GPO SAPPHIRE against its type
Built in 2019, it is 10 years newer than the median vessel in the other ship types category on this register, which was built in 2009 (451 vessels with a known build year). At 45,100 gross tonnage it is larger than 97% of the other 436 vessels in the other ship types category with a recorded tonnage. It is one of 25 vessels in the other ship types category here under the Marshall Islands flag, 5.0% of the 499 on the register. The returns for 2021–2025 all give Majuro as port of registry.
Its 21,345 t of CO₂ for 2025 is 4.2 times the median of 5,122 t among the 335 vessels in the other ship types category on this register that reported for 2025. Per nautical mile it emitted 632.0 kg CO₂, 2.7 times the type median of 231.1 kg. It logged 3,327 hours at sea against a median of 2,231 hours for its type that year. 5.8% of its 2025 emissions were at berth; the median for vessels in the other ship types category was 3.9%. Across 4 years with reported emissions, the highest was 2024 (29,499 t) and the lowest 2021 (10,316 t). Of the 4 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 44 of 119 qualifying other ship typess by EEOI, at the 36th percentile. The dashed line is the type median, 69.3; this vessel reported 54.2.
EEOI divides emissions by transport work, which for this vessel and year was 393,754,473 tonne-miles over 33,772 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 106.9% higher than in 2021, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.
From 2024 to 2025, emissions fell 27.6% and CO₂ per nautical mile fell 5.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
