Who holds sellable ERCs
ERCs are banked, district-certified reductions created when a facility permanently reduces or eliminates a source of pollution, a shut-down boiler, a discontinued rice-straw burn, a closed plant. Agricultural operations, family trusts, manufacturers, and utilities across California hold certificates, many of them for decades, with no easy way to find a buyer.
Reach buyers looking for your credits
District registries record who holds credits. Some include sale flags or contact information, but a listed balance is not a current offer. The Exchange helps buyers find holders, request current quotes and compare available supply.
Listing on the Exchange is free
Holders and brokers post banked certificates at no charge. Each listing is verified against the district registry before it goes live, shows volumes by pollutant, and lets the Exchange desk coordinate buyer inquiries with you or your broker. You set your own price or leave it open to offers. When a sale closes, the purchase is documented in a purchase agreement and the issuing district records the transfer.
Browsing, listing and initial inquiries are free. Brokerage services are available through Brennan, Jewett, Hackett under a separate written agreement. Existing broker relationships are respected. Seller, district and other third-party charges may apply to a transaction.
What we need from you
The district, the certificate number, the pollutants and tonnage banked, and how you would like to be contacted. If you are not sure what you hold, we can pull the district's register for you.
