GULLHOLMEN ISLAND 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). It is one of 73 general cargo ships here under the Hong Kong flag, 2.4% of the 3,081 on the register. The same builder is recorded for 80 other vessels here, 22 of them general cargo ships. The returns for 2021–2025 all give Hong Kong, China as port of registry.
Its 3,330 t of CO₂ for 2025 is 18% above 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 267.7 kg CO₂, 2.2 times the type median of 122.2 kg. It logged 996 hours at sea against a median of 3,044 hours for its type that year. 2.3% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 5 years with reported emissions, the highest was 2021 (4,729 t) and the lowest 2023 (1,724 t). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2021
Position 2,865 of 3,276 qualifying bulk carriers by EEOI, at the 87th percentile. The dashed line is the type median, 8.4; this vessel reported 13.0.
EEOI divides emissions by transport work, which for this vessel and year was 362,656,442 tonne-miles over 18,604 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 29.6% lower than in 2021, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 64.8% and CO₂ per nautical mile rose 27.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
