Reported CO₂ by year
Reported CO₂ in 2024 was 71.6% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, 2022, 2023, so the series has gaps.
From 2018 to 2024, emissions fell 71.6% and CO₂ per nautical mile fell 55.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
