To support these reporting efforts, CARB staff have developed a methodology for collecting and quantifying information with air districts on statewide strategy progress and air district strategy progress in each of the selected AB 617 CERP communities. The minimum annual reporting requirements are outlined in the Blueprint for CARB statewide strategies and air district strategies. CARB staff uses the information gathered from the annual reporting process to update our Governing Board on AB 617 progress each year and to provide public transparency. CARB has developed a web-based CommunityHub to provide access to annual reporting data and related CERP information, including high-level summaries and links to existing CARB tools. Air districts have also posted annual reports and tracking tools, and where appropriate, links are provided below.
