Urban Vegetation Air Quality Information Program
This page last reviewed May 15, 2003
|Urban vegetation plays an important part in the quality of
life. The obvious roles are pleasant aesthetics, shading, photosynthesis, absorbing gaseous pollutants, wind speed
reduction, and property value appreciation, while the less obvious ones include evapotranspiration, intercepting
and storing rainfall, absorbing high frequency noise, and many more. However, not all vegetation processes the
same level of benefits. Some vegetation emits gases and particles that can adversely impact air quality. Vegetation
chosen carefully and correctly for urban planting can measurably reduce air quality impacts.
The objective of a Urban Vegetation Air Quality Information Program is to provide consumers with additional information that air quality is another factor that should be considered when purchasing vegetation. Urban vegetation is defined as plants or trees in parks, yards, public spaces, along streets, in commercial and residential areas.
