ATLAS STAR against its type
Built in 2008, it is 2 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 24,066 gross tonnage it is larger than 56% 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 192 other vessels here, 87 of them chemical tankers. Its MRV returns name it NORD SNOW QUEEN for 2018–2021 and ATLAS STAR for 2022–2025. The reported port of registry changed: Singapore (2018–2021), then Valleta (2022), then Monrovia (2025).
Its 2,247 t of CO₂ for 2025 is 59% below the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 351.2 kg CO₂, 40% above the type median of 250.2 kg. It logged 565 hours at sea against a median of 2,109 hours for its type that year. 8.5% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2021 (12,949 t) and the lowest 2025 (2,247 t). Its efficiency percentile within the type went from 72 in 2018 to 55 in 2024 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 79.7% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2024 to 2025, emissions fell 34.6% and CO₂ per nautical mile rose 5.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
