*For the CARB reports, every recorded transfer in the district that year, all pollutants. Recent years shown; every recorded year. Sources: CARB 2023 §40709.5 statewide report · CARB 2022 §40709.5 statewide report.
No CO transaction is on record for Bay Area 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 Bay Area median price recorded for each pollutant in 2022–2023, 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 | 480.3 t | $22,000– | $10.6M– |
| ROG / VOC | 284.6 t | $9,125/t | $2.6M |
| PM10 | 1.1 t | $20,000/t | $22,000 |
| SOx | 460.1 t | $10,026/t | $4.6M |

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 Bay Area 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 Bay Area AQMD, or its air basin with district board approval under Health & Safety Code §40709.6. District office: (415) 749-5000. District ERC program page.
