ATLANTIC POLARIS against its type
Built in 2009, it is 1 year older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,266 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. Its MRV returns name it ATLANTIC POLARIS for 2018–2023 and SEAWAYS POLARIS for 2025. The reported port of registry changed: Hong Kong (2018–2023), then Majuro (2025).
Its 13,894 t of CO₂ for 2025 is 2.5 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 285.5 kg CO₂, 14% above the type median of 250.2 kg. It logged 4,125 hours at sea against a median of 2,106 hours for its type that year. 6.1% 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 (13,894 t) and the lowest 2019 (196 t). Its efficiency percentile within the type was 17 in both 2018 and 2025. Of the 5 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 227 of 1,348 qualifying chemical tankers by EEOI, at the 17th percentile. The dashed line is the type median, 14.4; this vessel reported 8.8.
EEOI divides emissions by transport work, which for this vessel and year was 1,573,484,711 tonne-miles over 48,670 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 110.2% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions rose 60.9% while distance sailed rose 92.5%and CO₂ per nautical mile fell 16.4%.That points mainly to how much the vessel sailed, rather than the other.
