The Contra Costa County Climate Leaders (4CL) program is a network assisting the county and its 19 cities to inform, support and encourage the measurement and reduction of greenhouse gas emissions. Through education and sharing of best practices we will ensure sustainable, healthy and livable cities.

GHG Inventories


Fifteen of the 19 Contra Costa County cities and the County, participated in three of four workshops offered under a grant from the San Francisco Foundation to ICLEI member cities. During the first three workshops, cities were introduced to ICLEI’s CACP software for completing a Greenhouse Gas (GHG) inventory, completed a community-wide GHG inventory for their city, and discussed opportunities for setting city targets similar (or beyond) the Kyoto Protocol.
