BRO ANNA against its type

Built in 2008, it is 2 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 12,164 gross tonnage it is smaller than 94% of the other 2,841 oil tankers with a recorded tonnage. It is one of 237 oil tankers here under the Singapore flag, 6.7% of the 3,548 on the register. The returns for 2018–2025 all give Singapore as port of registry.

Its 9,279 t of CO₂ for 2025 is 17% above the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 292.3 kg CO₂, 28% below the type median of 403.2 kg. It logged 3,471 hours at sea against a median of 2,030 hours for its type that year. 10.5% 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 (10,218 t) and the lowest 2018 (3,698 t). Its efficiency percentile within the type went from 92 in 2019 to 100 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,441 of 1,448 qualifying oil tankers by EEOI, at the 100th percentile. The dashed line is the type median, 7.5; this vessel reported 40.6.

EEOI divides emissions by transport work, which for this vessel and year was 228,501,108 tonne-miles over 31,746 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 150.9% higher than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 17.0% while distance sailed rose 26.1%and CO₂ per nautical mile fell 7.3%.That points mainly to how much the vessel sailed, rather than the other.
