Project Learning Tree uses trees and forests as windows on the world to increase students’ understanding of the environment and actions they can take to conserve it. Since 1976, PLT has reached 138 million students and trained 765,000 educators to help students learn how to think, not what to think about complex environmental issues.

Project Learning Tree helps develop students’ awareness, knowledge, and appreciation of the environment, builds their skills and ability to make informed decisions, and encourages them to take personal responsibility for sustaining the environment and our quality of life that depends on it. From its beginnings in 1976, PLT has exemplified high-quality environmental education.
