ATLANTIC HARMONY against its type
Built in 2017, it is 7 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,256 gross tonnage it is larger than 69% 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. The returns for 2020–2024 all give Majuro as port of registry.
Its 8,699 t of CO₂ for 2024 is 49% above the median of 5,830 t among the 1,451 chemical tankers on this register that reported for 2024. Per nautical mile it emitted 245.3 kg CO₂, close to the type median of 253.5 kg. It logged 3,072 hours at sea against a median of 2,177 hours for its type that year. 7.2% 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 (8,699 t) and the lowest 2023 (2,020 t). Its efficiency percentile within the type went from 2 in 2020 to 5 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 62 of 1,194 qualifying chemical tankers by EEOI, at the 5th percentile. The dashed line is the type median, 15.9; this vessel reported 7.5.
EEOI divides emissions by transport work, which for this vessel and year was 1,166,138,070 tonne-miles over 35,467 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 198.0% higher than in 2020, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.
From 2023 to 2024, emissions rose 330.7% while distance sailed rose 282.4%and CO₂ per nautical mile rose 12.6%.That points mainly to how much the vessel sailed, rather than the other.
