HAPPY ROVER against its type
Built in 1997, it is 10 years older than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 10,990 gross tonnage it is larger than 67% 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 same builder is recorded for 20 other vessels here, 3 of them general cargo ships. The returns for 2021–2025 all give Amsterdam as port of registry.
Its 8,058 t of CO₂ for 2025 is 2.9 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 282.7 kg CO₂, 2.3 times the type median of 122.2 kg. It logged 2,502 hours at sea against a median of 3,044 hours for its type that year. 3.4% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 8 years with reported emissions, the highest was 2018 (8,879 t) and the lowest 2021 (1,725 t). Its efficiency percentile within the type went from 91 in 2018 to 90 in 2020 (lower is more efficient). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2020
Position 242 of 270 qualifying general cargo ships by EEOI, at the 90th percentile. The dashed line is the type median, 23.3; this vessel reported 42.7.
EEOI divides emissions by transport work, which for this vessel and year was 63,593,633 tonne-miles over 16,775 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 9.3% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 1.1% and CO₂ per nautical mile rose 18.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
