EARTHDAY.ORG’s founders created and organized the very first Earth Day on April 22, 1970. Since then, Earth Day Network also known as EARTHDAY.ORG has been mobilizing over 1 billion people annually on Earth Day, and every other day, to protect the planet
In 2025, we celebrate the 55th anniversary of Earth Day. To mark this milestone, we invite everyone to support Earth Day’s 2025 theme: OUR POWER, OUR PLANET™. Let’s unite in our collective global commitment to renewable energy, whether it’s solar, wind, hydroelectric, geothermal or tidal – to generate clean electricity for everyone.
