ARKLOW WILLOW against its type

Built in 2019, it is 12 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 9,999 gross tonnage it is larger than 66% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 16 general cargo ships here under the Ireland flag, 0.5% of the 3,081 on the register. The same builder is recorded for 98 other vessels here, all of them general cargo ships. The returns for 2019–2025 all give Arklow as port of registry.

Its 4,803 t of CO₂ for 2025 is 1.7 times 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 164.8 kg CO₂, 35% above the type median of 122.2 kg. It logged 2,710 hours at sea against a median of 3,044 hours for its type that year. 4.6% 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 2021 (6,121 t) and the lowest 2019 (1,769 t). Its efficiency percentile within the type went from 19 in 2019 to 18 in 2025 (lower is more efficient). Of the 8 sister ships listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 89 of 479 qualifying general cargo ships by EEOI, at the 18th percentile. The dashed line is the type median, 29.4; this vessel reported 19.6.

EEOI divides emissions by transport work, which for this vessel and year was 244,572,811 tonne-miles over 29,138 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 171.5% higher than in 2019, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 10.1% while distance sailed fell 12.3%and CO₂ per nautical mile rose 2.5%.That points mainly to how much the vessel sailed, rather than the other.
