CHEM SPARK against its type
Built in 2016, it is 6 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 16,084 gross tonnage it is smaller than 61% 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 76 other vessels here, 58 of them chemical tankers. Its MRV returns name it NAVIG8 SPARK for 2020, HAFNIA SPARK for 2021 and CHEM SPARK for 2022–2025. The returns for 2020–2025 all give Majuro as port of registry.
Its 8,070 t of CO₂ for 2025 is 46% above the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 220.6 kg CO₂, 12% below the type median of 250.2 kg. It logged 3,336 hours at sea against a median of 2,106 hours for its type that year. 5.8% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2025 (8,070 t) and the lowest 2022 (1,152 t). Its efficiency percentile within the type went from 24 in 2020 to 36 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 491 of 1,348 qualifying chemical tankers by EEOI, at the 36th percentile. The dashed line is the type median, 14.4; this vessel reported 12.1.
EEOI divides emissions by transport work, which for this vessel and year was 668,072,848 tonne-miles over 36,578 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 167.0% higher than in 2020, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 30.2% while distance sailed rose 11.1%and CO₂ per nautical mile rose 17.2%.That points mainly to how efficiently it sailed, rather than the other.
