About Us

The Regional Climate Protection Authority, RCPA, was formed in 2009 to coordinate countywide climate protection efforts among Sonoma County’s nine cities and multiple agencies. The RCPA fosters collaboration, helps to set goals, pools resources, formalizes partnerships, and works across silos. The RCPA aims to create local solutions to complement State, Federal, and private sector actions – all showing that a better future with lower emissions is possible.
