Microsoft Signs Largest-Ever Biochar Carbon Removal Agreement

This article describes the details of the deal made between Microsoft and Exomad Green to utilize biochar as a carbon removal solution, supporting the company’s goal of sequestering one million tons of CO2 annually by 2027. Biochar, or biological charcoal, is produced by heating biomass such as forest residue, wood or crop waste in the absence of oxygen, to create a stable form of carbon, which when buried in soil enables centuries-long carbon sequestration.

This is an excellent independent review of the report by Oxford Smith School of Enterprise and the Environment (SSEE) on the cost differences between the two Carbon Capture Storage (CCS) approaches, CCS Heavy, and CCS-Light.  The "heavy" approach uses mechanical extraction of CO2 using complex machinery. The review concludes that CCS-Light is significantly less expensive, and CCS–Heavy may be used on a selective situational basis.
