Editorial interest 78/100 Selection signal · not a rating of the site

A marketplace for California Emission Reduction Credits, with sale listings and a searchable register of banked certificates.

Landing page captured for the 2026-10-23 issue.

For: California businesses seeking or holding ERCs
Worth noticing: The register lists 4,918 certificates from 17 district registers, while distinguishing public records from current sale inventory.

Field notes

Sale listings display certificate identifiers, air districts, pollutant quantities, and availability status; prices are generally listed as available on request. The register is a separate research layer: its district counts describe banked certificates, not verified offers to sell. The homepage identifies source dates and coverage notes as relevant when checking records, and says Bay Area records include owner-reported sale-availability flags.
