GreenFerries is a hobby project, all the data shown here has no official value. It is Open Source, so you can double check and modify it.
The Ecoscore compares
average CO₂ emissions per passenger per km.
‟emits like 2.1 planes” means that the ferry emits more than twice what an average plane would on the same distance for one passenger.
