Reported CO₂ by year
Reported CO₂ in 2025 was 61.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2024, so the series has gaps.
From 2023 to 2025, emissions fell 63.6% and CO₂ per nautical mile fell 10.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
