This process is typically referred to in the scientific literature as "enhanced" weathering but we think that "accelerated" weathering is easier for lay people to understand.
Drawdown is mostly focused on things we can change in our current activity to lower emissions and less about methods for Carbon Dioxide Removal (CDR). Their top solution for becoming carbon neutral is "Refrigerant Management"...
I like the concept of the project and know some people working in the org, but in my opinion, they do not give enhanced/accelerated weathering enough credit as a potential solution, even though it can scale all the way up to global CO2 level emission removal. Many of the other solutions they suggest are limited in potential, yet featured prominently... I am working to communicate this to them.
