Norway has a national Road Tolling Scheme with a low emission aspect, which operates major and national roads, and in a number of cities. 

Some Norwegian cities have a Low Emission Zone, where the cost of the road toll is higher for more polluting vehicles. These cities have a green LEZ scheme below, but the information can be found under the toll scheme for the city in question.

A number of Norwegian cities have also introduced Emergency Schemes for times of high air pollution.

One city has a Zero Emission Zone in place: Oslo.
Bergen, Oslo and Trondheim have also a Studded Tyre Charge.
