350 Mass is a grassroots organization. That means we draw our power from the individuals who engage with and advance our priorities.

350 Mass members are individuals who pledge to take action on the climate crisis by participating in 350 Mass activities, campaigns, node meetings, working groups, and/or the planning thereof. We also collaborate with many other like-minded organizations and coalitions to create educational and public events, press legislative priorities, and create broad bold actions to bring attention to, engage, and solve the many issues that our climate crisis has created in a just and humane way. Your membership dues of $35 (times 10 is our name) are requested annually, but can be subsidized if it is a hardship.
