Tartu's air quality is generally good by European standards, benefiting from the flat Estonian lowland and consistent Baltic and North Atlantic airflows providing reliable ventilation. Vehicle traffic on the E264 and wood-burning stoves during the long cold winters are the primary local sources, while the surrounding boreal forest and Estonian lake district maintain moderate air quality levels throughout most of the year.
