Reserve Sale Schedule 

The California Cap-and-Trade Program Reserve Sale Summary of Potential Dates includes the potential Reserve sale dates for 2020.

Greenhouse Gas Allowance Price Containment Reserve Sales

As part of the Cap-and-Trade Program, California will offer sales of allowances from the Allowance Price Containment Reserve (APCR) in any quarter that the Current Auction held in the preceding quarter resulted in a settlement price greater than or equal to 60% of the lowest Reserve tier price. Prior to the November 1 compliance obligation instrument surrender deadline, a sale of allowances from the APCR (Reserve sale) will be held without regard to the settlement price in the Current Auction held in the preceding quarter.

Reserve sales are scheduled pursuant to the schedule in Appendix C of the Cap-and-Trade Regulation. California's Reserve sales will offer GHG allowances from the APCR for sale in three fixed-price, equal-sized tiers.

Reserve sale notices are posted on this webpage at 12:00 PM PT, approximately thirty (30) days prior to each offered Reserve sale. If the date for posting a Reserve sale notice falls on a weekend or holiday, the notice will be posted no later than the next business day. The Reserve Sale Notice provides information about eligibility, Reserve sale format, and APCR allowances offered for sale.

If there are no qualified applicants or qualified bidders for any offered Reserve sale, then that Reserve sale will not be held. If a Reserve sale will not be held, CARB will post a notification to this webpage no later than two (2) days prior to the offered Reserve sale.
