ADARA against its type
Built in 2011, it is 1 year newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 23,248 gross tonnage it is larger than 51% 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 same builder is recorded for 983 other vessels here, 330 of them chemical tankers. Its MRV returns name it ADARA for 2018–2024 and HTM GRENADIER for 2025. The reported port of registry changed: Marseille (2018–2024), then Valletta (2025).
Its 13,568 t of CO₂ for 2025 is 2.5 times the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 368.2 kg CO₂, 47% above the type median of 250.2 kg. It logged 3,537 hours at sea against a median of 2,106 hours for its type that year. 14.3% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2019 (14,939 t) and the lowest 2018 (5,264 t). Its efficiency percentile within the type went from 50 in 2019 to 64 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 857 of 1,348 qualifying chemical tankers by EEOI, at the 64th percentile. The dashed line is the type median, 14.4; this vessel reported 18.1.
EEOI divides emissions by transport work, which for this vessel and year was 748,792,494 tonne-miles over 36,848 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 157.7% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 7.7% while distance sailed fell 11.8%and CO₂ per nautical mile rose 4.7%.That points mainly to how much the vessel sailed, rather than the other.
