SOLAR KATHERINE against its type
Built in 2020, it is 10 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 29,591 gross tonnage it is smaller than 77% of the other 2,841 oil tankers with a recorded tonnage. It is one of 244 oil tankers here under the Panama flag, 6.9% of the 3,548 on the register. The same builder is recorded for 983 other vessels here, 270 of them oil tankers. The returns for 2021–2025 all give PANAMA as port of registry.
Its 7,011 t of CO₂ for 2025 is 11% 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 277.1 kg CO₂, 31% below the type median of 403.2 kg. It logged 2,130 hours at sea against a median of 2,030 hours for its type that year. 12.8% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 5 years with reported emissions, the highest was 2021 (9,275 t) and the lowest 2022 (3,552 t). Its efficiency percentile within the type went from 70 in 2021 to 67 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 967 of 1,448 qualifying oil tankers by EEOI, at the 67th percentile. The dashed line is the type median, 7.5; this vessel reported 9.1.
EEOI divides emissions by transport work, which for this vessel and year was 768,726,974 tonne-miles over 25,304 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 24.4% lower than in 2021, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 68.4% while distance sailed rose 65.5%and CO₂ per nautical mile rose 1.7%.That points mainly to how much the vessel sailed, rather than the other.
