> Aren't most concrete carbon emissions due to energy consumption nope. about 1/3 is from energy consumption, 2/3 are due to the chemical processes involved see Figure 1 here: https://www.umweltbundesamt.de/sites/default/files/medien/1410/publikationen/2022-01-04_climate-change_02-2022_decomposition_of_co2_emissions_in_the_european_cement_sector_0.pdf https://www.umweltbundesamt.de/sites/default/files/medien/14... the consumed energy is electricity (Wind or Photovoltaics), which is cheap, see sibling comments and plenty (also see sibling comments)
