This process is one part of a methodology for Biological Carbon Capture and Storage (BCCS). Picture it as an equation: it begins with accounting for the carbon we bring into the short-term carbon cycle by burning fossil fuels. By measuring the amount of carbon sequestered in biochar, we can account for removing an equivalent amount of carbon from the short term carbon cycle. By accurately measuring and certifying the rate at which carbon is added and removed, in a real-life process, we can show the cost of balancing the atmospheric concentration of carbon through gasification & biochar.
This creates a basis with which a dollar value could be applied to both sides of the equation, developing a market-based mechanism for nations, companies and individuals to “clean up” their carbon emissions. In our vision the farmers supplying the biomass used for carbon sequestration will sequester the biochar in the same soil crops grow from. They will “export” a certificate indicating to the purchaser the number of atoms of carbon they have sequestered. To guarantee quality and transparency of the system, there will be rigorous third-party testing and monitoring. Given the necessary and sufficient conditions, sequestered carbon or "Carbon Negative Negative" could have its own commodity market.
This is a massive undertaking with a global vision; clean air is an international public good. The governance challenges that must be overcome to implement this effort with a reasonable chance of success are unprecedented in the history of human affairs. By showing how the method could be implemented, we hope to encourage the possibility of this market-based solution to the problem of private overuse of this public good.
