I was driving to work today and was taken by the incredible fall colors. Snapped this picture of the cotton woods and maples in city park. New research by government-backed scientists at the National Center for Atmospheric Research finds that deciduous vegetation absorbs one-third more air pollution than previously believed. Just make sure you plant the right type of tree since the benefits are very species dependent, with some trees like eucalyptus and poplar emitting more volatile organic compounds than they absorb. See Friday’s Denver Post article for more details.
In Chula Vista we used Citygreen to estimate reductions in greenhouse gas emissions linked to strategies to increase vegetative cover within developments. The program also calculates the amount of pollutants removed from the air and reduced expenses associated with a reduction in storm water runoff. The findings were already impressive. Sounds like numbers should have been even higher.
