Established nearly 43 years ago, Earth Month began because of the urgings of Wisconsin Senator Gaylord Nelson, who believed that grassroots environmental activism was capable of causing lasting change. Now, Earth Month is celebrated all over the world, with associated festivities and activism usually concluding on April 22.

At George Mason University, Earth Month activities are promoted with sustainability events throughout the entirety of April, but with special events hosted the fourth week of the month. Many of the Earth Week events are hosted by Mason’s Office of Sustainability (OoS).
