Reported CO₂ by year
Reported CO₂ in 2025 was 44.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, so the series has gaps.
From 2024 to 2025, emissions rose 163.0% and CO₂ per nautical mile fell 10.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
