JOLLY DIAMANTE against its type
Built in 2011, it is 2 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). The same builder is recorded for 660 other vessels here, 2 of them vessels in the other ship types category. Its MRV returns name it JOLLY DIAMANTE for 2018–2021 and LIBERTY POWER for 2022–2025. The reported port of registry changed: Genoa (2018–2021), then Majuro (2022), then New York, NY (2023–2025).
Its 16,540 t of CO₂ for 2025 is 3.2 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 467.0 kg CO₂, 2.0 times the type median of 231.1 kg. It logged 2,503 hours at sea against a median of 2,231 hours for its type that year. 1.2% of its 2025 emissions were at berth; the median for vessels in the other ship types category was 3.9%. Across 8 years with reported emissions, the highest was 2025 (16,540 t) and the lowest 2024 (756 t). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2025
Position 103 of 119 qualifying other ship typess by EEOI, at the 86th percentile. The dashed line is the type median, 69.3; this vessel reported 188.1.
EEOI divides emissions by transport work, which for this vessel and year was 87,947,200 tonne-miles over 35,420 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 47.8% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 2,087.5% and CO₂ per nautical mile rose 38.3%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
