ELKA ASTIR against its type

Built in 2015, it is 5 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 31,905 gross tonnage it is larger than 98% 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 reported port of registry changed: Monrovia (2022–2023), then Valletta (2024–2025).

Its 5,485 t of CO₂ for 2025 is close to the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 278.4 kg CO₂, 11% above the type median of 250.2 kg. It logged 1,896 hours at sea against a median of 2,109 hours for its type that year. 9.5% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2024 (10,088 t) and the lowest 2022 (4,078 t). Its efficiency percentile within the type went from 47 in 2022 to 40 in 2025 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 538 of 1,348 qualifying chemical tankers by EEOI, at the 40th percentile. The dashed line is the type median, 14.4; this vessel reported 12.6.

Reported CO₂ in 2025 was 34.5% higher than in 2022, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 45.6% while distance sailed fell 37.8%and CO₂ per nautical mile fell 12.5%.That points mainly to how much the vessel sailed, rather than the other.
