This has been one of the inherent problems with any kind of carbon removal — there’s no real way to profit from it, so it was unlikely to happen at scale bigger than a PR operation unless government either pays for it or requires firms to pay for it.
The cost of carbon capture should be passed on to the producers of carbon. That’s the fastest way to get them to stop.
The trouble is, we’re too afraid to regulate businesses out of business.
This is entirely the point of a cap and trade system. Let the market duke it out over the best path to zero, ratcheting down the amount of credits on the market, so everyone can decide whether to focus on reducing or removing.
