Carbon removal contracts must differentiate between biological and industrial project profiles

Reaching gigaton-scale carbon removal will require significant public government procurement
“There will definitely be a moment for government demand. I think when you look at the IPCC numbers for five plus gigatons, five to 10 gigatons of carbon removal, you need public procurement to play an essential role of that.”
