Why 350?

To give us a chance to avoid catastrophic, runaway climate change, greenhouse gas emissions must not exceed 350 parts per million of carbon dioxide.  When the industrial revolution began in 1750, the concentration was 278 ppm; as of July 2021, it was 418 ppm. 350 Central Mass is working diligently to bring CO2 below the 350 target without delay.
















Our Mission

  • Work locally, nationally, and globally to ensure a livable planet free of all fossil-fuels.

  • Promote climate justice for all people.  

Our Principles

  • Eliminate the use of all fossil fuels and fossil-fuel infrastructure.

  • Promote a just and sustainable future for all, with special attention to economically marginalized communities, people of color, and Indigenous peoples, who have historically been most at risk from exposure to fossil-fuel infrastructure, such as power plants, oil refineries, pipelines, etc. 

Examples of our Current Work

  • Advocate for legislation and policies to create a 100% renewable electric grid, and build public facilities that are climate-friendly and fair to all residents, particularly poor, minority, and Indigenous communities -- known as environmental-justice communities.

  • Fight construction of fossil fuel infrastructure, such as oil and gas pipelines, natural-gas compression plants, fossil-fueled "peaker" power plants, and biomass electric generation.  

  • Promote disinvestment in fossil-fuel infrastructure by banks and other corporations, educational institutions, and individuals.

  • Promote efforts to electrify everything, including transportation and buildings.

How We Work

  • Engage in campaigns and events through sign-ons, sponsorships, and collaboration with other like-minded organizations.

  • Take direct action through public "stand-outs," rallies, and demonstrations.

  • Lobby legislators through phone, email, social media, and in-person meetings.

  • Advance public understanding of the climate emergency through editorials and letters-to-the-editor, social media, public speaking, rallies, and more.

  • Submit comments in national, state, and local legislative hearings.
