Reported CO₂ by year

2024: 12,715 t202412,7152025: 42,489 t202542,489

Reported CO₂ in 2025 was 234.2% higher than in 2024, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 234.2% while distance sailed rose 199.3%and CO₂ per nautical mile rose 11.6%.That points mainly to how much the vessel sailed, rather than the other.
