Air quality conditions in the Tahoe Region can affect human health, visibility, forest health, and regional lake water quality, including the famed clarity of Lake Tahoe. The primary factors known to influence the Region’s air quality are motor vehicle emissions, vehicle entrainment of road dust, wildfire, residential wood smoke, topography, meteorology, and pollutants transported from sources outside the Region. Regional programs such as the regulation of wood stoves, reducing vehicle use through bike trails and transit, increased street sweeping, and improving forest health aim to improve air quality in the Region.
