New research from the U.S. Forest Service helps quantify the value of trees in communities across the nation. The research demonstrates how trees increase home prices, improve air quality, reduce household energy use and the effects of climate change. Nationally – the U.S. Forest Service suggests that the estimated 3.8-billion urban trees have a structural value of over two-trillion dollars and store carbon valued at over 14-billion dollars. The trees also remove air pollution valued at four-billion dollars each year – and remove carbon dioxide valued at around 460-million dollars per year.
