Reported CO₂ by year
Reported CO₂ in 2024 was 81.7% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, 2022, so the series has gaps.
From 2023 to 2024, emissions fell 56.5% and CO₂ per nautical mile fell 13.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
