350 Mass was established in 2012 and since that time has been working to build an active grassroots climate movement here in Massachusetts. We are aligned with the goals of 350.org and work to unite the missions of climate, jobs, and justice. 

In the first eight years of our existence we have built 17 single and multi-town nodes across Massachusetts. Our campaigns have included carbon pricing, divestment, 100% renewable energy and the Green New Deal and have helped bring forward climate legislation to the State House every single session. In between, we have empowered local communities to move forward on practical solutions.

Growing the Climate Movement
Through marches, protests, stand-ins, sit-ins, vigils and rallies we have built statewide support. We have marched against coal and gas power plants, pipelines, compressors, other fossil fuel infrastructure. We have marched in support of solar, wind, and “accessible, affordable, reliable and electric” transportation.

Our nodes have run film screenings, guest lectures, webinars, info sessions, activist and anti-racist trainings, and legislator panels. We have tabled at farmers markets and conferences, organized candidate forums, testified and organized environmental justice roundtables. 

Direct action events have highlighted the need to “walk the talk” when it comes to climate change. Members have been arrested protesting pipelines, coal trains and compressor stations. We have supported frontline and indigenous communities from PA to Canada, exposed the hypocrisy of utility companies, and called out the big banks for investing billions to finance climate chaos.

State and Local Action
By increasing our visibility, we have been able to alert people to the urgency of the climate crisis. This has pathed the way for concrete action that is moving us forward to accomplish our carbon neutral, climate justice goals. Through our coalition work we have:

  • Passed the Fair Share Amendment
  • Passed the Act Driving Clean Energy and Offshore Wind, 2022
  • Passed the Next Gen Roadmap bill of January, 2021.
  • Passed non-binding ballot Initiatives with overwhelming support in 19 towns on transparency in government and in 16 towns on 100% renewable energy by 2040.
  • Passed 100% Renewable, Climate Emergency and Green New Deal resolutions as well as detailed, metrics-driven climate action plans in multiple towns.
  • Passed solar roof ordinances and home rule petitions for fossil free, all electric new construction in multiple towns.
  • Passed Community Choice Green Aggregation, selected aggressive default with a high percent of New England Class 1 Renewable energy (e.g. Brookline 37%, Lowell 59%, Newton 80%).
  • Passed No Pipeline Resolutions in 8 towns along the pipeline routes, which helped win the “pipeline tax” battle ending the Access Northeast Project in its tracks.
  • Partnered with MassCEC on Heatsmart and Solarize Mass Plus programs to retrofit homes for renewable electricity.
