Joensuu's air quality is excellent by European standards, benefiting from the Finnish North Karelia boreal forest and Baltic airflows providing clean background conditions in this eastern Finnish lakeside city. Vehicle traffic on the E63 and wood-burning stoves during the long cold winters are the primary local sources, while the surrounding Lake Pyhäselkä and the extensive Karelian forest and lake landscape maintain Joensuu among Finland's cleaner urban environments throughout most of the year.
