Durable CDR market grew 151% CAGR excluding Microsoft and Frontier purchases

The durable carbon dioxide removal (CDR) market saw a 151% compound annual growth rate (CAGR) in purchases from 2021 to 2025, excluding volumes from Microsoft and Frontier, according to CDR.fyi. While Microsoft accounted for 78.5% of all disclosed durable CDR tonnes purchased by April 2026, its recent pause serves as a market stress test. Biomass Carbon Removal and Storage (BiCRS) methods, particularly BECCS and biochar, led near-term execution, comprising 96% of purchase volume and 91% of delivered volume in 2025. The market is transitioning to reward execution, with pricing becoming method-specific and financing favouring operationally disciplined suppliers. This indicates a more selective market, moving from ambition to tangible delivery and retirement of CDR credits.
