Why PM10 credits matter

PM10 offsets are required in particulate nonattainment areas, and demand is set to grow: a court has ordered PM2.5 nonattainment designations under the tightened 9.0 µg/m³ standard by February 6, 2027, which will pull new buyers into particulate offset markets statewide.

Buy or sell PM10 ERCs

ERCs are district-bound: a PM10 credit is usable in the district (or, with approval, the air basin) where it was generated. Tell us the district and tonnage your permit requires and we search the registries, contact holders, and can represent you as buyer's broker — no fee to inquire. Holders list free and set their own price.
