Developed first in a how-to book, the program is co-led by a group of neighbors living on a city block. CommonPlaces Interactive developed a custom website application that brought all the robust functionality of the Cool Block program online and mobile which allows participants to select from 112 action recipes that lower carbon emissions, increase their disaster resiliency and enhance the livability of their block

Cool Blocks began in California and will be adding more states to the project, and ultimately adding communities around the world. The end goal is to mobilize at least 25 percent of households to reduce their CO2 footprint by at least 25 percent.
