SunDay is a global day of action on September 21st, 2025, celebrating the unstoppable rise of clean energy. We’ll come together to showcase the power of the sun and wind -- energy sources that can power our world without pollution.

Our short walk (approx. 1 mile), led by joyous brass band music, will start at 1:00 pm at the Old South Church, and continue to the northeast corner of Boston Common (close to the steps that go up to State House, near the intersection of Park and Beacon Streets), followed by a brief multi-faith celebration of hope. All are welcome, especially families, whether guided by faith or personal conviction.

Speakers will include the dynamic Rev. Mariama White-Hammond!

Led by Boston Interfaith Climate Allies (BICA) with support from Third Act Massachusetts and GreenFaith.
