Built in 2018, it is 8 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 12,238 gross tonnage it is smaller than 67% 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. The returns for 2018–2023 all give PANAMA as port of registry.
Its 6,131 t of CO₂ for 2023 is 14% above the median of 5,393 t among the 1,411 chemical tankers on this register that reported for 2023. Per nautical mile it emitted 197.3 kg CO₂, 24% below the type median of 258.0 kg. It logged 2,460 hours at sea against a median of 1,919 hours for its type that year. 5.3% of its 2023 emissions were at berth; the median for chemical tankers was 8.2%. Across 5 years with reported emissions, the highest was 2018 (7,772 t) and the lowest 2022 (3,019 t). Its efficiency percentile within the type went from 47 in 2018 to 28 in 2023 (lower is more efficient).

Efficiency against its own type2023
Position 349 of 1,230 qualifying chemical tankers by EEOI, at the 28th percentile. The dashed line is the type median, 15.6; this vessel reported 11.9.
EEOI divides emissions by transport work, which for this vessel and year was 516,488,627 tonne-miles over 31,076 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2023 was 21.1% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, so the series has gaps.
From 2022 to 2023, emissions rose 103.1% while distance sailed rose 107.3%and CO₂ per nautical mile fell 2.0%.That points mainly to how much the vessel sailed, rather than the other.
