Essd Global Co2 Emissions From Cement Production,
Abstract. global production of cement has grown very rapidly in recent years, and, after fossil fuels and landuse change, it is the thirdlargest source of anthropogenic emissions of carbon dioxide. the availability of the required data for estimating emissions from global cement production is poor, and it has been recognised that some global estimates are significantly inflated.
