Purchase prices are the figures the district recorded when a certificate changed title, in $ per lb/day as South Coast quotes them; the per-ton figure is the straight conversion (1 lb/day = 0.1825 tons per year). Certificates marked "Internal Transfer", "Reissue" or with no price moved without a sale.

Arithmetic only — the recorded volume multiplied by the South Coast median price recorded for each pollutant in 2022–2024, shown as a range because the medians moved between years. Not an appraisal, an offer, or a prediction; actual bids depend on the buyer's permit deadline, the lot size, how many trades the median rests on, and what else is available in the district.
| Pollutant | Volume | × recorded median | Reference |
|---|---|---|---|
| ROG / VOC | 9.31 t | $21,875– | $204,000– |
| PM10 | 4.38 t | $319– | $1,396– |
| SOx | 8.21 t | $1,191– | $9,777– |
| All pollutants with a recorded South Coast price | $215,000– | ||
The buyer and holder agree a price privately. The transfer package — the holder's authorization, the purchase agreement, and the district's transfer forms — goes to South Coast AQMD, which verifies the banked reductions, records the transfer, and re-issues the certificate (or the remaining balance) in the buyer's name. Credits are generally usable only inside South Coast AQMD, or its air basin with district board approval under Health & Safety Code §40709.6. District office: (909) 396-2000.
