How practical is ‘carbon to stone’?
Re “Scientists find a way to turn carbon dioxide into stone,” June 10
In my opinion, “carbon to stone” is utterly impractical as a method. You still must separate carbon dioxide from other gases and pump billions of tons underground, requiring an infrastructure as vast as current oil pipelines. Such sequestering would raise the cost of coal, which is already more expensive than wind and solar.
Unfortunately, the public could easily be seduced into the false hope of “carbon to stone.” Science is going to solve this after all, so there’s nothing to concern ourselves about, the thinking might be.
The most powerful and least painful policy to reduce emissions is a revenue-neutral carbon price, with all money collected returned to the public. Then we can come to grips with the greatest threat our species has ever faced.
