Earth Day Alliance, Inc.

In 1990, on April 22nd, the 20th anniversary of the first Earth Day, the movement went global and local. In San Luis Obispo County, grassroots activists joined with city and county agencies to coordinate its first Earth Day celebration. Originally known as the Earth Day Coalition (1990-1999) working under the ECOSLO umbrella, the group changed its name to the Earth Day Alliance, Inc. and became an independent nonprofit 501c3 in 2000.

The mission of the Earth Day Alliance (EDA) is to coordinate an annual free Earth Day event in order to raise awareness, address concerns, showcase solutions and present balanced modes of living for the wellbeing of each individual, the community, and the planet. It is a day to celebrate our natural resources and network the community with for profit and nonprofit organizations, schools, and government agencies who come to share their environmental message, cause, or product. This is a day to educate, motivate and activate everyone that attends.

EDA is a volunteer organization. It is through the talents, skills and volunteer hours of San Luis Obispo County residents, students and visitors that this free event is made possible. Beginning in January of each year the EDA Board and volunteers meet regularly to coordinate another Earth Day event for San Luis Obispo County. Everyone can be involved in some way.

Earth Day in San Luis Obispo County typically takes place on the weekend closest to the anniversary of Earth Day, April 22nd.

Funds to produce each Earth Day SLO Fair and Music Festival come from grants, sponsors, exhibitor fees and the Earth Day drawing. Items donated to the drawing and cash donations are tax deductible.

New EDA Board Members are inducted each year. If you are interested in becoming a board member please email: or call (805) 544-8529.
