There is currently only one low emission zone in Finland - in the city of Helsinki. The Low Emission Zone covers the entire city centre south of Hakamäentie Street. But there are special rules here.
Helsinki is certainly one of the cleanest cities in Europe. This is partly due to its geographical location, as a large part of the city is enclosed by the sea on three sides. This always ensures a stiff breeze, so that air pollution can spread quickly here. A specific problem in the Finnish capital is the high level of fine particles in the air in spring. As the city spreads large amounts of sand on the roads in winter to prevent icy roads, a special road dust is created when it gets warmer again and ice and snow melt. This dust carries large amounts of fine particles.
This is another reason why a zone has been introduced where there are access restrictions. But basically, the Finnish Low Emission Zone is not a classic zone for everyone as it is in other European countries, because it only applies to very few vehicles. As a resident or tourist, you hardly notice it, even if you drive in with your own car. Only the city buses and the refuse collection service are affected by the restrictions. When purchasing new vehicles, the municipal companies have to make sure that their refuse collection vehicles at least comply with Euroclass 5; for the city buses, Euroclass 3 was sufficient at first, but now Euroclass 5 is also necessary to be allowed to drive into the city centre. But even if the buses and refuse collection vehicles do not meet these Euro standards, upgrading to a higher Euro class is possible and is recognised.
You can only travel around in such a relaxed way in a few European cities. Green-Zones wishes you a safe journey!
