CHELSEA-7 against its type
Built in 2010, it is 3 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 5,231 gross tonnage it is smaller than 60% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 69 general cargo ships here under the Malta flag, 2.2% of the 3,081 on the register. The returns for 2018–2025 all give Valletta as port of registry.
Its 828 t of CO₂ for 2025 is 71% below 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 71.2 kg CO₂, 42% below the type median of 122.2 kg. It logged 1,683 hours at sea against a median of 3,044 hours for its type that year. 3.9% 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 2024 (1,305 t) and the lowest 2019 (142 t). Of the 7 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 125 of 479 qualifying general cargo ships by EEOI, at the 26th percentile. The dashed line is the type median, 29.4; this vessel reported 22.8.
EEOI divides emissions by transport work, which for this vessel and year was 36,379,341 tonne-miles over 11,629 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 221.9% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 36.6% and CO₂ per nautical mile fell 2.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
