In Canada when the price of natural gas goes up the cement manufacturers convert back to using coal in their furnaces. This is another reason why a price on carbon is so important.

Read up on Calera again. They dropped all claims of making cement and switched to “concrete filler” (ie gravel/limestone). The original claims were physically impossible and there is still some question of whether or not their process is net carbon negative.
