Earth Day: A Global Movement for Change

04/21/26

Earth Day, celebrated each year on April 22, is a global event dedicated to raising awareness and inspiring action to protect our environment. The first Earth Day in 1970 emerged in response to ecological disasters, such as the 1969 Santa Barbara Oil Spill, with its focus on increasing public awareness to issues such as air and water pollution. By 1990, Earth Day had grown into a full month of community activities and initiatives dedicated to reducing environmental impact and promoting sustainable practices. Today, the celebration is observed in more than 193 countries and remains one of the most influential civic events in the world.

During Earth Month, communities around the world come together throughout April to celebrate our planet and recommit to protect it, highlighting the importance of sustainable practices and conservation. This year's theme focuses on "Our Power, Our Planet," which reflects a simple but important truth: environmental progress is not solely driven by one policy or leader. It is built through the everyday actions of individuals, families, schools, and communities who care about where they live.

The County of San Diego (County) has an ongoing commitment to sustainability, reflected in our Strategic Initiatives and our Climate Action Plan (CAP), which charts a course toward net-zero greenhouse gas emissions by 2045, for both unincorporated communities and County facilities.

See how you can join the County in celebrating the Earth everyday by signing up for our monthly newsletter, and following us on Facebook, Instagram, and X. You can also join us at any of the upcoming events for Earth Month. Whether it's a small change at home or a bigger commitment to your community, every action counts!
