JUPITER against its type
Built in 2009, it is 1 year older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,967 gross tonnage it is larger than 87% 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 returns for 2018–2022 all give Monrovia as port of registry.
Its 5,574 t of CO₂ for 2022 is close to the median of 5,807 t among the 1,486 chemical tankers on this register that reported for 2022. Per nautical mile it emitted 264.7 kg CO₂, close to the type median of 266.3 kg. It logged 2,227 hours at sea against a median of 1,995 hours for its type that year. 10.4% of its 2022 emissions were at berth; the median for chemical tankers was 8.6%. Across 5 years with reported emissions, the highest was 2021 (17,097 t) and the lowest 2022 (5,574 t). Its efficiency percentile within the type was 36 in both 2018 and 2022. Of the 2 comparable vessels listed below with a 2022 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2022
Position 482 of 1,334 qualifying chemical tankers by EEOI, at the 36th percentile. The dashed line is the type median, 15.7; this vessel reported 13.1.
EEOI divides emissions by transport work, which for this vessel and year was 426,470,543 tonne-miles over 21,058 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2022 was 48.3% lower than in 2018, for EU/EEA voyages only.
From 2021 to 2022, emissions fell 67.4% while distance sailed fell 64.8%and CO₂ per nautical mile fell 7.4%.That points mainly to how much the vessel sailed, rather than the other.
