350NYC is a local affiliate of 350.org, a global grassroots network of local groups in over 188 countries working to solve the climate crisis. We participate in global climate campaigns and work locally along with a coalition of allied organizations for a cleaner, greener, better New York for everyone.

350NYC holds a regular monthly meeting that is open to the public.  Meetings are typically held monthly on the 4th Wednesday of the month from 7-9pm at the New York Society for Ethical Culture. We  encourage new folks to come to a short intro session  at 6:30pm before the  general meeting. Please check out our Calendar for updates.

350NYC is an all-volunteer organization that is run by a steering committee and four working groups: one for fossil fuel divestment and legislative action, one for local sustainability solutions and climate education, one for props and art-work for our actions, and one for web and media .

We also encourage members to get involved in planning events and rallies through ad-hoc event planning groups which convene as needed. Members are welcome to propose new initiatives.

Our Allies

350NYC is part of a vibrant and active climate movement in New York City and NY State and much of our work is carried out in collaboration with allies in this broader movement, as well as our network of 350.org affiliates.  Some of these working relationships are based on membership of organizations such as the NYC Grassroots Alliance,   The People’s Climate Movement, NY  (PCMNY),  NY Renews and Divest NY while others are based on support and endorsement climate related campaigns and organizations. See a list of some of these organizations here.


350NYC was founded in 2011 by Lyna Hinkel after she was sent by 350 National to a leadership training at the New Organizing Institute in DC along with 13 other activists from around the country. After the training everyone went back to their home cities and started their local 350 groups. Back then it was hard to even find any news coverage about climate change and though we’ve come a long way since then, so has the climate crisis. See the history of events and actions over the last 6 years. Our monthly newsletter archive can be found here. History of the 350NYC Divestment Campaign here.

What’s in a Name? 

Why the name 350?  350 is the number of parts per million of CO2 in the atmosphere we need to return to in order to preserve our future. Though we were below 350 ppm up until the 1980s, we are now over 400 ppm and rising due to excessive burning of coal oil and gas. (More on the science of 350).  350NYC is  working for a just transition to 100% renewable energy.
