The cement market is one of the a few Major producers of carbon dioxide, An important greenhouse fuel – the opposite two becoming Strength production and transportation industries. On ordinary, each tonne of cement made releases just one tonne of CO2 to the atmosphere. Pioneer cement producers have claimed to succeed in reduced carbon intensities, with 590 kg of CO2eq per tonne of cement manufactured.[135] The emissions are due to combustion and calcination processes,[136] which roughly account for forty% and sixty% in the greenhouse gases, respectively.
