IMPRESSION BAY against its type
Built in 2015, it is 8 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 23,506 gross tonnage it is larger than 89% of the other 2,665 general cargo ships with a recorded tonnage. 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 reported port of registry changed: Hong Kong (2021), then Hong Kong, China (2022–2024).
Its 1,974 t of CO₂ for 2024 is 51% below the median of 4,046 t among the 1,395 general cargo ships on this register that reported for 2024. Per nautical mile it emitted 234.5 kg CO₂, 25% above the type median of 187.0 kg. It logged 779 hours at sea against a median of 2,074 hours for its type that year. 7.7% of its 2024 emissions were at berth; the median for general cargo ships was 3.9%. Across 3 years with reported emissions, the highest was 2022 (2,180 t) and the lowest 2021 (1,787 t). Of the 3 sister ships listed below with a 2024 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2021
Position 1,052 of 3,276 qualifying bulk carriers by EEOI, at the 32nd percentile. The dashed line is the type median, 8.4; this vessel reported 7.1.
EEOI divides emissions by transport work, which for this vessel and year was 251,044,944 tonne-miles over 8,462 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 10.4% higher than in 2021, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2022 to 2024, emissions fell 9.5% and CO₂ per nautical mile rose 11.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
