ASAHI PRINCESS against its type
Built in 2009, it is 1 year older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 55,909 gross tonnage it is smaller than 57% of the other 2,841 oil tankers with a recorded tonnage. It is one of 215 oil tankers here under the Greece flag, 6.1% of the 3,548 on the register. The same builder is recorded for 57 other vessels here, 42 of them oil tankers. The returns for 2022–2025 all give Piraeus as port of registry.
Its 2,811 t of CO₂ for 2025 is 65% 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 423.1 kg CO₂, close to the type median of 403.2 kg. It logged 662 hours at sea against a median of 2,030 hours for its type that year. 5.3% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 4 years with reported emissions, the highest was 2023 (16,555 t) and the lowest 2025 (2,811 t). Its efficiency percentile within the type went from 63 in 2022 to 77 in 2024 (lower is more efficient). Of the 2 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 42.4% lower than in 2022, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 74.2% and CO₂ per nautical mile fell 23.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
