Trees Play a Key Role in a Sustainable Urban Future

Urban trees remove over 710,000 tons of air pollution per year in the U.S., which has a major impact on fighting respiratory illnesses like asthma. Trees also filter up to 80% of phosphorus out of stormwater before it pollutes waterways and drinking water. And tree canopy shade, along with evapotranspiration (the return of water vapor from trees and vegetation back to the atmosphere), can lower peak temperatures by 2°-9°F—a key tool in combating the heat island effect present in many cities, which disproportionately impacts lower-income neighborhoods and other vulnerable populations.
