SONGA SAPPHIRE 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 11,259 gross tonnage it is smaller than 96% 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 returns for 2018–2025 all give Valletta as port of registry.
Its 10,194 t of CO₂ for 2025 is 29% 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 330.9 kg CO₂, 18% below the type median of 403.2 kg. It logged 3,697 hours at sea against a median of 2,030 hours for its type that year. 13.9% 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 (22,769 t) and the lowest 2018 (8,306 t). Its efficiency percentile within the type went from 90 in 2018 to 99 in 2025 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,440 of 1,448 qualifying oil tankers by EEOI, at the 99th percentile. The dashed line is the type median, 7.5; this vessel reported 40.4.
EEOI divides emissions by transport work, which for this vessel and year was 252,086,795 tonne-miles over 30,806 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 22.7% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 6.4% while distance sailed fell 4.6%and CO₂ per nautical mile fell 1.9%.That points mainly to how much the vessel sailed, rather than the other.
