The study, requested by the City of Portland, shows the substantial cooling effect of planting trees and vegetation in urban areas. The study informed decision makers in Portland how adding vegetation, using reflective material on hard surfaces, and installing green roofs on buildings can cool urban heat islands, as much as 25 degrees in some spots.
