Environmental zones (Miljözon) in Sweden

All cities in Sweden are required to guarantee their residents acceptable air quality. Therefore, in many cities, NOx and PM emissions need to be reduced and this is to be achieved through the implementation of environmental zones.

In Swedish environmental zones (Miljözon Stockholm, Gothenburg, Malmö, Uppsala, Helsingborg, Lund and Umeå) Proventia has retrofitted hundreds of city buses and trucks with NOxBUSTER® DPF + SCR system upgrading vehicles' emission classes up to EURO 5/ 6. Retrofitted vehicles (Euro 5) are allowed to drive into environmental zones up to 2020. Euro 6 vehicles do not have any time limitations at the moment.

Proventia NOxBUSTER® DPF+SCR system has been type-approved for upgrading heavy vehicles, buses and trucks, from EURO 2 and 3 to EURO 5 in Swedish Environmental Zones (Miljözon). Type approval means that a vehicle equipped with NOxBUSTER® system can at the inspection receive a marking of emission class upgrade to the registration certificate.
