*For the CARB reports, every recorded transfer in the district that year, all pollutants; for South Coast 2024, transfers with a stated price. Recent years shown; every recorded year.

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 |
|---|---|---|---|
| NOx | 2.19 t | $356,333– | $780,000– |
| ROG / VOC | 28.84 t | $21,875– | $631,000– |

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.
