DONG-A KRIOS 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 28,160 gross tonnage it is larger than 66% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 474 chemical tankers here under the Marshall Islands flag, 20.2% 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 DONG-A KRIOS for 2018 and EMMA GRACE for 2022–2024. The reported port of registry changed: Panama (2018), then Majuro (2022–2024).
Its 12,657 t of CO₂ for 2024 is 2.2 times the median of 5,830 t among the 1,451 chemical tankers on this register that reported for 2024. Per nautical mile it emitted 229.8 kg CO₂, close to the type median of 253.5 kg. It logged 4,612 hours at sea against a median of 2,177 hours for its type that year. 6.8% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Across 4 years with reported emissions, the highest was 2024 (12,657 t) and the lowest 2023 (3,446 t). Its efficiency percentile within the type went from 47 in 2018 to 8 in 2024 (lower is more efficient). The one sister ship listed below with a 2024 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2024
Position 100 of 1,194 qualifying chemical tankers by EEOI, at the 8th percentile. The dashed line is the type median, 15.9; this vessel reported 8.0.
EEOI divides emissions by transport work, which for this vessel and year was 1,578,201,995 tonne-miles over 55,091 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 32.0% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, so the series has gaps.
From 2023 to 2024, emissions rose 267.3% while distance sailed rose 404.7%and CO₂ per nautical mile fell 27.2%.That points mainly to how much the vessel sailed, rather than the other.
