Environmental impact of concrete - Wikipedia

Carbon dioxide emissions and climate change. The cement industry is one of the two largest producers of carbon dioxide (CO 2), creating up to 8% of worldwide man-made emissions of this gas, of which 50% is from the chemical process and 40% from burning fuel. The CO 2 produced for the manufacture of structural concrete (using ~14% cement) is estimated at 410 kg/m 3 (~180 kg/tonne @ density of 2 ...
