HUANGHAI DEVELOPER against its type
Built in 2013, it is 6 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 20,682 gross tonnage it is larger than 80% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 216 general cargo ships here under the Liberia flag, 7.0% of the 3,081 on the register. Its MRV returns name it HUANGHAI DEVELOPER for 2019–2021 and USG ZURICH for 2023–2025. The reported port of registry changed: Hong Kong (2019–2021), then MONROVIA (2023–2025).
Its 3,497 t of CO₂ for 2025 is 24% 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 203.5 kg CO₂, 1.7 times the type median of 122.2 kg. It logged 1,684 hours at sea against a median of 3,044 hours for its type that year. 12.3% 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 2019 (4,761 t) and the lowest 2024 (697 t). Its efficiency percentile within the type went from 38 in 2019 to 32 in 2024 (lower is more efficient). Of the 3 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 105 of 321 qualifying general cargo ships by EEOI, at the 32nd percentile. The dashed line is the type median, 23.6; this vessel reported 18.9.
EEOI divides emissions by transport work, which for this vessel and year was 36,900,000 tonne-miles over 3,532 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 26.6% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2020, 2022, so the series has gaps.
From 2024 to 2025, emissions rose 401.4% and CO₂ per nautical mile rose 3.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
