Cement consumption, bolstered by residential construction, has seen a sharp increase in emerging
countries over the past twenty years. This impetus leads to an often high level of per capita
consumption and is expected to continue of the next two decades. The cement industry may
support economic development, but its manufacturing process is responsible for a considerable
amount of CO2 emissions. The efforts that have been made since the 1990s have, however, reduced
CO2 emissions per ton of manufactured cement.
