ARTAX against its type
Built in 2014, it is 7 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 22,861 gross tonnage it is larger than 85% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 187 general cargo ships here under the Portugal flag, 6.1% of the 3,081 on the register. The same builder is recorded for 103 other vessels here, 3 of them general cargo ships. Its MRV returns name it GLOBAL EFFORT for 2020–2022 and ARTAX for 2024–2025. The reported port of registry changed: PANAMA (2020–2022), then Nassau (2024), then Madeira (2025).
Its 648 t of CO₂ for 2025 is 77% 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 300.5 kg CO₂, 2.5 times the type median of 122.2 kg. It logged 343 hours at sea against a median of 3,044 hours for its type that year. 9.7% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 5 years with reported emissions, the highest was 2021 (4,814 t) and the lowest 2025 (648 t). Its efficiency percentile within the type went from 81 in 2020 to 68 in 2024 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 52.9% lower than in 2020, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions fell 77.8% and CO₂ per nautical mile rose 46.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
