Auction Notices and Reports

In November 2014, the California Air Resources Board (CARB) and the Québec Ministère de l'Environnement, de la Lutte contre les changements climatiques, de la Faune et des Parcs (MELCCFP) began holding joint greenhouse gas (GHG) allowance auctions to allow market participants to acquire GHG allowances. Prior to the first joint auction, as part of the Cap-and-Trade Program, CARB held eight (8) jurisdiction specific quarterly GHG allowance auctions beginning in November 2012.
Summaries of Cap-and-Trade Program auction settlement prices and results and auction proceeds are available below.
The table below provides Auction Notices, Summary Results Reports, and California Post Joint Auction Public Proceeds Reports for each auction. Auction Notices are supplemented with additional materials providing detailed requirements and instructions for participating in a joint auction as well as examples of how to determine the amount of a bid guarantee, how holding and purchase limits are applied, how U.S. and Canadian currencies are handled, and examples of how joint auctions are settled. The most recent supplemental material is provided with the most recent Auction Notice posted at CARB Auction Information. Supplemental materials for prior auctions are available from CARB staff.
