Tree Facts

Trees Can Do Just About Everything.

Here are a few “tree facts”:

  • Trees give us oxygen, clean the air, and filter airborne pollutants.
  • Trees conserve energy.  Just three strategically placed trees can decrease utility bills by 50%.
  • Urban trees in the U.S. remove 711,000 tons of air pol­lu­tion annu­ally, at a value of $3.8 billion.
  • Trees and vegetation can raise property values up to 37%.
  • Trees can reduce annual storm water runoff by 2% — 7%.
  • The net cooling effect of a healthy tree is equiv­a­lent to 10 room-size air con­di­tion­ers oper­at­ing 20 hours a day.
  • Trees clean the air by absorbing carbon dioxide, sulfur dioxide, nitrous oxides and other pollutants.
  • Trees shade cars and parking lots, reducing ozone emissions from vehicles.
  • Trees filter airborne pollutants and reduce the conditions that cause asthma and other respiratory problems.
  • Get trees. Get healthy.  Children and youth living in greener neighborhoods have lower body mass index.
  • Trees reduce noise pollution by absorbing sounds.
  • Urban trees in the U.S. store 700 million tons of carbon valued at $14 billion with an annual carbon sequestration rate of 22.8 million tons per year valued at $460 million annually.
  • Trees provide habitat for hundreds of species.
