The manufacture of cement, which serves as the binding agent in concrete, accounts for roughly 8 percent of global carbon dioxide emissions, a significant share of the total. This is because making cement involves using immense amounts of mechanical and heat energy to quarry rock for limestone and extract the lime by way of a high-temperature treatment process.
