BNC's Net Zero Event Ribbon Cutting

Boston Nature Center & Wildlife Sanctuary

Five months ago, Mass Audubon’s Boston Nature Center (BNC) in Mattapan broke ground on an ambitious project to become carbon neutral by 2022. So, it is especially fitting that on Earth Day Friday, April 22, members of the BNC community, supporters, civic leaders, and Mass Audubon staff gathered at the 67-acre wildlife sanctuary for a ribbon-cutting to officially announce it has achieved net-zero energy status.
