No CO transactions were reported to CARB for Yolo-Solano AQMD in 2022. See the statewide price tables and CO prices in other districts for a reference range; local scarcity sets the price.
CO offset demand is episodic — most districts attain the CO standard — but large banked CO volumes exist (single certificates exceed 100 tons) and typically price accessibly, trading alongside other pollutants.
ERCs are district-bound: a CO credit banked in Yolo-Solano AQMD is usable in Yolo-Solano AQMD (or its air basin with district board approval).
