Support 350 Mass Action!

Become a member and make climate change a priority in the upcoming elections!

Join us as a member with an annual dues-donation of $20 or more. Members nominate candidates for potential endorsement, help evaluate candidates nominated by others, and vote in the endorsement process! Members can also get directly engaged with candidates’ campaigns -- providing crucial “boots on the ground” and backup support for both local and state-level races, promoting climate issues in the media and to voters, and helping ensure that our elected leaders serve Massachusetts residents, not the interests of the fossil fuel industry.

Donate generously -- your membership money has a direct impact on the scope of our work. Because donations to a politically active 501(c)(4) like 350 Mass Action are not tax deductible so cannot come from private foundations, we rely almost exclusively on grassroots donors like you to fund our work. Whether you can afford $10 or $10,000, please pitch in. A strong, contributing membership base will enable us to match our work to the urgency of climate change, in the voting booth and beyond.

Thank you for your support!
