The cement industry is without doubt one of the three Key producers of carbon dioxide, a major greenhouse gas – the opposite two becoming Electrical power manufacturing and transportation industries. On ordinary, every single tonne of cement produced releases one particular tonne of CO2 to the environment. Pioneer cement companies have claimed to achieve lower carbon intensities, with 590 kg of CO2eq for each tonne of cement generated.[a hundred thirty five] The emissions are because of combustion and calcination processes,[136] which approximately account here for forty% and 60% on the greenhouse gases, respectively.
