The ECOS-hosted Sacramento Earth Day is the largest Earth Day celebration in the Sacramento region. It’s free, and it provides thousands of attendees with information on sustainability. The 2023 theme was GROW NATIVE.

This theme was about expanding the use of native plants in our region, in city streetscapes and home landscapes – how they withstand drought and heat conditions; use little water; provide a beneficial habitat to insects, pollinators, birds, and animals; create sustainable, cool, and shady streetscapes, as well as beautiful home landscapes.
