WECO JOSEFINE: CO₂ emissions 2018–2025

WECO JOSEFINE against its type

Built in 2018, it is 11 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 23,703 gross tonnage it is larger than 89% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 51 general cargo ships here under the Singapore flag, 1.7% of the 3,081 on the register. The returns for 2018–2024 all give SINGAPORE as port of registry.

Its 2,699 t of CO₂ for 2025 is close to 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 206.7 kg CO₂, 1.7 times the type median of 122.2 kg. It logged 1,200 hours at sea against a median of 3,044 hours for its type that year. 7.1% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 6 years with reported emissions, the highest was 2024 (5,081 t) and the lowest 2022 (1,256 t). Its efficiency percentile within the type went from 38 in 2018 to 0 in 2025 (lower is more efficient). Of the 4 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 3 of 479 qualifying general cargo ships by EEOI, at the 0th percentile. The dashed line is the type median, 29.4; this vessel reported 7.6.

EEOI divides emissions by transport work, which for this vessel and year was 356,575,958 tonne-miles over 13,057 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 17.2% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, so the series has gaps.

From 2024 to 2025, emissions fell 46.9% while distance sailed fell 41.1%and CO₂ per nautical mile fell 9.8%.That points mainly to how much the vessel sailed, rather than the other.
