BALTIC SUN II against its type
Built in 2005, it is 5 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 23,235 gross tonnage it is larger than 50% 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 983 other vessels here, 330 of them chemical tankers. Its MRV returns name it BALTIC SUN II for 2018–2022 and MILANO for 2023–2025. The reported port of registry changed: Valletta (2019–2022), then MONROVIA (2023–2025).
Its 978 t of CO₂ for 2025 is 82% 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 669.3 kg CO₂, 2.7 times the type median of 250.2 kg. It logged 253 hours at sea against a median of 2,109 hours for its type that year. 3.9% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2018 (14,698 t) and the lowest 2025 (978 t). Its efficiency percentile within the type went from 73 in 2018 to 96 in 2024 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 93.3% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 75.3% and CO₂ per nautical mile rose 144.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
