Sharon Green Day is SSC’s signature, annual event. Green Day takes place on the first Saturday of each May for four hours at the Sharon High School. The entire community is invited to participate in a day of discussion, exhibition, demonstration, education, games, arts and fun with a focus on the most pressing environmental issues. It also serves as SSC’s major fundraiser for operating costs and monthly programming. A seven year tradition (paused during COVID-19), the event welcomes hundreds of people and dozens of environmental vendors. It is free, family-friendly, and a great way to learn about what’s happening with sustainability, locally and beyond. The event attracts over 600 people of all ages and backgrounds who are interested in learning practical tips about sustainability.
