CHEMROAD SIRIUS against its type
Built in 2018, it is 8 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 21,254 gross tonnage it is smaller than 54% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 259 chemical tankers here under the Panama flag, 11.0% of the 2,344 on the register. The same builder is recorded for 307 other vessels here, 98 of them chemical tankers. The returns for 2018–2024 all give PANAMA as port of registry.
Its 1,323 t of CO₂ for 2025 is 76% below the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 213.2 kg CO₂, 15% below the type median of 250.2 kg. It logged 543 hours at sea against a median of 2,106 hours for its type that year. 1.8% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2022 (6,762 t) and the lowest 2025 (1,323 t). Its efficiency percentile within the type went from 14 in 2018 to 9 in 2023 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 34.8% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, so the series has gaps.
From 2024 to 2025, emissions fell 2.2% and CO₂ per nautical mile rose 5.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
