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.
