Celebrate sustainability in action at the Earth Day 2026 Festival, a free gathering from noon to 6pm in Union Square. Expect a full afternoon of climate-focused, family-friendly programming, including interactive workshops, live performances, "climate art" and activities. Dozens of environmental nonprofits and green businesses will be on hand, alongside sustainable food vendors, to make it easy (and fun) to learn how to live a little greener.
