Sweden is set to implement a new road toll system in March with charges based on CO₂ emissions in addition to existing Euro emission classifications.

The changes follow the ratification of an updated Eurovignette agreement, now approved by all participating countries.

The revised system will apply to heavy goods vehicles over 12 tonnes, with fees determined by both Euro class and CO₂ efficiency. Vehicles will be divided into five CO₂ classes, with lower-emission trucks benefiting from reduced charges.

Euro 6 trucks will be placed in CO₂ Class 1 by default.

 A lower toll rate is available for vehicles with lower CO₂ emissions per tonne-kilometre. Emissions will be assessed using Vecto (Vehicle Energy Consumption Calculation Tool), an EU standard also used in Germany and Denmark.
