Better Future Project is a Cambridge-based climate organizing nonprofit founded in January 2011. In spring 2012, Better Future Project staff began a series of meetings and conversations with fellow activists about the need for a grassroots climate network in Massachusetts. Those conversations grew out of many years of collaboration on 350.org actions and events, and they led to the creation of 350 Massachusetts for a Better Future as a volunteer-led, campaign-focused network.

350 Mass began with one node in Cambridge in June 2012. With support from Better Future Project staff, 350 Mass has grown into a much larger network with nodes in nearly every part of Massachusetts.
