The implementation of CO₂ tolls is not uniformly applied across the EU.
 
The main reason is that the 2022 Eurovignette Directive uses a digital, distance-based measure to calculate tolls.
 
However, not all EU countries are using this approach, some countries such as France have gated, distance-based tolls, other such as the Netherlands have time-based tolls or vignettes.
