Decarbonizing the Cement and Concrete Sector
Published on
75% of the global urban infrastructure that will exist in 2050 is yet to be built, and it will almost all be built in developing countries. This infrastructure will require cement, which does not have an intrinsically high carbon footprint, but because of the quantity of its demand and use, is responsible for 8% of global emissions. Emissions reductions can be made at all levels of cement production through a prioritization of material efficiency in creation, use, and design. For example, using clinker alternatives in cement production, using cement efficiently through industrialization, and optimizing building design, can reduce emissions by almost 80%.
