350 Mass

Mission: 350 Mass is a statewide, grassroots, member-led, campaign-focused network committed to a just transition for a climate-safe world.

Statewide because we focus on how the Commonwealth can meet its climate goals through legislation, regulation, and local action.

Grassroots because we build our strength from Massachusetts residents who care deeply about the climate and climate justice.

Member-led because as members we determine the direction of our work in partnership with our staff.

Campaign-focused because we set specific goals and measure accomplishments along the way to a sustainable climate for all of us.

Climate justice because climate change affects communities differently, and we believe it is important to center those most impacted in our efforts for a just and climate-safe future.

350 Mass is a dynamic organization managed by a member-led Statewide Steering Team, made up of both statewide working groups and local, member-led chapters we call “nodes”. We have nodes from the Berkshires to Cape Cod. At the state level, our members conduct focused work ranging from legislative to direct action that supports our campaign goals. We embrace a variety of tactics, all non-violent, that are most likely to further our goals.
