ELKA DELOS against its type
Built in 2005, it is 5 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 27,612 gross tonnage it is larger than 65% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 402 chemical tankers here under the Liberia flag, 17.2% of the 2,344 on the register. The same builder is recorded for 56 other vessels here, 10 of them chemical tankers. The reported port of registry changed: Piraeus (2019), then Monrovia (2020–2025).
Its 9,248 t of CO₂ for 2025 is 1.7 times the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 332.6 kg CO₂, 33% above the type median of 250.2 kg. It logged 2,351 hours at sea against a median of 2,106 hours for its type that year. 5.6% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2024 (11,408 t) and the lowest 2023 (1,016 t). Its efficiency percentile within the type went from 61 in 2019 to 29 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2025
Position 392 of 1,348 qualifying chemical tankers by EEOI, at the 29th percentile. The dashed line is the type median, 14.4; this vessel reported 10.8.
EEOI divides emissions by transport work, which for this vessel and year was 853,101,476 tonne-miles over 27,801 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 39.3% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.
From 2024 to 2025, emissions fell 18.9% while distance sailed fell 28.9%and CO₂ per nautical mile rose 14.1%.That points mainly to how much the vessel sailed, rather than the other.
