The reported port of registry changed: TURKU (2018–2023), then St. John's (2024–2025).
Its 3,701 t of CO₂ for 2025 is 31% 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 128.9 kg CO₂, close to the type median of 122.2 kg. It logged 2,653 hours at sea against a median of 3,044 hours for its type that year. 8.4% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 8 years with reported emissions, the highest was 2022 (7,783 t) and the lowest 2024 (2,304 t). Of the 8 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 43.5% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 60.7% and CO₂ per nautical mile fell 2.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
