NISSOS KYTHNOS against its type
It is one of 793 oil tankers here under the Marshall Islands flag, 22.4% of the 3,548 on the register. The returns for 2022–2025 all give Majuro as port of registry.
Its 3,891 t of CO₂ for 2025 is 51% 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 590.9 kg CO₂, 47% above the type median of 403.2 kg. It logged 641 hours at sea against a median of 2,030 hours for its type that year. 18.7% 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 (42,630 t) and the lowest 2024 (1,206 t). Its efficiency percentile within the type went from 14 in 2022 to 15 in 2023 (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.
