Important Notes

• This online tool enables users to locate, view, and analyze emissions of greenhouse gases (GHG) from large facilities in California.
• GHG emissions data were collected through the ARB’s Mandatory Greenhouse Gas Reporting Program.
• The data used in this tool do not reflect the total GHG emissions in California. For complete GHG emissions information, please visit ARB's Greenhouse Gas Emission Inventory.
• Only emissions directly emitted from California facilities are represented. Emissions from imported electricity and fuel suppliers are not included.
• Not all of the entities covered by the Cap-and-Trade Regulation are presented in this tool. Please read the Legal Disclaimer for more information.
• The primary sectors of facilities were reconciled for consistency between the old and the current reporting regulations.
• ARB will update the tool periodically when new data become available.
