Cap-and-Trade Program Data
Contact
The California Air Resources Board (CARB) provides a wide range of information on every aspect of the Cap-and-Trade Program. This information ranges from the bedrock reporting and third party verification of greenhouse gas (GHG) emissions through allocation, offsets, compliance, auction announcements and results, use of auction proceeds, market data and enforcement. Because the Cap-and-Trade Program deals with multiple private and public companies, certain types of information – typically those related to Confidential Business Information – may be protected from disclosure pursuant to the California Public Records Act (PRA) and other applicable privacy laws.
The overview of publicly available information describes these data publications in more detail. The Cap-and-Trade Program Data Dashboard provides charts for many of the reports on this page. A video presentation which provides examples of data uses and an overview of publicly available data is available at the bottom of this page.
