ALCEDO against its type
Built in 2003, it is 7 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 6,556 gross tonnage it is smaller than 98% of the other 2,841 oil tankers with a recorded tonnage. It is one of 5 oil tankers here under the Netherlands flag, 0.1% of the 3,548 on the register. Its MRV returns name it ALCEDO for 2018–2019 and BIT POWER for 2020–2025. The reported port of registry changed: Limassol (2018–2019), then Dordrecht (2020–2025).
Its 8,428 t of CO₂ for 2025 is close to the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 160.1 kg CO₂, 60% below the type median of 403.2 kg. It logged 4,880 hours at sea against a median of 2,030 hours for its type that year. 10.9% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2019 (9,634 t) and the lowest 2021 (7,066 t). Its efficiency percentile within the type went from 100 in 2020 to 98 in 2021 (lower is more efficient). Of the 5 comparable vessels 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 2.2% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 11.4% and CO₂ per nautical mile rose 4.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
