ASTELLA 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 43 chemical tankers here under the Italy flag, 1.8% 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 ASTELLA for 2018–2023 and VALDERICE for 2024–2025. The reported port of registry changed: marseille (2018–2023), then Trieste (2024–2025).
Its 10,130 t of CO₂ for 2025 is 1.8 times the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 355.0 kg CO₂, 42% above the type median of 250.2 kg. It logged 2,621 hours at sea against a median of 2,109 hours for its type that year. 29.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2020 (12,882 t) and the lowest 2019 (4,239 t). Its efficiency percentile within the type went from 70 in 2019 to 78 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,053 of 1,348 qualifying chemical tankers by EEOI, at the 78th percentile. The dashed line is the type median, 14.4; this vessel reported 25.1.
EEOI divides emissions by transport work, which for this vessel and year was 403,761,260 tonne-miles over 28,535 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 12.3% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 12.9% while distance sailed fell 20.1%and CO₂ per nautical mile rose 9.0%.That points mainly to how much the vessel sailed, rather than the other.
