350 Mass Action is a statewide volunteer network working to address the escalating climate crisis by eliminating greenhouse gas emissions and moving our world to a 100% clean, sustainable, and just energy future. Since our founding in 2016, our primary focus has been electing progressive climate champions and eliminating the influence of fossil fuel special interests over our political process.

We help create the political will for government to take needed action by holding elected officials accountable, organizing public education and mobilizations, pushing for candidate pledges campaigns, supporting ballot questions, participating in corporate- and government-focused direct action campaigns, endorsing and supporting candidates for political office, and other activities. and for political office.

  • Cambridge-Somerville
  • South Shore
  • Allston-Brighton
