JUPITER STAR against its type

Built in 2021, it is 11 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,537 gross tonnage it is larger than 76% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 402 chemical tankers here under the Liberia flag, 17.2% of the 2,344 on the register. The same builder is recorded for 983 other vessels here, 330 of them chemical tankers. The returns for 2022–2024 all give MONROVIA as port of registry.

Its 1,150 t of CO₂ for 2025 is 79% below the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 261.1 kg CO₂, close to the type median of 250.2 kg. It logged 401 hours at sea against a median of 2,109 hours for its type that year. 3.3% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2024 (10,079 t) and the lowest 2025 (1,150 t). Its efficiency percentile within the type went from 14 in 2022 to 4 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 50 of 1,348 qualifying chemical tankers by EEOI, at the 4th percentile. The dashed line is the type median, 14.4; this vessel reported 6.9.

Reported CO₂ in 2025 was 77.2% lower than in 2022, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 88.6% while distance sailed fell 88.5%and CO₂ per nautical mile fell 0.9%.That points mainly to how much the vessel sailed, rather than the other.
