Organizing the climate crisis’ most disproportionately impacted communities is the missing ingredient to build power required to address the climate crisis. In order to meet the climate crisis and transform our society, we must scale up grassroots organizing. Organizations affiliated with the Center for Popular Democracy that are now leading some of the strongest climate justice organizing in the country include the Green New Deal Network, New York Communities for Change, Make the Road PA, One PA, CASA, the PA statewide climate table, and Florida Rising, and others. This report profiles the work of those groups and others organizing working-class communities of color into the climate movement. Organizing must be: 1) community-led and focus on issues that have tangible impacts for Black, Indigenous, Latiné, and low-income people, 2) rooted in a framework that challenges racial capitalism, and 3) intersect with other issues impacting frontline communities.
