CHELSEA-1 against its type
Built in 2008, it is 1 year newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 5,226 gross tonnage it is smaller than 60% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 67 general cargo ships here under the Palau flag, 2.2% of the 3,081 on the register. The returns for 2018–2025 all give Malakal Harbor as port of registry.
Its 689 t of CO₂ for 2025 is 76% 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 65.6 kg CO₂, 46% below the type median of 122.2 kg. It logged 1,748 hours at sea against a median of 3,044 hours for its type that year. 3.1% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 7 years with reported emissions, the highest was 2025 (689 t) and the lowest 2021 (95 t). Of the 6 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 85 of 479 qualifying general cargo ships by EEOI, at the 18th percentile. The dashed line is the type median, 29.4; this vessel reported 19.4.
EEOI divides emissions by transport work, which for this vessel and year was 35,568,921 tonne-miles over 10,499 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 224.9% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2024 to 2025, emissions rose 1.7% and CO₂ per nautical mile fell 14.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
