AQUARIUS against its type
Built in 2005, it is 3 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 6,454 gross tonnage it is smaller than 99% of the other 3,000 container ships with a recorded tonnage. It is one of 3 container ships here under the Latvia flag, 0.1% of the 3,495 on the register. The same builder is recorded for 35 other vessels here, 26 of them container ships. Its MRV returns name it X-PRESS VESUVIO for 2019–2022 and AQUARIUS for 2025. The reported port of registry changed: Valetta (2020–2022), then Riga (2025).
Its 6,529 t of CO₂ for 2025 is 60% 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 195.0 kg CO₂, 64% below the type median of 545.6 kg. It logged 2,812 hours at sea against a median of 3,155 hours for its type that year. 5.8% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 5 years with reported emissions, the highest was 2019 (10,373 t) and the lowest 2025 (6,529 t). Its efficiency percentile within the type went from 95 in 2021 to 94 in 2022 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 37.1% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2023, 2024, so the series has gaps.
From 2022 to 2025, emissions fell 33.8% and CO₂ per nautical mile fell 9.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
