DIADEMA against its type
Built in 2018, it is 8 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 26,548 gross tonnage it is larger than 62% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 30 chemical tankers here under the Bahamas flag, 1.3% 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 2018–2024 all give NASSAU as port of registry.
Its 8,119 t of CO₂ for 2024 is 39% above the median of 5,830 t among the 1,451 chemical tankers on this register that reported for 2024. Per nautical mile it emitted 274.5 kg CO₂, close to the type median of 253.5 kg. It logged 2,892 hours at sea against a median of 2,177 hours for its type that year. 11.1% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Across 7 years with reported emissions, the highest was 2023 (10,028 t) and the lowest 2021 (4,810 t). Its efficiency percentile within the type went from 30 in 2018 to 38 in 2024 (lower is more efficient). The one sister ship listed below with a 2024 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2024
Position 459 of 1,194 qualifying chemical tankers by EEOI, at the 38th percentile. The dashed line is the type median, 15.9; this vessel reported 13.2.
EEOI divides emissions by transport work, which for this vessel and year was 612,721,509 tonne-miles over 29,580 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 1.9% lower than in 2018, for EU/EEA voyages only.
From 2023 to 2024, emissions fell 19.0% while distance sailed rose 6.2%and CO₂ per nautical mile fell 23.8%.That points mainly to how efficiently it sailed, rather than the other.
