It adds up to contribute about 8% of the world’s total carbon dioxide (CO2) emissions. The process emits CO2 in two different ways. First, it requires heating a kiln to high temperatures, which uses energy. Second, in the process of mixing cement into concrete, another transformation takes place — calcination. This is when limestone gets heated, turning it into quicklime. 2. Increase in Production The world’s population is growing. This means more buildings. Cement production continues to rise each ye
