GPO AMETHYST against its type
Built in 2018, it is 9 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 49,091 gross tonnage it is larger than 98% 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 same builder is recorded for 80 other vessels here, 4 of them vessels in the other ship types category. The returns for 2019–2025 all give Majuro as port of registry.
Its 20,165 t of CO₂ for 2025 is 3.9 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 748.7 kg CO₂, 3.2 times the type median of 231.1 kg. It logged 2,920 hours at sea against a median of 2,231 hours for its type that year. 1.6% of its 2025 emissions were at berth; the median for vessels in the other ship types category was 3.9%. Across 5 years with reported emissions, the highest was 2019 (21,036 t) and the lowest 2020 (3,232 t). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2025
Position 105 of 119 qualifying other ship typess by EEOI, at the 88th percentile. The dashed line is the type median, 69.3; this vessel reported 202.8.
EEOI divides emissions by transport work, which for this vessel and year was 99,443,634 tonne-miles over 26,932 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 4.1% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2022, 2024, so the series has gaps.
From 2023 to 2025, emissions rose 241.0% and CO₂ per nautical mile rose 6.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
