ARA ATLANTIS against its type

Built in 2007, it is 1 year older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 9,962 gross tonnage it is smaller than 91% of the other 3,000 container ships with a recorded tonnage. It is one of 307 container ships here under the Portugal flag, 8.8% of the 3,495 on the register. The same builder is recorded for 180 other vessels here, 110 of them container ships. Its MRV returns name it ARA ATLANTIS for 2018–2020, ATLANTIS A for 2021–2024 and X-PRESS TAGUS for 2025. The reported port of registry changed: Gibraltar (2018–2019), then Madeira (2020–2025).

Its 10,108 t of CO₂ for 2025 is 38% below the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 242.8 kg CO₂, 56% below the type median of 545.6 kg. It logged 3,634 hours at sea against a median of 3,155 hours for its type that year. 4.2% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2018 (14,988 t) and the lowest 2025 (10,108 t). Its efficiency percentile within the type went from 85 in 2018 to 90 in 2025 (lower is more efficient). Of the 8 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,647 of 1,838 qualifying container ships by EEOI, at the 90th percentile. The dashed line is the type median, 14.2; this vessel reported 36.8.

EEOI divides emissions by transport work, which for this vessel and year was 274,377,579 tonne-miles over 41,631 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 32.6% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 10.9% while distance sailed fell 3.9%and CO₂ per nautical mile fell 7.3%.That points mainly to how efficiently it sailed, rather than the other.

Where the 2025 emissions occurred

Methane, nitrous oxide and EU ETS2025

Total CO₂ equivalent: 10,267 t
Methane (CH₄): 0.16 t
Nitrous oxide (N₂O): 0.58 t
