Sweden has a national framework with Low Emission Zones in 8 cities. These LEZs only apply to lorries and buses. The only exception to this national framework is Stockholm, whose LEZ has also been affecting cars since 1 January 2020.
The low emission zone framework means that only the location varies from city to city.
The Charging Schemes (Congestion Road Tolls) are implemented through a national scheme and are very similar, but not identical.
From 2024 there will also be a zero emission zone in Stockholm in place. The Swedish national framework categorizes it under low emission zone class 3.
Sweden also has various Access Regulations such as studded tyre bans, lorry regulations and a car & coach free zone.
