The Massachusetts Sierra Club is the state chapter of the largest, oldest, and most influential environmental grassroots organization in the country. With a small staff supporting volunteer leaders and over 85,000 members and supporters across the state, we are volunteer-driven with a mission: To explore, enjoy, and protect the planet; to practice and promote the responsible use of the earth's ecosystems and resources; to educate and enlist humanity to protect and restore the quality of the natural and human environment; and to use all lawful means to carry out those objectives.

What do we do here in Massachusetts?

• We push for a just transition to an equitable clean energy economy. 
• We advocate for efficient, clean transportation for all.
• We work to reduce toxic pollution and to move toward zero waste.
• We fight back against threats to our communities' health and environment.
• We believe in helping people explore and enjoy the natural world.

Sierra Club understands that the crises of income inequality and climate change are inextricably linked. This is why we are an avid supporter of the THRIVE Act and RENEW New England, based on three essential pillars:

1) Tackling the climate crisis and toxic pollution

2) Creating good, high-paying jobs

3) Fighting racial, economic, and gender inequity

Volunteer with us to support a just transition in Massachusetts.

Climate justice and racial justice are also inextricably linked, and the Massachusetts Chapter is dedicated to being an actively anti-racist organization. We rise in solidarity with the Movement for Black Lives list of demands, and why we will continue to learn from and fight alongside racial justice organizations. Since June 2020, the Chapter has: 

• Released an Equity and Justice Roadmap 

• Published a list of Anti-Racism Resources 

Contact us to learn how you can engage with the Chapter’s anti-racism work.

2020 was the end of the hottest decade on record, and according to the UN’s recently released IPCC report, we must act now to cut carbon pollution in half in the next ten years and eliminate it altogether by 2050 to avoid the worst impacts of climate change.

We’re in a climate crisis. We must make changes in the way we live, from where we get our energy to how we get from place to place. Are you ready to make a positive impact in your environment?
