Espoo's air quality is excellent by European standards, sharing Helsinki's clean Baltic Sea and Gulf of Finland airflows that dominate conditions throughout most of the year. The primary concerns are road dust from studded winter tyres contributing elevated PM10 in spring and wood-burning stoves adding localised winter PM2.5 in residential areas, while the Nuuksio National Park to the northwest provides a substantial clean-air green lung for Finland's second-largest city.
