Sustainable Contra Costa will share new actions through the Cleaner Contra Costa Challenge, a free platform where you can work with others to reduce your household greenhouse gas emissions. By working together to reduce food and household waste, we can also fight climate change! We will help you start Teams through the Cleaner Contra Costa Challenge and work with others to create a cleaner and healthier Contra Costa for the future. (This project is funded through a grant from the Bay Area Air Quality Management District.)
