*For the CARB reports, every recorded transfer in the district that year, all pollutants; for the district's own transaction records, sales of that pollutant, at the price per ton the district records. Recent years shown; every recorded year. Sources: Mojave Desert AQMD — ERC Sales Data · CARB 2023 §40709.5 statewide report.
No CO transaction is on record for Mojave Desert AQMD in the 2022 or 2023 statewide reports or in the district transaction records the Exchange holds. For a reference point: the only 2023 CO trades recorded statewide were in Yolo-Solano, at a median of $3,400 per ton. Credits only work in the district that banked them, so local scarcity, not the statewide range, sets the price here. All recorded prices.
Arithmetic only — the recorded volume multiplied by the Mojave Desert median price recorded for each pollutant in 2010–2026, 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 | 941 t | $10,000– | $9.4M– |
| ROG / VOC | 12.05 t | $25,000– | $301,000– |
| PM10 | 3.65 t | $9,000– | $32,859– |
| SOx | 0.04 t | $10,000/t | $445 |
| All pollutants with a recorded Mojave Desert price | $9.7M– | ||
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 Mojave Desert 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 Mojave Desert AQMD, or its air basin with district board approval under Health & Safety Code §40709.6. District office: (760) 245-1661.
