ARROW STAR 1 against its type
Built in 2007, it is 3 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 7,833 gross tonnage it is smaller than 97% of the other 2,841 oil tankers with a recorded tonnage. It is one of 289 oil tankers here under the Malta flag, 8.1% of the 3,548 on the register. The same builder is recorded for 39 other vessels here, 11 of them oil tankers. The returns for 2019–2025 all give Valletta as port of registry.
Its 2,597 t of CO₂ for 2025 is 67% below the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 217.7 kg CO₂, 46% below the type median of 403.2 kg. It logged 2,276 hours at sea against a median of 2,030 hours for its type that year. 10.4% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 6 years with reported emissions, the highest was 2019 (7,105 t) and the lowest 2025 (2,597 t). Its efficiency percentile within the type was 98 in both 2019 and 2024. Of the 6 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 63.4% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions fell 59.8% and CO₂ per nautical mile rose 14.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
