HAPPY DIAMOND against its type

Built in 2011, it is 4 years newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 13,400 gross tonnage it is larger than 71% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 306 general cargo ships here under the Netherlands flag, 9.9% of the 3,081 on the register. The returns for 2018–2025 all give Amsterdam as port of registry.

Its 6,451 t of CO₂ for 2025 is 2.3 times the median of 2,820 t among the 2,469 general cargo ships on this register that reported for 2025. Per nautical mile it emitted 257.6 kg CO₂, 2.1 times the type median of 122.2 kg. It logged 2,033 hours at sea against a median of 3,044 hours for its type that year. 3.7% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 7 years with reported emissions, the highest was 2024 (12,645 t) and the lowest 2023 (1,516 t). Of the 8 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2018

Position 366 of 380 qualifying general cargo ships by EEOI, at the 96th percentile. The dashed line is the type median, 26.8; this vessel reported 117.7.

Reported CO₂ in 2025 was 2.4% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.

From 2024 to 2025, emissions fell 49.0% and CO₂ per nautical mile rose 3.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
