Once again, I'll answer in a more technical way. Indeed, when we talk about metallurgical carbon, which is used to reduce iron to cut emissions, we can use anthracite, a traditional product, or products derived through a thermochemical process to produce metallurgical-grade biochar. The cost is higher.
So we need a carbon policy, an incentive or regulations, which can take various forms. Again, I'm not a lawyer. It could be a carbon tax, a specific requirement regarding the use of biochar in a metallurgical process or in something else. It is possible and feasible, but we need regulations to support it. If we rely purely on the economy, it won't work.
However, in my opinion, every policy must be part of a long-term vision. We have to think about the day when we won't need the policy anymore. Otherwise, we'll just create widespread inflation. So how do we balance the two? It's your job to answer that question. All I can do is provide you with data, unfortunately.
