YM JUPITER against its type

Built in 2007, it is 3 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 10,917 gross tonnage it is smaller than 80% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 218 chemical tankers here under the Malta flag, 9.3% of the 2,344 on the register. The returns for 2018–2025 all give Valletta as port of registry.

Its 5,264 t of CO₂ for 2025 is close to the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 239.8 kg CO₂, close to the type median of 250.2 kg. It logged 2,264 hours at sea against a median of 2,106 hours for its type that year. 16.2% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2022 (10,379 t) and the lowest 2021 (3,433 t). Its efficiency percentile within the type went from 84 in 2018 to 87 in 2025 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,175 of 1,348 qualifying chemical tankers by EEOI, at the 87th percentile. The dashed line is the type median, 14.4; this vessel reported 33.5.

EEOI divides emissions by transport work, which for this vessel and year was 157,176,471 tonne-miles over 21,955 nautical miles.

Reported CO₂ by year

2018: 5,263 t20185,2632019: 9,321 t20192021: 3,433 t20212022: 10,379 t20222023: 7,227 t20232024: 8,934 t20242025: 5,264 t20255,264

Reported CO₂ in 2025 was <0.1% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.

From 2024 to 2025, emissions fell 41.1% while distance sailed fell 37.4%and CO₂ per nautical mile fell 5.9%.That points mainly to how much the vessel sailed, rather than the other.

Sources and how to read this

This page draws on 7 MRV reporting years, an efficiency ranking and 4 of 5 vessel particulars. Not found in the sources for this vessel: AIS movements in Norwegian waters, a name history, a licensed photograph, a sanctions listing and US port state inspections.

Empty means unreported, never zero. How EEOI, distance, percentiles and sister ships are handled is explained under reading a vessel page. Something wrong? See corrections.
