ADFINES SUN 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 13,239 gross tonnage it is smaller than 64% 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 19 other vessels here, one of them a chemical tanker. Its MRV returns name it ADFINES SUN for 2019 and RF STELLA for 2020–2025. The returns for 2019–2025 all give Valletta as port of registry.
Its 1,509 t of CO₂ for 2024 is 74% 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 175.9 kg CO₂, 31% below the type median of 253.5 kg. It logged 728 hours at sea against a median of 2,177 hours for its type that year. 3.2% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Across 6 years with reported emissions, the highest was 2021 (8,689 t) and the lowest 2024 (1,509 t). Its efficiency percentile within the type went from 67 in 2019 to 51 in 2024 (lower is more efficient). The one sister ship listed below with a 2024 return reported a higher or equal CO₂ per nautical mile.
No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2024
Position 614 of 1,194 qualifying chemical tankers by EEOI, at the 51st percentile. The dashed line is the type median, 15.9; this vessel reported 16.3.
EEOI divides emissions by transport work, which for this vessel and year was 92,563,190 tonne-miles over 8,576 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 67.3% lower than in 2019, for EU/EEA voyages only.
From 2023 to 2024, emissions fell 68.1% while distance sailed fell 59.3%and CO₂ per nautical mile fell 21.6%.That points mainly to how much the vessel sailed, rather than the other.
