About Us

350Brooklyn works locally to address the climate crisis through education, legislation and direct action. We are one of more than 200 international affiliates of 350.org

Our History

350Brooklyn was founded in the winter of 2015 by a small group of people who had worked on the 2014 People’s Climate March. Since then we have grown into a vital organization with a steering committee, workgroups, several campaigns, and a mailing list of more than 2300.

We have played a significant leadership role in the campaign to Stop the Williams pipeline, we have been a consistent ally in the passage of the Climate Leadership and Community Protection Act and worked on the city, state and federal level for the passage of the Green New Deal. 

We have developed relationships with numerous legislators, organized town halls, panels, film screenings and rallies, gathered petitions, published op-eds, marched in parades, and performed street theater.

We have formed strong partnerships with an array of organizations at the forefront of the climate movement in NYC. Although we receive no funding from 350.org, we benefit from its resources and leadership on specific issues and campaigns.

Structure and Governance.

Although we are not a 501(c)3 not-for-profit organization, we are under the fiscal sponsorship of the non-profit group SocialGood.  Since our inception we have been an all-volunteer group with a flat, democratic structure.

350BK has a 12-member Steering Committee that meets monthly. Members of the Steering Committee are either leaders of a current campaigns or working groups. The Steering Committee makes all decisions democratically by building consensus.

Once or twice a year the committee gathers to discuss overall strategy and direction.  Every January we dedicate our monthly meeting to report on the progress of the previous year and evaluate our direction for the year ahead.


Our Workgroups

Some workgroups handle our ongoing needs such as art, administration and fundraising and others are based around issues such as the campaign for a Green New Deal or the Cut the Chase campaign. We organize campaigns based on what we perceive as the best opportunities to end the use of fossil fuels and a just transition to a sustainable future.
