Don’t forget steel and concrete! Every pound of concrete releases 1 pound of CO2

Half of that is from the chemical transformation of limestone to quicklime, and half of it is from the fuel energy currently used to drive the transformation:

So if carbon-neutral fuels or clean electricity were substituted in the calcination process, the CO2 burden would be reduced by half without any additional downstream changes.

I think you mean cement. Cement is only 10-15% of concrete. The rest is water and rock/sand.
