ASTREA against its type
Built in 2006, it is 4 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 25,431 gross tonnage it is larger than 60% 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. Its MRV returns name it ASTREA for 2018–2021 and STREA for 2022. The reported port of registry changed: Valletta (2018–2021), then Monrovia (2022).
Its 8,689 t of CO₂ for 2022 is 50% above the median of 5,807 t among the 1,486 chemical tankers on this register that reported for 2022. Per nautical mile it emitted 380.4 kg CO₂, 43% above the type median of 266.3 kg. It logged 3,813 hours at sea against a median of 1,995 hours for its type that year. 7.1% of its 2022 emissions were at berth; the median for chemical tankers was 8.6%. Across 5 years with reported emissions, the highest was 2020 (14,421 t) and the lowest 2018 (8,044 t). Its efficiency percentile within the type went from 42 in 2018 to 77 in 2022 (lower is more efficient). The one comparable vessel listed below with a 2022 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2022
Position 1,031 of 1,334 qualifying chemical tankers by EEOI, at the 77th percentile. The dashed line is the type median, 15.7; this vessel reported 24.6.
EEOI divides emissions by transport work, which for this vessel and year was 353,225,203 tonne-miles over 22,845 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2022 was 8.0% higher than in 2018, for EU/EEA voyages only.
From 2021 to 2022, emissions fell 34.1% while distance sailed fell 24.2%and CO₂ per nautical mile fell 13.1%.That points mainly to how much the vessel sailed, rather than the other.
