CHEMSTAR RIVER against its type
Built in 2017, it is 7 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 13,098 gross tonnage it is smaller than 65% 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 same builder is recorded for 307 other vessels here, 98 of them chemical tankers. The returns for 2018–2024 all give PANAMA as port of registry.
Its 4,985 t of CO₂ for 2024 is 15% below the median of 5,830 t among the 1,451 chemical tankers on this register that reported for 2024. Per nautical mile it emitted 174.1 kg CO₂, 31% below the type median of 253.5 kg. It logged 2,836 hours at sea against a median of 2,177 hours for its type that year. 0.0% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Across 7 years with reported emissions, the highest was 2018 (10,665 t) and the lowest 2022 (3,340 t). Its efficiency percentile within the type went from 30 in 2018 to 71 in 2024 (lower is more efficient). Of the 2 sister ships listed below with a 2024 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 849 of 1,194 qualifying chemical tankers by EEOI, at the 71st percentile. The dashed line is the type median, 15.9; this vessel reported 23.5.
EEOI divides emissions by transport work, which for this vessel and year was 212,203,065 tonne-miles over 28,631 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 53.3% lower than in 2018, for EU/EEA voyages only.
From 2023 to 2024, emissions fell 29.8% while distance sailed fell 32.4%and CO₂ per nautical mile rose 3.8%.That points mainly to how much the vessel sailed, rather than the other.
