Concrete has a large environmental footprint, mostly due to it being a cement product. It takes a huge amount of energy to heat limestone, cement’s key ingredient, and subsequent chemical processing required. The process of creating cement emits upwards of 80% of the cement’s weight in carbon dioxide and accounts for about 5% of human-generated CO2 emissions annually.
