Earth Month®

51 years ago on April 22, 1970 the first Earth Day took place with the participation of 20 million Americans. This was the catalyst for environmental action across the United States and eventually worldwide. At ASU we know that a single day isn’t enough.

Join us in celebrating our collective successes and innovative solutions for a sustainable future. At Arizona State University, every day is Earth Day.
