CDR Verification
Forensic verification of biochar production, sequestration rates, and carbon removal permanence for §45Q credits and voluntary carbon markets.
The Market
Biochar-based carbon dioxide removal (CDR) is one of the few sequestration methods recognized for 1,000+ year permanence. Under §45Q of the Internal Revenue Code, qualifying carbon capture and sequestration projects can claim up to $180/ton for direct air capture and $60/ton for point-source capture.
The voluntary carbon market increasingly demands MRV (Measurement, Reporting, and Verification) infrastructure that meets registry standards like Puro.earth, Verra, and Gold Standard. Unverified claims face growing buyer skepticism and regulatory scrutiny.
