MARY ARCTICA against its type
Built in 2007, it is the same age as the median general cargo ship on this register (build year 2007, 2,852 vessels with a known build year). At 10,308 gross tonnage it is larger than 66% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 112 general cargo ships here under the Norway flag, 3.6% of the 3,081 on the register. The same builder is recorded for 13 other vessels here, one of them a general cargo ship. Its MRV returns name it MARY ARCTICA for 2019–2021 and SILVER MARY for 2024–2025. The reported port of registry changed: Aalborg (2019–2021), then BERGEN (2024–2025).
Its 4,227 t of CO₂ for 2025 is 50% above 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 202.9 kg CO₂, 1.7 times the type median of 122.2 kg. It logged 1,718 hours at sea against a median of 3,044 hours for its type that year. 13.5% 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 2019 (12,599 t) and the lowest 2024 (3,448 t). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Reported CO₂ by year
Reported CO₂ in 2025 was 66.4% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions rose 22.6% and CO₂ per nautical mile fell 12.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
